[0002] This application claims priority to U.S. Patent Application No. 16 / 999,154, filed August 21, 2020, the contents of which are incorporated by reference herein. TECHNICAL FIELD

[0003] The present disclosure relates generally to valve devices, valve actuation devices, and related systems and methods. Certain such embodiments are described herein in the context of medical fluid injection systems as one example type of application. BACKGROUND

[0004] Valves can be used to control fluid flow in a variety of contexts, including medical contexts. For example, certain medical procedures can include introducing a fluid into a patient. Various medical devices, such as fluid injection systems, can be employed to introduce the fluid into the patient. Injection systems can be used for a variety of medical applications, including introducing a fluid into a patient to facilitate a medical diagnostic and / or interventional procedure. In some such procedures, the fluid can aid in collecting information, such as image data, at an area of interest within the patient. The collected information can be used, for example, to determine characteristics related to a diagnostic procedure and / or to guide placement of one or more medical devices during an interventional procedure.

[0005] In connection with particular procedures, such medical devices can selectively start and stop injection of fluid into a patient at least in part by opening or closing a fluid pathway to the patient. To do so, one or more valves can be actuated to selectively open and close one or more fluid pathways to the patient. SUMMARY

[0006] Generally, various embodiments are disclosed herein relating to valve devices, valve actuation devices, and related systems and methods. In particular, embodiments are disclosed herein of valve actuation devices configured to be coupled to valve devices. When coupled, the valve actuation devices can actuate the valve devices to open and close fluid passages at the valve devices.

[0007] In certain applications, the valve device can be attached to a component placed in the system during setup in a manner that can cause variability in the precise position of the valve device from one setup to another. In the case of a fluid injection system, the valve device can be attached to a fluid reservoir. In setting up the fluid injection system, a portion of the fluid reservoir can be placed in engagement with a drive ram of the fluid injection system, thereby in this particular case making the precise position of the valve device dependent on the placement of the fluid reservoir. This variability in the precise position of the valve device from one setup to another can be caused at least in part by unavoidable manufacturing tolerances between the valve device, the valve actuation device, and / or the fluid reservoir. This variability can result in substantial misalignment between the valve device and the valve actuation device, making proper coupling of these components difficult. Without the ability to compensate for this variability, substantial misalignment can result in stresses being placed on one or more of the coupled components, which can result in connection and / or component failure.

[0008] Various valve actuation device embodiments can be useful, for example, to facilitate alignment between the valve actuation device and the valve device so that the valve actuation device can be properly coupled to the valve device. Embodiments disclosed herein can provide a valve actuation device that can accommodate variable positions of the valve device and thereby compensate for misalignment with the valve device. In particular, embodiments of the valve actuation device can include a valve actuation coupling that is movable in a manner that aligns the valve actuation coupling with a valve member coupling of the valve device to facilitate proper coupling between the valve actuation coupling and the valve member coupling. It is noted that the ability of the valve actuation device to compensate for misalignment with the valve device can reduce stresses placed on one or both of the valve device and the valve actuation device, thereby reducing the risk of connection and / or component failure and increasing the useful life of these components.

[0009] One embodiment includes a fluid injection system. The fluid injection system includes a valve device and a valve actuation device. The valve device includes a valve member and a valve member coupling. The valve member defines a fluid passage. The valve member has an open position that allows fluid to pass through the valve device via the fluid passage and a closed position that prevents fluid from passing through the valve device via the fluid passage. The valve member coupling is configured to transition the valve member between the open position and the closed position when actuated. The valve actuation device includes a valve actuation coupling and a drive mechanism. The valve actuation coupling is coupled to the valve member coupling and the drive mechanism. The valve actuation coupling is movable independently of the drive mechanism to couple the valve actuation coupling to the valve member coupling. Also, the valve actuation coupling is movable with the drive mechanism to actuate the valve member coupling to transition the valve member between the open position and the closed position.

[0010] In another embodiment of a fluid injection system, the valve actuation link can be moved independently of the drive mechanism in a direction that allows the valve actuation link to align with the valve member link. As one such example, the drive mechanism can be configured to rotate about a drive axis, and the valve actuation link can be moved independently of the drive mechanism in a direction away from the drive axis. In this example, the valve member link can be located at a position offset from the drive axis, and the valve actuation link can be moved independently of the drive mechanism to the position offset from the drive axis.

[0011] Another embodiment includes a valve actuation apparatus. The valve actuation apparatus includes a drive mechanism and a valve actuation link. The drive mechanism is configured to rotate about a drive axis. The valve actuation link is coupled to the drive mechanism. The valve actuation link is movable independently of the drive mechanism in a direction away from the drive axis to couple the valve actuation link to a valve member link. Also, the valve actuation link is movable with the drive mechanism to actuate the valve member link to transition the valve member between an open position and a closed position.

[0012] In another embodiment of a valve actuation apparatus, the valve actuation apparatus includes a restriction plate defining a hole therethrough. The hole has a first dimension and a second dimension perpendicular to the first dimension. The valve actuation link extends through the hole of the restriction plate. The valve actuation link is movable independently of the drive mechanism in a direction away from the drive axis along the first dimension. Also, the second dimension is sized to limit movement of the valve actuation link independently of the drive mechanism in a direction away from the drive axis along the second dimension to be less than movement along the first dimension.

[0022] The following detailed description is exemplary in nature and is not intended to limit the scope, applicability, or configuration of the application in any way. Rather, the following description provides some practical illustrations for implementing embodiments of the application. Examples of constructions, materials, and / or dimensions are provided for selected elements. Those skilled in the art will recognize that numerous suitable alternatives can be utilized.

[0023] Figure 1 A perspective view of an exemplary embodiment of a fluid injection system 100 is shown. In operation, the fluid injection system 100 can inject an amount of fluid into a patient, e.g., into a blood vessel of the patient, via a catheter. The fluid injected by the fluid injection system 100 can be, for example, a contrast fluid, a non-contrast fluid (e.g., saline), or a combination thereof. By injecting an amount of fluid into the patient, the fluid injection system 100 can facilitate various medical diagnostic and / or interventional procedures, including the collection of image data representative of an anatomical region of interest. As examples, such procedures can include optical coherence tomography (OCT) imaging, intravascular ultrasound (IVUS) imaging, computed tomography (CT) imaging, magnetic resonance imaging (MRI), angiographic procedures, and interventional device procedures / placements.

[0024] ​The illustrated fluid injection system 100 includes a drive assembly housing 102 and a sleeve 104. The sleeve 104 can be attached to the drive assembly housing 102. For example, the drive assembly housing 102 can include an opening, and the sleeve 104 can be secured to the drive assembly housing 102 at or near the opening. The sleeve 104 can extend from the drive assembly housing 102 and can be configured to receive and secure a fluid reservoir 106 thereat. Although Figure 1 The example illustrated in FIG. 1 shows one fluid reservoir 106, but other fluid injection system embodiments can include two (or more) fluid reservoirs 106 and a corresponding number of sleeves 104. The fluid reservoir 106 can define an internal reservoir volume that includes a plunger 108. At least a portion of a drive assembly can be housed within the drive assembly housing 102.

[0025] The drive assembly can be configured to pressurize fluid within the internal reservoir volume. For example, the drive assembly can be coupled to the plunger 108 via a drive ram, such as at an opening in the drive assembly housing 102, and the drive ram can drive the plunger 108 within the internal reservoir volume of the fluid reservoir 106. As the plunger 108 is progressively driven within the fluid reservoir 106 (e.g., in a direction toward an outlet of the fluid reservoir 106), fluid within the internal reservoir volume can be pressurized and output from the fluid reservoir 106 along a fluid line 109 leading to a catheter 126 that is inserted into a blood vessel of a patient to inject fluid into the vasculature. In certain applications of the fluid injection system 100, the output fluid, such as a contrast media, can be pressurized to any value (e.g., 1200 psi) in a range of 1000-1500 psi. In embodiments that include two (or more) fluid reservoirs 106, a corresponding number of drive assemblies can be housed within the drive assembly housing 102 in order to pressurize fluid within each fluid reservoir.

[0026] The illustrated embodiment of fluid injection system 100 includes several features that can be used to pressurize and deliver fluid during operation. For example, fluid injection system 100 can include a control panel 110. Control panel 110 can provide a user interface for various operational aspects. For example, an operator can utilize control panel 110 to set various parameters and / or protocols for a given fluid injection procedure. Control panel 110 can also be used to initialize fluid injection system 100 (e.g., to prepare for a fluid injection for a patient), or to initiate certain features or sequences of operations. In some cases, as illustrated here, a hand control 113 can be coupled to control panel 110 and used by an operator to remotely input injection-related commands to fluid injection system 100. Control panel 110 can also provide status information, including information related to past or currently ongoing injection procedures, as well as any appropriate alerts. Control panel 110 can include a processing engine having one or more processors for controlling operation of fluid injection system 100. Such processors can also communicate with and / or control other components connected to fluid injection system 100, such as a drive assembly, a peristaltic pump 112 (when present), and / or any sensors and detectors (e.g., air detection sensor 128 and / or a hemodynamic pressure transducer).

[0027] The fluid injection system 100 can also include one or more components for supplying fluids for use in an injection procedure. In applications where two fluids are to be injected into a patient, a fluid supply container 114 and a fluid supply container 118 can be fluidically coupled to the fluid injector 100. As one example, the fluid supply container 114 can be a contrast fluid supply container, and the fluid supply container 118 can be a flushing fluid (e.g., saline) supply container. As shown here, a holder 116 can be included at the fluid injection system 100 to hold the fluid supply container 114, and a holder 120 can be included at the fluid injection system 100 to hold the fluid supply container 118. In the illustrated embodiment, fluid (e.g., contrast fluid) from the fluid supply container 114 can be supplied to the fluid reservoir 106 for use during an injection procedure. For example, as the plunger 108 is retracted (e.g., moved in a direction toward the drive assembly housing 102 and away from the outlet of the fluid reservoir 106), fluid from the fluid supply container 114 can be drawn into the fluid reservoir 106 to create a negative pressure within the fluid reservoir 106 to refill the internal reservoir volume. In the illustrated embodiment, the fluid injection system 100 includes a peristaltic pump 112 for delivering fluid from the fluid supply container 118 to the patient. Generally, the peristaltic pump 112 can be used to deliver non-contrast flushing fluid, such as saline, at a lower pressure than the pressure at which the drive assembly delivers contrast fluid from the reservoir 106. However, as noted, in other embodiments, the fluid injector 100 can include a second fluid reservoir 106 and use a corresponding drive assembly housed within the drive assembly housing 102 to pressurize and deliver non-contrast fluid from the fluid supply container 118. In some such embodiments, the second fluid reservoir 106 and corresponding drive assembly can be present in place of the peristaltic pump 112.

[0028] A manifold connector 124 can be included to selectively place one of the fluid reservoir 106 and the peristaltic pump 112 (or the second fluid reservoir 106, depending on the embodiment) in communication with the patient. Thus, the manifold connector 124 can selectively place fluid from the fluid supply container 114 and fluid from the fluid supply container 118 in communication with the patient. For example, in response to a change in pressure, the manifold connector 124 can switch from allowing fluid communication to the patient from one of the fluid reservoir 106 and the fluid supply container 118 to allowing fluid communication to the patient from the other one of the peristaltic pump 112 (or the second fluid reservoir 106, depending on the embodiment) and the fluid supply container 118. A patient interface connector can also be included, for example at the fluid line 109, to selectively allow fluid (e.g., from the manifold connector 124) to pass, for example, to a patient interface component (e.g., a catheter, such as an injection catheter). The patient interface connector can include a valve configured to selectively allow fluid to pass through the patient interface connector.

[0029] As described above, one or more sensors may be connected to the fluid injection system 100 to provide information related to the injection. In the illustrated embodiment, an air detection sensor 128 and a hemodynamic pressure transducer are connected to the fluid injection system 100. The air detection sensor 128 can be configured to detect the presence of air (e.g., one or more bubbles) in one or more components. As shown here, the air detection sensor 128 can be configured to detect the presence of air in the fluid line 109 at a position between the outlet of the manifold connector 124 and the patient. For example, the fluid line 109 can have an air detection interface at which the air detection sensor 128 can detect the presence of air in the fluid line 109. When such air is detected, the air detection sensor 128 can output a signal at the fluid injection system 100, and the fluid injection system 100 can take corresponding actions, such as stopping the injection and / or providing a warning to the user. The hemodynamic pressure transducer can be configured to measure, for example, the pressure in the fluid line 109. When manifold connector 124 is opened such that the hemodynamic pressure transducer is in fluid communication with the patient, the hemodynamic pressure transducer may output a signal corresponding to the pressure inside the patient.

[0030] Preparing a fluid injection system for use may require multiple steps. Because some components used for fluid injection are routinely replaced (e.g., after a single use, after a predetermined number of uses), preparing a fluid injection system for use may include frequently replacing new components and properly coupling the new components together. Component couplings should generally be precise in order to reduce stress on the coupled components and prevent component failure and / or fluid leakage. Therefore, replacing and properly coupling components in a fluid injection system can consume considerable time and require detailed attention. However, certain fluid injection system applications may be time sensitive and may make it difficult to focus in real time on the details required to properly prepare a fluid injection system for such applications. This is particularly true where two components may not be precisely aligned in the same manner from one fluid injection system setup to another.

[0031] The present disclosure describes embodiments that can facilitate alignment between coupled components. This can be useful in applications where the precise position of a coupling can vary from one coupling to another (e.g., from one fluid injection system setup to another). As will be further described below, valve actuation device embodiments disclosed herein can be useful, for example, in facilitating alignment between a valve actuation device and a valve device to enable the valve actuation device to properly couple to the valve device. Embodiments disclosed herein can provide a valve actuation device that can accommodate a variable position of a valve device and thereby compensate for misalignment with the valve device. The ability of a valve actuation device to compensate for misalignment with a valve device can reduce stress exerted on one or both of the valve device and the valve actuation device, thereby reducing the risk of connection and / or component failure and increasing the useful life of these components.

[0032] Figure 2 and 3A -3C illustrates an embodiment of a fluid reservoir 206 and an embodiment of a valve device 210. The fluid reservoir 206 and the valve device 210 can be used, for example, in a fluid injection system, such as the fluid injection system 100 mentioned previously. Figure 2 A perspective view of the fluid reservoir 206 connected to the valve device 210 is shown. Figures 3A-3C A cross-sectional view of the fluid reservoir 206 and the valve device 210 taken along line A-A in Figure 2 Figure 3A A valve member 212 of the valve device 210 in a closed position is shown. Figure 3B A valve member 212 of the valve device 210 in a first open position is shown. Figure 3C A valve member 212 of the valve device 210 in a second open position is shown.

[0033] The fluid reservoir 206 defines an internal reservoir volume 207 that includes the plunger 108. The fluid reservoir 206 can be placed at a fluid injection system such that the plunger 108 is coupled to a drive assembly (e.g., a drive ram) of the fluid injection system. The drive assembly can be configured to move the plunger 108 within the internal reservoir volume 207, such as between a retracted position 208 and an extended position 209. Moving the plunger 108 from the retracted position 208 to the extended position 209 can be used to pressurize fluid within the internal reservoir volume 207. And, moving the plunger 108 from the extended position 209 to the retracted position 208 can be used to draw fluid into the internal reservoir volume 207.

[0034] ​As shown here, a fluid reservoir 206 can be fluidly connected to a valve device 210. The illustrated fluid reservoir 206 includes an inlet port 214 and an outlet port 216. The inlet port 214 and the outlet port 216 can each be in fluid communication with an internal reservoir volume 207. The illustrated valve device 210 includes a valve member 212 and a first port 218, a second port 220, a third port 222, and a fourth port 224. The first port 218 can be fluidly connected with the inlet port 214, and the second port 220 can be fluidly connected with the outlet port 216.

[0035] The valve member 212 of the valve device 210 can be configured to selectively allow fluid to pass through the valve device 210 and to prevent fluid from passing through the valve device 210. The valve member 212 defines a fluid passageway 213. In the illustrated embodiment, the valve member 212 can be configured to selectively allow fluid to pass through the valve device 210 and to prevent fluid from passing through the valve device 210 by selectively placing the fluid passageway 213 in fluid communication and out of fluid communication with two or more of the ports 218, 220, 222, 224.

[0036] Figure 3A A closed position of the valve member 212 is shown. The closed position of the valve member 212 can prevent fluid from passing through the valve device 210 via the fluid passageway 213. In the closed position, as shown for example Figure 3A , the fluid passageway 213 is not in fluid communication with any of the ports 218, 220, 222, 224. In particular, in the closed position Figure 3A , each of the ports 218, 220, 222, 224 is engaged with a solid surface of the valve member 212 that acts to stop fluid from passing through the valve member 212. In certain applications, preventing fluid from passing through the valve device 210 via the fluid passageway 213 in the closed position can mean that fluid is substantially stopped from passing through the fluid passageway 213, although there can be a nominal leakage of fluid through the fluid passageway 213 according to certain manufacturing tolerances at the valve member 212.

[0037] Figure 3B An open position of the valve member 212 is shown. The valve member 212 can be transitioned between the closed position shown for example Figure 3A and the open position shown for example Figure 3B by moving the valve member 212 to adjust the positioning of the fluid passageway 213. The open position of the valve member 212 can allow fluid to pass through the valve device 210 via the fluid passageway 213. In the open position, as shown for example Figure 3B , the fluid passageway 213 is in fluid communication with each of the second port 220 and the fourth port 224. Thus Figure 3Bthe open position allows fluid to pass through the valve device 210 via the fluid passageway 213 from the outlet port 216 of the fluid reservoir 206. In this open position, fluid can flow from the outlet port 216 into the second port 220, through the fluid passageway 213, and exit the valve device 210 at the fourth port 224. At the same time, Figure 3B the open position can prevent fluid from passing through the valve device 210 via the fluid passageway 213 from the inlet port 214 of the fluid reservoir 206.

[0038] Figure 3C A second open position of the valve member 212 is shown. By moving the valve member 212 to adjust the positioning of the fluid passageway 213, the valve member 212 can be transitioned between the closed position shown in Figure 3A the first open position shown in Figure 3B and the second open position shown in Figure 3C Similar to the first open position shown in Figure 3B the second open position of the valve member 212 shown in Figure 3C may allow fluid to pass through the valve device 210 via the fluid passageway 213. In the second open position, for example Figure 3C the fluid passageway 213 is in fluid communication with each of the first port 218 and the third port 222. Figure 3C the second open position thus allows fluid from the inlet port 214 of the fluid reservoir 206 to pass through the valve device 210 via the fluid passageway 213. In this second open position, fluid can flow from the third port 222 through the fluid passageway 213 into the first port 218 and out of the valve device 210 into the inlet port 214. At the same time, Figure 3C the second open position can prevent fluid from passing through the valve device 210 via the fluid passageway 213 from the outlet port 216 of the fluid reservoir 206. Thus, for example Figure 3C the second open position can be configured to allow fluid to enter the fluid reservoir 206 via the fluid passageway 213, while for example Figure 3B the first open position can be configured to allow fluid to exit the fluid reservoir 206 via the fluid passageway 213.

[0039] The valve device 210 includes a valve member coupling 226 configured to transition the valve member 212 between the open positions (e.g., the first open position and the second open position) and the closed position when actuated. The valve member coupling 226 can be coupled to the valve member 212 such that a force applied at the valve member coupling 226 is transmitted to the valve member 212, causing the valve member 212 to move between the open positions and the closed position. For example, when the fluid reservoir 206 is fixed in place at a fluid injection system, the valve member 212 can be in the closed position, for example Figure 3AThe valve member 212 can be coupled to the valve member coupling 226. The valve member coupling 226 can be configured to receive an actuation force from another component, such as a valve actuation coupling, and transmit the actuation force to the valve member 212. The valve member coupling 226 can be configured to couple to the valve member 212. For example, the valve member coupling 226 can be configured to couple to the valve member 212 such that the valve member 212 is disposed within the valve member coupling 226. In this example, the valve member coupling 226 can be configured to receive the actuation force from the valve actuation coupling and transmit the actuation force to the valve member 212. In this example, the valve member coupling 226 can be configured to couple to the valve member 212 such that the valve member 212 is disposed within the valve member coupling 226. In this example, the valve member coupling 226 can be configured to receive the actuation force from the valve actuation coupling and transmit the actuation force to the valve member 212. Figure 3C The valve member coupling 226 can be actuated to transition the valve member 212 from the closed position to an open position, such as the first open position shown in FIG. 3A, when the fluid reservoir 206 is to be filled with fluid, such that fluid can be drawn into the fluid reservoir 206 via the fluid passage 213 through the valve device 210 (e.g., by retracting the plunger 108). The valve member coupling 226 can be actuated to transition the valve member 212 from the fill open position shown in FIG. 3B to another open position, such as the second open position shown in FIG. 3B, when the fluid is to be pressurized and output from the fluid reservoir 206, such that fluid can be output from the fluid reservoir 206 via the fluid passage 213 through the valve device 210 (e.g., by advancing the plunger 108 toward the outlet port 216). The valve member coupling 226 can be actuated to transition the valve member 212 from the open position to the closed position, such as the closed position shown in FIG. 3A, when the fluid reservoir 206 is not in use, to prevent fluid from exiting the fluid reservoir 206. Figure 3C The valve member coupling 226 can be actuated to transition the valve member 212 from the closed position to an open position, such as the first open position shown in FIG. 3A, when the fluid reservoir 206 is to be filled with fluid, such that fluid can be drawn into the fluid reservoir 206 via the fluid passage 213 through the valve device 210 (e.g., by retracting the plunger 108). The valve member coupling 226 can be actuated to transition the valve member 212 from the fill open position shown in FIG. 3B to another open position, such as the second open position shown in FIG. 3B, when the fluid is to be pressurized and output from the fluid reservoir 206, such that fluid can be output from the fluid reservoir 206 via the fluid passage 213 through the valve device 210 (e.g., by advancing the plunger 108 toward the outlet port 216). The valve member coupling 226 can be actuated to transition the valve member 212 from the open position to the closed position, such as the closed position shown in FIG. 3A, when the fluid reservoir 206 is not in use, to prevent fluid from exiting the fluid reservoir 206. Figure 3B The valve member coupling 226 can be actuated to transition the valve member 212 from the closed position to an open position, such as the first open position shown in FIG. 3A, when the fluid reservoir 206 is to be filled with fluid, such that fluid can be drawn into the fluid reservoir 206 via the fluid passage 213 through the valve device 210 (e.g., by retracting the plunger 108). The valve member coupling 226 can be actuated to transition the valve member 212 from the fill open position shown in FIG. 3B to another open position, such as the second open position shown in FIG. 3B, when the fluid is to be pressurized and output from the fluid reservoir 206, such that fluid can be output from the fluid reservoir 206 via the fluid passage 213 through the valve device 210 (e.g., by advancing the plunger 108 toward the outlet port 216). The valve member coupling 226 can be actuated to transition the valve member 212 from the open position to the closed position, such as the closed position shown in FIG. 3A, when the fluid reservoir 206 is not in use, to prevent fluid from exiting the fluid reservoir 206. Figure 3A The valve member coupling 226 can be actuated to transition the valve member 212 from the closed position to an open position, such as the first open position shown in FIG. 3A, when the fluid reservoir 206 is to be filled with fluid, such that fluid can be drawn into the fluid reservoir 206 via the fluid passage 213 through the valve device 210 (e.g., by retracting the plunger 108). The valve member coupling 226 can be actuated to transition the valve member 212 from the fill open position shown in FIG. 3B to another open position, such as the second open position shown in FIG. 3B, when the fluid is to be pressurized and output from the fluid reservoir 206, such that fluid can be output from the fluid reservoir 206 via the fluid passage 213 through the valve device 210 (e.g., by advancing the plunger 108 toward the outlet port 216). The valve member coupling 226 can be actuated to transition the valve member 212 from the open position to the closed position, such as the closed position shown in FIG. 3A, when the fluid reservoir 206 is not in use, to prevent fluid from exiting the fluid reservoir 206.

[0040] The valve member coupling 226 can define a structure adapted to couple to another component, such as a valve actuation coupling, that receives an actuation force from the component and transmits the actuation force to the valve member 212. The illustrated embodiment of the valve member coupling 226 includes a first side wall 227, a second side wall 228, and a back wall 229. The second side wall 228 is opposite the first side wall 227, and the back wall 229 extends between the first side wall 227 and the second side wall 228. Together, the first side wall 227, the second side wall 228, and the back wall 229 can define a fitting 230. The fitting 230 can be configured to be complementary to and couple with another component. For example, the fitting 230 can be configured to be complementary to and couple with a valve actuation coupling. In this example, the valve actuation coupling can be received between the first side wall 227 and the second side wall 228 of the valve member coupling 226.

[0041] Figure 4 and 5 The valve device 210 is shown coupled with an embodiment of a valve actuation device 235. Figure 4 The valve device 210 is shown coupled with an embodiment of a valve actuation device 235. Figure 2 and 3A The valve device 210 is shown coupled with an embodiment of a valve actuation device 235. Figure 5 is a cross-sectional view of the valve device 210 coupled to the valve actuation device 235 taken along line B-B in FIG. 3C. The valve actuation device 235 can be used to actuate the valve device 210, thereby causing the valve member 212 to transition between the open positions (e.g., the first open position and the second open position) and the closed position. Figure 4 is a cross-sectional view of the valve device 210 coupled to the valve actuation device 235 taken along line B-B in FIG. 3C. The valve actuation device 235 can be used to actuate the valve device 210, thereby causing the valve member 212 to transition between the open positions (e.g., the first open position and the second open position) and the closed position.

[0042] like Figure 4 As shown, a fluid reservoir 206 with an attached valve device 210 can be secured to a sleeve 232 of a fluid injection system. Specifically, the fluid reservoir 206 is typically secured to the sleeve 232 in a manner that couples a plunger within the fluid reservoir 206 to a drive pushrod of a drive assembly of the fluid injection system. Due to manufacturing tolerances of the fluid reservoir 206 and the attached valve device 210, the precise position of the valve device 210 and the associated valve member coupling 226 after the plunger is coupled to the drive pushrod can change each time the fluid reservoir is secured to the sleeve 232. To account for this variability in the position of the valve device 210 and the associated valve member coupling 226, the valve actuator 235 can be configured to move in a direction that allows the valve actuator 235 to couple to the valve device 210 at a plurality of different valve device 210 positions. Thus, the valve actuator 235 can accommodate the variable position of the valve assembly 210, thereby compensating for any misalignment with the valve assembly 210 once the fluid reservoir 206 has been secured in place.

[0043] The valve actuator 235 may include a valve actuator coupler 236. The valve actuator coupler 236 is configured to couple to the valve device 210. Specifically, the valve actuator coupler 236 may couple to the valve member coupler 226. Thus, the valve actuator coupler 236 forms a complementary fitting to the fitting 230 formed by the valve member coupler 226. In the illustrated embodiment, the valve actuator coupler 236 includes an actuator arm 237 coupled to the valve member coupler 226. Specifically, the actuator arm 237 may be received within the fitting 230 of the valve member coupler 226 formed between the first sidewall 227 and the second sidewall 228. In other embodiments, the configuration may be reversed from that shown, such that the fitting 230 of the valve member coupler 226 may be received within the actuator arm 237, which defines a receptacle formed by two sidewalls and a rear wall.

[0044] The valve actuator 235 may further include a drive mechanism 240. The drive mechanism 240 may be coupled to the valve actuation coupling 236, and the drive mechanism 240 may provide power to the valve actuation coupling 236, thereby actuating the valve member coupling 226. Thus, the valve actuation coupling 236 may move with the drive mechanism 240 to actuate the valve member coupling 226, thereby transitioning the valve member 212 between the open position and the closed position. For example, at least a portion of the drive mechanism 240 may be configured to rotate about a drive axis 241 and, in turn, provide rotational power to the valve actuation coupling 236, thereby actuating the valve member coupling 226.

[0045] To provide power to actuate the valve member coupling 226, a power source 242 can be included in the fluid injection system. The power source 242 can be coupled to the drive mechanism 240. As such, the power source 242 can be configured to provide power to drive (e.g., rotatably drive) the drive mechanism 240 and actuate the valve member coupling 226 to transition the valve member 212 between the open position and the closed position. The power source 242 can be in the form of various suitable sources, including various types of motors having a size and power generating capacity suitable for inclusion in the fluid injection system.

[0046] To control the power source 242, the fluid injection system can also include a controller. In some embodiments, the controller can be configured to control the transition of the valve member 212 between the open position and the closed position by controlling the power provided by the power source 242 to the drive mechanism 240. As one example, the controller can be a processor-based controller as described in reference to the control panel 110. Figure 1 The control panel 110 shown and described, the controller can include one or more processors for executing computer-readable instructions stored in a non-transitory storage medium to enable the controller to receive inputs and, in response, generate and send output commands to cause the power source 242 to open / close and / or adjust the amount of power provided to the drive mechanism 240. For example, the controller can receive a valve open instruction as an input as a result of a user inputting a valve open request at the control panel 110. And, in response, the controller can generate and send an output command to the power source 242 to cause the power source 242 to provide an amount of power to the drive mechanism 240 sufficient to cause the valve member 212 to transition from the closed position to the open position or from one open position to another open position. In some embodiments, the controller can receive input commands in the form of data from one or more other injection system components (e.g., the drive assembly). And, in response to data from one or more other injection system components being at a predetermined threshold (e.g., the drive assembly being at a predetermined position or cycle), the controller can generate and send an output command to the power source 242 to cause the power source 242 to provide an amount of power to the drive mechanism 240 sufficient to cause the valve member 212 to transition from the closed position to the open position or from one open position to another open position.

[0047] It should be noted that, as previously described, in order to accommodate the variable positions of the valve device 210 and the associated valve member coupling 226, the valve actuator 235 can be configured to move as needed to couple to the valve device 210 at a plurality of different valve device 210 positions. In the illustrated embodiment, the valve actuator coupling 236 of the valve actuator 235 is movable independently of the drive mechanism 240 and relative to the valve member coupling 226 to couple the valve actuator coupling 236 to the valve member coupling 226. Thus, the valve actuator coupling 236 is movable independently of the drive mechanism 240 to couple to the valve member coupling 226, and is movable with the drive mechanism 240 to actuate the valve member coupling 226, thereby transitioning the valve member 212 between the open position and the closed position.

[0048] More particularly, in the illustrated embodiment, the valve actuation coupling 236 is movable independently of the drive mechanism 240 in a direction that allows the valve actuation coupling 236 to be aligned with the valve member coupling 226. In many fluid injection system applications, misalignment between the valve member coupling 226 and the valve actuation coupling 236 can occur along the Figure 5 The valve actuation coupling 236 is movable in the direction 244 shown. Thus, in the example described herein, the valve actuation coupling 236 is movable independently of the drive mechanism 240 in the direction 244 so as to better align the valve member coupling 226 and the valve actuation coupling 236 along the direction 244. In the embodiment shown, the valve actuation coupling 236 is movable independently of the drive mechanism 240 in the direction 244 away from the drive axis 241. In this way, the valve member coupling 226 can be in a position offset from the drive axis 241, and the valve actuation coupling 236 can be moved independently of the drive mechanism 240 to a position offset from the drive axis 241. This movement of the valve actuation coupling 236 can be relative to the valve member coupling 226. Specifically, for example, Figure 5 As shown, the valve actuation coupling 236 is movable relative to the first and second sidewalls 227, 228 independently of the drive mechanism 240. This movement of the valve actuation coupling 236 can result in a greater surface area of ​​the actuation arm 237 being positioned within the fitting 230 defined by the valve member coupling 226.

[0049] In some embodiments, it may be useful to limit movement in one or more directions of the valve actuation coupler 236. That is, it may be useful to limit movement of the valve actuation coupler 236 in one or more directions other than the directions in which the valve actuation coupler 236 is movable independently of the drive mechanism 240 (e.g., direction 244) in order to better align the valve member coupler 226 and the valve actuation coupler 236.

[0050] To limit the movement of the valve actuation coupling 236 in one or more directions, the illustrated embodiment of the valve actuation device 235 includes a restriction plate 246. The restriction plate 246 may define a hole 247 extending through the restriction plate 246. Figure 5 As shown, the valve actuation coupling 236 can extend through the hole 247 of the restricting plate 246. The hole 247 can have a first dimension and a second dimension perpendicular to the first dimension. In the illustrated embodiment, the first dimension extends parallel to the direction 244, while the second dimension extends perpendicular to the direction 244. In this way, the valve actuation coupling 236 can move independently of the drive mechanism 240 along the first dimension. The second dimension can be sized to limit the movement of the valve actuation coupling 236 along the second dimension independently of the drive mechanism 240 to less than the movement along the first dimension. In one example, the second dimension can be sized to substantially prevent the valve actuation coupling 236 from moving independently of the drive mechanism 240 along the second dimension. Therefore, this embodiment of the restricting plate 246 can be configured to allow the valve actuation coupling 236 to move independently of the drive mechanism 240 in the direction aligned with and coupled to the valve member coupling 226 (e.g., direction 244), but constrain the valve actuation coupling 236 to have less movement in one or more other directions. Conversely, in another embodiment, for example, where the valve actuation coupler 236 is movable along a second dimension independently of the drive mechanism 240, the first dimension can be sized to restrict the movement of the valve actuation coupler 236 along the first dimension to be less than the movement along the second dimension independently of the drive mechanism 240. In such an example, the first dimension can be sized to substantially prevent movement of the valve actuation coupler 236 along the first dimension independently of the drive mechanism 240. Thus, this alternative embodiment of the restrictor plate 246 can be configured to allow the valve actuation coupler 236 to move independently of the drive mechanism 240 in a direction aligned with and coupled to the valve member coupler 226 (e.g., perpendicular to the direction 244), but constrain the valve actuation coupler 236 to less movement in one or more other directions.

[0051] Figure 6 2 shows an exploded perspective view of the valve actuator 235. As described, the valve actuator 235 can include a valve actuator coupling 236 and a drive mechanism 240. The components comprising the valve actuator 235 and the drive mechanism 240 can allow the valve actuator coupling 236 to move independently of the drive mechanism 240 to couple to the valve member coupling, and to move with the drive mechanism 240 to actuate the valve member coupling 226.

[0052] The drive mechanism 240 can include a drive shaft 248 and a transfer connector 250. The drive shaft 248 includes a drive shaft coupling 252. In the illustrated embodiment, the drive shaft coupling 252 includes a first slot 253 defined at an end of the drive shaft 248. The transfer connector 250 includes a first transfer coupling 254 and a second transfer coupling 256. In the illustrated embodiment, the first transfer coupling 254 includes a first extended flange extending from a base 251 of the transfer connector 250, and the second transfer coupling 256 includes a second extended flange extending from an opposite side of the base 251 of the transfer connector 250.

[0053] As shown, the drive shaft 248 can be coupled to the valve actuation coupling 236 via the transfer connector 250. The transfer connector 250 is positioned between the drive shaft 248 and the valve actuation coupling 236. In particular, the drive shaft coupling 252 can be complementary to and coupled with the first transfer coupling 254, and the valve actuation coupling 236 can be complementary to and coupled with the second transfer coupling 256. The valve actuation coupling 236 can include a second slot 238 defined at an end of the valve actuation coupling 236. The second slot 238 can be at an end of the valve actuation coupling 236 opposite the end from which the actuation arm 237 extends. The second extended flange of the second transfer coupling 256 can be received at the second slot 238, and the first extended flange of the first transfer coupling 254 can be received at the first slot 253.

[0054] In the illustrated embodiment, the transfer connector 250 can enable the valve actuation coupling 236 to move independently of the drive mechanism 240 and to move with the drive mechanism 240. In particular, the illustrated example can be configured such that, in operation, the drive shaft 248 can rotate about the drive shaft axis 241 and rotatably drive the transfer connector 250 via the first slot 253 and the first extended flange of the first transfer coupling 254. The transfer connector 250 can transmit this rotational drive force to the valve actuation coupling 236 via the second slot 238 and the second extended flange of the second transfer coupling 256. This can enable the valve actuation coupling 236 to move (e.g., rotationally) with the drive mechanism 240 to actuate the valve member coupling 226 to transition the valve member 212 between the open and closed positions. At the same time, the illustrated example can be configured such that, in operation, the valve actuation coupling 236 can move relative to the transfer connector 250. In particular, the valve actuation coupling 236 can move relative to the second transfer coupling 256 via the second slot 238 and the second extended flange of the second transfer coupling 256. This can enable the valve actuation coupling 236 to move independently of the drive mechanism 240 (e.g., in a direction perpendicular to the drive shaft axis, such as direction 244) to couple the valve actuation coupling 236 to the valve member coupling 226.

[0055] As one example, the valve actuation device 235 can include a cross-slip coupling. The cross-slip coupling can be used to couple the valve actuation coupling 236 to the drive mechanism 240. In particular, the cross-slip coupling can be configured to enable the valve actuation coupling 236 to move independently of the drive mechanism 240 to couple the valve actuation coupling 236 to the valve member coupling 226, and to move with the drive mechanism 240 to actuate the valve member coupling 226 to transition the valve member 212 between the open and closed positions. In such an example, the cross-slip coupling can be formed by the transfer connector 250, and surfaces of the drive shaft coupling 252 and the valve actuation coupling 236 that engage the transfer connector 250. The cross-slip coupling can thus be configured to allow the drive mechanism 240 to drive the valve actuation coupling 236, and also to allow the valve actuation coupling 236 to move independently of the drive mechanism (e.g., independently of the drive shaft 248, such as in a direction perpendicular to the drive shaft line 241 (e.g., direction 244)).

[0056] In the illustrated embodiment, the drive mechanism 240 additionally includes a rotatable wheel 260 and a link member 262. The link member 262 can be coupled to the rotatable wheel 260, for example, at a receptacle 261 defined at the rotatable wheel 260. The rotatable wheel 260 can be coupled to the drive shaft 248, for example, at an end of the drive shaft 248 opposite the end of the drive shaft 248 having the drive shaft coupling 252. The rotatable wheel 260 and the link member 262 can be configured to exert a force on the drive shaft 248 to drive the drive shaft 248, and thereby move the drive mechanism 240 to actuate the valve member coupling 226. In particular, the link member 262 can be coupled to and receive a force from the power source 242. The link member 262 can transfer the force to the rotatable wheel 260. In this way, the link member 262 can be configured to rotatably drive the rotatable wheel 260 to move the drive mechanism 240 to actuate the valve member coupling 226. Other embodiments can implement varying mechanisms to exert a force on the drive shaft 248 to drive the drive shaft 248, and thereby move the drive mechanism 240 to actuate the valve member coupling 226.

[0057] In some embodiments, one or more components can be included to facilitate the described operation of the valve actuation device 235. For example, the valve actuation device 235 can include one or more bearings 264, for example, included at one or more locations where relative rotation between components can occur. In the illustrated embodiment, a bearing 264 is included between the drive shaft 248 and the end plate 266. This bearing 264 can be at an end of the drive shaft 248, for example, at an end of the drive shaft 248 that is engaged with the rotatable wheel 260, and this bearing 264 can function to secure the rotatable drive shaft 248 to the end plate 266. In the illustrated embodiment, another bearing 264 is included between the drive shaft 248 and the mounting block 268. This bearing 264 can be at a portion of the drive shaft 248 to engage with the drive shaft coupling 252, and this bearing 264 can function to secure the rotatable drive shaft 248 to the mounting block 268. The end plate 266 and / or the mounting block 268 can at least partially form a housing of the valve actuation device 235, within which one or more components of the valve actuation device 235 can be located. The end plate 266 and / or the mounting block 268 can also provide one or more surfaces for securing certain components of the valve actuation device 235.

[0058] Figure 7 A flowchart illustrating an embodiment of a method 700 of coupling a valve actuation device to a valve device and actuating the valve device is shown. The valve actuation device involved in the method 700 can have one or more (e.g., all) features as disclosed herein with respect to the valve actuation device 235. The valve device involved in the method 700 can have one or more (e.g., all) features as disclosed herein with respect to the valve device 210.

[0059] At step 710, the method 700 includes placing a fluid reservoir at a fluid injection system. The fluid reservoir involved in the method 700 can have one or more (e.g., all) features as disclosed herein with respect to the fluid reservoir 206. For example, the fluid reservoir can be placed at the fluid injection system such that a plunger (e.g., the plunger 108) is coupled to a drive ram of a drive assembly of the fluid injection system. This can include placing the fluid reservoir at a sleeve (e.g., the sleeve 232) of the fluid injection system. Placing the fluid reservoir at the fluid injection system can result in a valve device (e.g., the valve device 210) connected to the fluid reservoir being positioned at a location that can vary with placement of the fluid reservoir at the fluid injection system. Depending on the embodiment of the fluid injection system, in some cases, placing the fluid reservoir at the fluid injection system can include placing the fluid reservoir in the fluid injection system, such as in a sleeve of the fluid injection system.

[0060] At step 720, the method 700 includes coupling a valve actuation device (e.g., the valve actuation device 235) to a valve device (e.g., the valve device 210 coupled to the fluid reservoir). For example, the valve actuation device can include a valve actuation coupling coupled to a drive mechanism of the valve actuation device. In such an example, coupling the valve actuation device to the valve device can include coupling the valve actuation coupling of the valve actuation device to a valve member coupling of the valve device. In some cases, the valve device can not initially be aligned with the valve actuation coupling due to placement of the fluid reservoir at the fluid injection system. As such, step 720 can include moving the valve actuation coupling in a direction that aligns the valve actuation coupling with the valve member coupling independent of the drive mechanism of the valve actuation device, such that the valve actuation coupling can be coupled to the valve member coupling. For example, the drive mechanism of the valve actuation device can be configured to rotate about a drive axis, and moving the valve actuation coupling can include moving the valve actuation coupling in a direction away from the drive axis (e.g., in a direction perpendicular to and away from the drive axis) independent of the drive mechanism of the valve actuation device.

[0061] At step 730, the method 700 includes actuating the valve device. For example, actuating the valve device can include moving the valve actuation coupling of the valve actuation device coupled to the drive mechanism to actuate the valve member coupling of the valve device, thereby transitioning the valve member of the valve device (e.g., the valve member 212) between an open position and a closed position. For example, the valve device can be actuated to transition the valve member from the closed position to the open position prior to advancing the plunger within the fluid reservoir to pressurize the fluid within the fluid reservoir. The valve device can also be actuated to transition the valve member from one open position (e.g., for fluid output / delivery) to another open position (e.g., for fluid filling into the fluid reservoir).

[0062] Various non-limiting example embodiments have been described. It should be understood that appropriate alternatives are possible without departing from the scope of the examples described herein. These and other examples are within the scope of the following claims.
