Description

[0001] This invention relates to a hydraulic cartridge valve. In particular, it relates to a bidirectional hydraulic cartridge valve with throttling and blocking functions, especially a servo and control cartridge valve. Furthermore, the invention includes valve devices having the hydraulic cartridge valve according to the invention, and hydraulic equipment having valve devices.

[0002] Hydraulic cartridge valves (especially seated two-way hydraulic cartridge valves), also known as logic valves, are known in the prior art and are widely used in hydraulic control technology as pressure valves, directional valves, or check valves.

[0003] For example, a seated hydraulic cartridge valve is described in document EP 3 514 418 A1. This classic two-way hydraulic cartridge valve (or logic valve) of this seated design includes a sleeve that can be introduced into a valve block and a shut-off element. The upper region of the sleeve is fixedly connected to the valve block. The sleeve has a lower region opposite the upper region, wherein the lower region has a front opening in its front end and forms an insert ring, wherein the insert ring can be introduced into a receiving hole in the valve block and its outer circumference has an insert ring diameter. A jacket is formed between the upper and lower regions of the sleeve, wherein the jacket has a plurality of radial openings separated by a web, and the shut-off element is arranged in the sleeve. The shut-off element is movable between an open position and a shut-off position, wherein in the open position the fluid connection between the front opening and the radial openings is released, and in the shut-off position the fluid connection between the front opening and the radial openings is shut off. Through radial openings formed in the jacket wall of the sleeve, typically designed as transverse bores or semi-circular milled cuts, fluid is guided from port A through the radial opening to port B or vice versa when the shut-off element is in the open position. A disadvantage of this design is that when a cartridge valve is introduced into the valve block, the radial openings of the sleeve may be arranged such that the radial openings are not optimally oriented for fluid flow relative to port B. This can lead to turbulence and / or friction at the radial openings, resulting in pressure loss. To mitigate these disturbances, additional directional mechanisms are required, which complicates the design and manufacture of cartridge valves, making it both time-consuming and expensive. Alternatively, the user must position the cartridge valve during installation to achieve maximum flow. This further complicates installation and / or maintenance. Furthermore, the radial openings may have through-holes or diameters that cannot guide fluid supplied via port B or port A at a specific pressure without reducing pressure, potentially leading to increased pressure loss and therefore higher-than-expected energy loss.

[0004] Therefore, the technical objective of this invention is to at least partially overcome the known disadvantages in the prior art in order to minimize the pressure loss of hydraulic cartridge valves.

[0005] This task is solved by the subject matter of the independent patent claims, particularly by a hydraulic cartridge valve and a valve device. Advantageous embodiments of the invention are described in the independent claims and the following description. The scope of protection is defined by the appended claims.

[0006] According to a first aspect, the present invention relates to a hydraulic cartridge valve for a valve block. The hydraulic cartridge valve includes a sleeve capable of being introduced into a valve block and a shut-off element. The sleeve includes a first end region. The first end region is connectable to the valve block. The sleeve includes a second end region opposite to the first end region. The second end region has a front opening in its front end portion. A jacket with outer and inner sides is formed between the first and second end regions of the sleeve. The jacket of the sleeve has a plurality of jacket through-holes separated by a jacket web. The shut-off element is movably arranged in the sleeve. Furthermore, the shut-off element is movable between a first position and a second position. In the first position of the shut-off element, the fluid connection between the front opening and the jacket through-holes is released, and in the second position, the fluid connection between the front opening and the jacket through-holes is blocked. The hydraulic cartridge valve is characterized in that the jacket through-holes (in a certain direction) extend along the jacket from the first end region to the second end region and form a through-hole height, the aspect ratio of the jacket through-holes being at least 3:1.

[0007] This invention is based on the understanding that there is a need for a hydraulic cartridge valve characterized by simplified installation while improving flow conditions and fluid pressure, without requiring the cartridge valve to be oriented to port B in the control block.

[0008] Advantageously, through this invention, particularly through the design of the jacketed through-hole, no intentional orientation is required when installing the cartridge valve into the valve block. The jacketed through-hole improves the flow through the hydraulic cartridge valve, thereby reducing pressure loss by 40% to 50% compared to comparable prior art, even with hydraulic cartridge valves of the same nominal valve size.

[0009] Advantageous implementations and improvements are derived from the dependent claims and the description with reference to the accompanying drawings.

[0010] In a preferred embodiment, the jacket through-hole has an aspect ratio greater than 4:1. Advantageously, by increasing the aspect ratio, especially 4:1, the flow rate becomes more independent of the orientation of the hydraulic cartridge valve relative to port B in the control block. However, embodiments known in the art have shown that increasing the number of through-holes worsens the flow rate because this also increases the number of webs. It has been determined that, according to the embodiments, using jacket through-holes with aspect ratios between 3:1 and 5:1, primarily in the range of 4:1, achieves optimal flow rates. However, practical applicability is not limited to using ratios greater than 3:1 to 5:1 in the preferred embodiment.

[0011] In one embodiment of the invention, the width of the jacket web is constant along its extension from the outer side of the jacket to the inner side. Advantageously, fluid flow is guided, and flow conditions are improved, thereby reducing pressure loss.

[0012] In a further embodiment, the width of the jacket through-hole gradually decreases as it extends from the outside of the jacket to the inside. Advantageously, the width of the jacket through-hole gradually tapers from the outside of the jacket to the inside. Therefore, improved fluid guidance is advantageously achieved, and thus improved fluid flow is realized.

[0013] In a further embodiment, the width of the jacket through-hole on the inner side of the jacket is at least 20% to 90%, preferably 60% to 80%, and particularly preferably 73% to 80% of the width of the jacket through-hole on the outer side of the jacket. Hydraulic cartridge valves known in the prior art have radial openings of constant width extending from the outer side to the inner side of the jacket. With the design according to the invention, fluid flow is guided to a greater extent in every case, thereby achieving an improvement in fluid flow due to a reduction in pressure loss.

[0014] In a further embodiment, at least eight, preferably ten or more, jacket through-holes are formed adjacent to each other in the circumferential direction of the jacket. Furthermore, the total width of the jacket web separating the jacket through-holes in the circumferential direction is at most 25%, preferably 20%, of the outer circumference of the jacket. The design of the present invention with at least eight, preferably ten or more, jacket through-holes provides greater independence in the orientation of the jacket through-holes relative to the corresponding ports in the valve block. Therefore, it is not necessary to orient the jacket through-holes when installing the hydraulic cartridge valve in the valve block. Consequently, a complex orientation mechanism is not required, which means that the hydraulic cartridge valve can be installed efficiently and economically. The number of jacket through-holes can be selected according to the inner and outer diameters of the cylinder jacket, especially according to its construction. In particular, the number of jacket through-holes can be determined by the width of the jacket web and therefore by their strength in relation to the inner and outer diameters of the cylinder jacket.

[0015] In a further embodiment, the total width of the jacket through-hole in the jacket is at least 75% of the outer circumference of the jacket, preferably 80% of the outer circumference of the jacket. Advantageously, this ensures that the jacket through-hole area is sufficiently large relative to the fluid supply port, and that fluid is guided into the hydraulic cartridge valve with the lowest possible pressure loss.

[0016] In a further embodiment, the jacket through-holes are designed to taper in a trapezoidal manner as they extend from the outside to the inside of the jacket. The trapezoidal design of the jacket through-holes offers advantages in fluid technology, for example, compared to a rectangular design. The trapezoidal design, which narrows from the outside to the inside, facilitates fluid flow. Furthermore, the trapezoidal shape is a technically efficient and economical variation of the gradually narrowing through-holes.

[0017] In a further embodiment, the shut-off element has a sealing surface for engaging with a complementary sealing surface formed in the sleeve to block fluid connection in a second position through an interlocking seal. In some designs, the sealing surface is implemented as an edge that forms a complementary seal with the sealing surface of the shut-off element. A leak-free seal is achieved through the sealing surfaces to prevent fluid from passing through the shut-off element in the second position (shut-off position).

[0018] In a further embodiment, the closing element has a tapered extension, starting from the sealing surface of the closing element having a first diameter, passing through a second diameter at the middle of the extension, and then to a third diameter. The first and third diameters of the closing element can each have different diameters. Advantageously, the tapered extension of the closing element creates additional flow space within the hydraulic cartridge valve between the closing element and the valve sleeve. Therefore, improved fluid flow can be achieved when fluid flows through the hydraulic cartridge valve. Furthermore, the tapered design of the closing element reduces turbulence, thereby better guiding the fluid to the corresponding opening of the hydraulic cartridge valve.

[0019] In a further embodiment, the sleeve has a fastening mechanism designed to accommodate the sleeve within a control cover of a control block for controlling a hydraulic cartridge valve, particularly for securing the sleeve. The sleeve is fixedly connected to the control cover, for example, axially and radially, by the fastening mechanism. The sleeve is also fixedly connected to the control block or cartridge cavity via its connection to the control cover. In one embodiment, the sleeve can be screwed to the control cover. Thus, all forces are absorbed within the cover, and the load on the web is reduced. The width of the jacket through-hole can therefore be advantageously maximized.

[0020] A second aspect of the invention includes a valve device having a valve block and a hydraulic cartridge valve having a sleeve that can be introduced into the valve block and a closing element according to any one of the preceding claims. The valve block has a stepped receiving port in which the hydraulic cartridge valve is disposed. The valve block has a port A corresponding to a front opening and a port B freely corresponding to a jacket through-hole. Since the jacket through-hole can freely correspond to port B, complex orientation of the jacket through-hole is unnecessary.

[0021] In one embodiment according to the second aspect, the valve block may be configured to have an additional port, such as a C port, etc.

[0022] In a further embodiment of the second aspect of the invention, the through-hole height of the jacket through-hole is at least 90% of the standard borehole range of port B. The borehole range of port B has a specific height according to ISO 7368. The through-hole height of the jacket through-hole is at least 90% of the borehole range. This reduces turbulence at the opening of the jacket through-hole compared to the prior art, improves the flow rate of fluid entering the hydraulic cartridge valve, and reduces pressure loss. Depending on the design, the through-hole height of the jacket through-hole can also depend on the standard borehole range of other ports.

[0023] In a further embodiment of the second aspect of the invention, the front opening has a first diameter, which preferably corresponds to at least 90% of the second diameter of the sleeve that can be introduced. The second diameter of the sleeve that can be introduced is formed in the region of the sleeve received in port A. Thus, the second diameter describes the outer diameter of the region of the sleeve that can be introduced and received by port A. By screwing in the screw-fitted (axially fixed) valve sleeve, a shoulder is no longer needed in the valve block bore. Therefore, the front opening on the valve sleeve can be implemented to be much larger than the standard diameter of port A specified in relevant standards.

[0024] Another aspect of the invention includes a hydraulic device. This hydraulic device includes at least one hydraulic drive component and a valve device for controlling and / or switching and / or blocking the hydraulic drive component according to any one of the claims of the second aspect of the invention.

[0025] The above-described embodiments and improved embodiments can be combined arbitrarily with each other, as long as they are reasonable. Other feasible embodiments, improved embodiments, and implementations of the present invention also include combinations of inventive features described in the above or following reference embodiments that are not explicitly mentioned. In particular, those skilled in the art will also add various aspects as improvements or supplements to the corresponding basic forms of the present invention.

[0026] The present invention will now be explained in detail with reference to the embodiments given in the schematic drawings. Attached image description:

[0027] Figure 1 A schematic diagram of one embodiment of the hydraulic cartridge valve according to the present invention is shown;

[0028] Figure 2 A schematic diagram of another embodiment of the hydraulic cartridge valve according to the present invention is shown, wherein the sleeve is shown in detail;

[0029] Figure 3 A schematic diagram of an embodiment of the sleeve of the hydraulic cartridge valve according to the present invention is shown in top view.

[0030] The accompanying drawings are intended to provide a further understanding of the embodiments of the invention. They illustrate the embodiments and serve to explain the principles and solutions of the invention in conjunction with the explanatory text. Other embodiments and many of the described advantages are derived from the drawings. Elements in the drawings are not necessarily shown to scale.

[0031] In the accompanying drawings, unless otherwise specified, identical, functionally identical, and actionable elements, features, and components are each given the same reference numerals.

[0032] Figure 1 A schematic diagram of one embodiment of the hydraulic cartridge valve according to the present invention is shown. Reference numeral 100 describes the hydraulic cartridge valve. The hydraulic cartridge valve 100 is shown as being inserted into a valve block 10 (indicated by dashed lines). The hydraulic cartridge valve 100 has a sleeve 110 that can be introduced into the valve block 10. Furthermore, the hydraulic cartridge valve 100 has a shut-off element 130. The shut-off element 130 is movably arranged in the sleeve 110. The sleeve 110 has a first end region 111. Furthermore, the sleeve 110 has a second end region 112 opposite to the first end region 111. The second end region 112 has a front opening 114 in a front end portion 113. The front end portion 113 has a diameter for receiving an A port having a standard diameter. In one embodiment, the front end portion 113 has a geometry optimized for flow rate relative to the diameter at the A port.

[0033] A sleeve 110 forms a jacket 117 between a first end region 111 and a second end region 112. The jacket 117 has an outer side and an inner side. The jacket 117 of the sleeve 110 has a plurality of jacket through-holes 119 spaced apart by a jacket web 118. The jacket through-holes 119 represent fluid conduction openings or connections between the outer and inner sides of the jacket 117 of the sleeve 110. The jacket web 118 forms a partition between two adjacent jacket through-holes 119.

[0034] A shut-off element 130, movably arranged within the sleeve 110, is movable between a first position and a second position. In the first position, the fluid connection between the front opening 114 and the jacket through-hole 119 is released. In this position, fluid can flow from port A to port B or vice versa. In the second position, the fluid connection between the front opening 114 and the jacket through-hole 119 is blocked. In this position, fluid cannot flow from port A to port B or vice versa.

[0035] In one embodiment, the shut-off element 130 has a tapered extension. Specifically, the shut-off element 130 includes a first diameter designed to form a fluid seal together with a sealing surface 120a designed complementary to the sealing surface 120a within the sleeve 110. The shut-off element includes a second diameter in the middle section of its extension, designed to cause the shut-off element 130 to form a tapered shape. Specifically, the second diameter is smaller than the first diameter used for the fluid seal. Continuing from the middle section of the extension, the shut-off element 130 includes a third diameter larger than the second diameter. In one design, the first and third diameters of the shut-off element 130 may be different. The tapered design of the shut-off element 130 creates a larger cross-sectional area within the sleeve 110, thereby achieving improved flow and minimizing pressure loss.

[0036] The jacket through-holes 119 in the jacket 117 are designed to taper gradually in a trapezoidal manner as they extend from the outside to the inside of the jacket. In one embodiment, the width of the jacket through-holes 119 gradually decreases, particularly as they extend from the outside to the inside of the jacket 117.

[0037] In one embodiment, the valve block 10 has a stepped receiving port 11 in which the hydraulic cartridge valve 100 is received and disposed. The stepped receiving port 11 accommodates a diameter jump in the outer diameter of the sleeve 110. The stepped receiving port 11 and the diameter jump allow fluid from the sleeve to be introduced into the valve block 10 in a sealed manner.

[0038] In another embodiment, the sleeve 110 is fixedly connected to the control cover 132. The sleeve 110 is securely fixed to the control cover 132, for example, by screwing the sleeve into the control cover 132. An axial and radial connection is established between the sleeve 110 and the control cover 132. Through the fixed connection between the sleeve 110 and the control cover 132, the sleeve 110 is fixedly connected to a control block (not shown) or a cartridge cavity. By connecting the sleeve 110 to the control cover 132, all forces are absorbed within the control cover 132.

[0039] Figure 2A schematic diagram of another embodiment of the hydraulic cartridge valve according to the present invention is shown, in which the sleeve is shown in detail. Figure 2 In the design of the jacket through-hole 119 and jacket web 118, the fluid is visible in half-section of the hydraulic cartridge valve 110. In the jacket 117, the jacket through-hole 119 is designed to taper gradually in a trapezoidal manner along its extension from the outer side to the inner side of the jacket. Fluid is guided into the interior of the sleeve 110 via the trapezoidal jacket through-hole 119. In a preferred embodiment, the trapezoidal cross-section of the jacket through-hole 119 tapers gradually from the outer side to the inner side of the jacket. The width of the jacket web remains constant. The width of the jacket through-hole 119 decreases accordingly. Therefore, fluid is introduced into the hydraulic cartridge valve 100 from the larger cross-section at port B. Alternatively, fluid is guided from port A and from a smaller cross-section within the hydraulic cartridge valve 100 to port B.

[0040] In one embodiment of the hydraulic cartridge valve 100, a jacket through-port 119 extends along the jacket 117 from a first end region 111 to a second end region 112, and forms the through-port height. In one embodiment, the jacket through-port 119 has an aspect ratio of at least 3:1, preferably 4:1. Advantageously, to achieve optimal fluid flow at the corresponding pressure, the jacket through-port 119 does not need to be precisely oriented relative to the orifice of port B. The through-port height of the jacket through-port 119 ensures that fluid at the necessary pressure is either introduced into or can flow out of the hydraulic cartridge valve 100 via the jacket through-port 119. No manual placement by the user and / or the use of a placement mechanism is required. Furthermore, cartridge valves known in the prior art typically only have circular orifices to realize the jacket through-port. However, as the number of circular orifices increases, higher pressure loss occurs. To minimize pressure loss, four approximately square radial openings are provided, designed to minimize pressure loss. However, due to the limited number of radial openings, these radial openings are no longer independent of the B-hole of the insert hole. The user must position the B-hole of the insert hole circumferentially such that the B-hole is opposite the radial opening. With the advantageous design of the invention, this is no longer necessary because the area of ​​the jacket through-hole provides the maximum possible opening for the B-port. This design minimizes pressure loss while introducing the B-port, and the jacket through-hole overlaps with the B-port to the maximum extent possible. In a further design, the longitudinal extension of the jacket through-hole can be divided into equal or unequal portions by a web. In this case, the web can be used to support the jacket web. This is advantageous when the width of the jacket through-hole is maximized and the width of the jacket web is therefore minimized so that these jacket webs cannot absorb fluid forces. Therefore, the extension of the jacket through-hole along the jacket from the first end region to the second end region can also include an interruption portion of the jacket through-hole interrupted by the web.

[0041] In one embodiment, the through-hole height of the jacket through-hole 119 is at least 90% of the standard borehole range (diameter) of port B. In some designs, the through-hole height is at least 100% of the standard borehole range of port B. Advantageously, this can reduce fluid pressure loss during the transition from port B to the hydraulic cartridge valve 100, and vice versa.

[0042] exist Figure 2 The image shows a stepped receiving port 11. The receiving port 11 accommodates the diameter jump of the outer diameter 121 of the sleeve 110. Furthermore, a second diameter 116 is present... Figure 2 The outer diameter 116 is shown as the outer diameter of the sleeve 110 that can be inserted. In the present case, the outer diameter 116 is implemented as an insertion ring. The outer diameter 116 of the sleeve 110 that can be inserted extends over the region of the sleeve 110 that is received in port A.

[0043] Figure 3 A schematic top view illustrates one embodiment of the sleeve of a hydraulic cartridge valve according to the present invention. The sleeve 110 has a plurality of jacket through-holes 119 spaced apart by a jacket web 118. The total width of the jacket through-holes 119 in the jacket 117 is at least 75% of the outer circumference of the jacket, preferably 80%. The width of the jacket web 118 is constant along its extension from the outside to the inside of the jacket 117. The width of the jacket through-holes 119 gradually tapers from a first width B on the outside of the jacket 117 to a second width A on the inside of the jacket 117. This forms a preferred trapezoidal cross-section.

[0044] Finally, it should be noted that the description and embodiments of the present invention should not be construed as limiting any particular physical implementation of the invention. All features set forth and illustrated in connection with the various embodiments of the invention may be provided in various different combinations within the subject matter of the invention in order to achieve their advantageous effects simultaneously.
