PRESSURE-TRIGGERED VALVE FOR LIQUID ADHESIVE DOSING WITH CONTROLLED OPENING AND FLOW LIMITATION MECHANISM. TIP ATTACHMENT

Abstract

The invention relates to a liquid adhesive dispensing nozzle apparatus attachable to an adhesive container for the controlled application of liquid and semi-fluid adhesives. The apparatus comprises a movable valve element, valve seat surface, valve contact surface, and a pre-tensioned force element that mechanically displaces the movable valve element between open and closed positions depending on the pressure transmitted from the adhesive container. The displacement of the movable valve element in the opening direction is limited by the mechanical relationship between the valve opening movement limiting element and the valve opening limiting contact surface, creating a controlled flow passage between the valve contact surface and the valve seat surface. The adhesive passing through the controlled flow passage is transferred via the circumferential flow collection zone on the inlet side to the flow limiting element and the restricted flow passage channel.As the pressure decreases, the movable valve element, under the influence of the pre-stressed force element, moves towards the valve seating surface and returns to the closed position. The valve opening limiting structure and the post-valve flow limiting structure are arranged sequentially in the same flow path.

1 TARIFF PRESSURE-TRIGGERED VALVE, CONTROLLED OPENING AND FLOW. LIQUID ADHESIVE DOSING WITH RESTRICTION MECHANISM TIP ATTACHMENT Technological Field: 5 The invention relates to the controlled application of liquid and semi-fluid adhesives. with mechanical dosing, valve control, flow restriction and application nozzle assemblies The invention is particularly related to a detachable section of an adhesive container's outlet. bondable, mechanically controlling the adhesive flow path when no application pressure is present. The valve element, which is kept closed and moves depending on the pressure created in the adhesive container, is 10 the valve element that allows the valve to switch from the closed to the open position in a controlled manner. The adhesive flow released as a result of the opening reaches the application tip before It relates to a mechanical liquid adhesive dispensing nozzle apparatus that limits functionality. The technological scope of the invention includes liquid adhesive application equipment and mechanical dosing systems. their mechanisms, pressure-triggered valve mechanisms, pre-stressed mechanical return 15 their structures, guiding the movable valve elements and their opening movements mechanical devices for restricting flow, creating flow passage cross-sections and flow containment structures, fluid guidance channels, sealing devices, detachable connection structures and application nozzles that provide controlled liquid release. It includes. 20 Within the scope of this invention, the pressure created in the adhesive container acts as a barrier within a defined apparatus. The flow and pressure are transferred to the movable valve element via the flow and pressure pathway; when the pressure reaches a sufficient level, against the mechanical return force of the valve element The valve element is displaced towards the open position. Controlled flow in the valve area by mechanically restricting its movement 25 A transition gap is created, and the adhesive passing through this gap continues into the flow. It is directed towards a limiting mechanism. In this respect, the invention concerns the valve under pressure. mechanical valve structure that enables opening and subsequent flow of adhesive after the valve the flow control structure that restricts flow sequentially and functionally along the same flow path It falls within the scope of liquid adhesive application tip technologies with which it is associated. 30 The invention also includes a movable valve that operates when the application pressure is reduced or eliminated. the element returns to its seated position due to the effect of mechanical return force and relates to mechanical closure devices that enable the flow path to be closed again. 2 This working principle prevents the adhesive from unintentionally flowing out in the direction of the discharge when not in use. adhesive after valve during application by limiting its progress Controlling the flow through a defined cross-section using the same apparatus structure. It is carried out within. The invention encompasses handicrafts, model making, model production, and decorative applications, as well as wood. processing, packaging, parts assembly, mounting, maintenance and repair, and a certain amount of liquid or a point, line or limited application area of ​​semi-fluid adhesive mechanical systems that can be used in production and application processes requiring transfer. It falls within the scope of dosing and flow control technologies. The invention generally refers to a leak-proof and detachable 10-inch adhesive container and apparatus. The connection is established, the adhesive pressure is transmitted to the valve mechanism, and the movement the valve element opens in a controlled manner depending on the application pressure, valve keeping the movement within a defined working range, resulting from the opening redirecting the adhesive flow to a restricted flow path and application pressure When the valve element is removed, its functions include returning it to the closed position. 15 Liquid dosing and flow control are performed within an integrated mechanical structure. It operates in the field of application end technologies. State of the Art: Liquid and semi-fluid adhesives are suitable for different surfaces, bonding areas, or limited spaces. Various adhesive containers and nozzle structures for transferring to application areas, 20 Application tips and mechanical dosing devices are used. Known In applications, the adhesive is usually applied to a flexible container by the user. squeezing, tilting of the container, effect of gravity, or pressure created within the container It is directed to the exit section via an opening, channel or The material is transferred to the application surface via a narrowed application tip. These structures have 25 In a significant portion of the process, the amount of adhesive that comes out depends on the force the user applies. and varies directly depending on the geometric characteristics of the outlet channel. In these direct-flow structures, the amount of adhesive that comes out is coarse; the magnitude and duration of the applied force, the elastic properties of the container, the container the amount of adhesive it contains, the viscosity of the adhesive, the cross-section of the outlet channel and 30 This can be affected by various variables such as length and the intended use of the container. Therefore, even when similar squeezing movements are performed by the user Different amounts of adhesive can come out of the application nozzle, and especially 3 Desired dosage stability in point, line or narrow surface applications. It may not be possible to provide this. In low-viscosity adhesives, the increase in pressure that occurs when the container is squeezed, This causes a large amount of adhesive to advance through the exit channel in a short period of time. This is possible. However, with higher viscosity adhesives, it takes even longer to initiate flow. High clamping force may be required and after overcoming flow resistance The adhesive may suddenly move outwards. Therefore... The amount of adhesive that comes out depends solely on the squeezing force applied by the user and the constant Being tied to an output cross-section, it is predictable and repeatable under different operating conditions. This can make it difficult to obtain a sufficient application amount. 10 One of the major technical problems encountered in known application endpoints is the user Even when the roughly applied squeezing force is removed, the adhesive flow continues simultaneously. It is the failure to end. The residual pressure remaining inside the container causes the initial elastic structure of the container to break down. the return behavior to its position, the flow properties of the adhesive and the location in the outlet channel now leakage at the outlet end after application is complete due to adhesive or 15 Drip may occur. This situation causes unintentional adhesive to get on the work surface. transfer, formation of adhesive residue between closely spaced application points, This can lead to surface contamination and adhesive loss. Flow is only obstructed by using a cover or an external closure element. In buildings, the user must open the closing element before application and application 20 It may then need to be shut down again. The shutdown process... If not performed within the short time intervals between applications, in the exit zone The adhesive present may come into contact with the external environment, dry out, or settle in the discharge channel. This can cause partial blockage. Therefore, external storage devices used for storage purposes... a clamping element, tightening due to uncontrolled flow occurring during application 25 alone can solve leakage or dripping problems following the removal of the force. It does not eliminate it. In some known fluid transfer and application systems, movable valve elements are elastic. shut-off elements, ball valve structures, or shut-offs operated under spring force. Mechanisms are used. In such structures, the movable valve element has a seating position of 30 by forcing the flow path towards the surface and creating sufficient pressure When this happens, the flow is interrupted by separating the movable valve element from its seating surface. It is possible to initiate it. However, a valve mechanism that opens under pressure... 4 the amount of adhesive that advances to the application tip after the valve is opened It alone does not ensure controlled restriction. During the transition of the movable valve element from the closed to the open position The amount of displacement that occurs is the displacement that takes place between the valve element and the seating surface. The incoming flow can directly affect the cross-sectional area. The opening of the valve element is 5. Increased application pressure in structures where movement is not mechanically restricted, higher displacement of the movable valve element and flow passage cross-section This can lead to uncontrolled growth. In such a case, the valve, application Although it can interrupt the flow when not being done, it occurs during the application. It may not be able to ensure consistent control of the amount of adhesive. 10 The opening of the valve element releases a wide cross-section of flow in a short period of time. In this case, the adhesive is released after the pressure level required to open the valve is exceeded. A sudden increase in flow may occur, especially with manually applied adhesive. in the containers the force applied by the user is kept at a constant magnitude Since this is not possible, the valve can only be opened at a specific pressure, the application amount is 15. This may not be sufficient for control purposes. Therefore, opening the valve... In addition to its behavior, the flow passage that occurs after the valve is opened is also structurally controlled. It needs to be done. In contrast, only the cross-section of the outlet channel, nozzle, or application tip In structures based on downsizing, a different technical deficiency emerges. 20 A narrowed flow cross-section can reduce the amount of adhesive that comes out per unit time. Together, they mechanically block the adhesive flow path when the squeezing of the container ends. It does not seal properly. Pressure remaining inside the container or residual adhesive in the outlet channel. It can continue to advance through the narrowed section and there is no leakage or after application. Drip may occur. Therefore, simply restricting the flow, use 25 It does not meet the need to close the flow path on the outside. A pressure-operated valve mechanism with a flow restriction located after the valve. In systems where the structure is located within the same apparatus, the structures in question Their relative positions and flow relationships influence behavior. This is possible. The difference between the opening distance of the valve element and the resulting 30°C difference when the valve opens. where the incoming flow passage is not restricted and the adhesive exiting from this passage via a defined route to the subsequent flow restriction zone In systems where pressure is not directed, changes in application pressure affect the outlet flow. Limiting its reflection can become difficult. In this context, the opening distance of the movable valve element and the valve element and seating surface structural relationship between the flow transition gaps occurring between them It is of technical importance. The opening movement of the valve element must follow a defined operating pattern. keeping it within the specified range, the uncontrolled passage that occurs when the valve opens It can limit the growth of the adhesive passing through the said transition gap. transferring the flow through a defined flow path to the subsequent flow restriction structure valve movement and post-valve flow control are integrated within a mechanical structure. It enables the association of these elements. 10 If the adhesive passing through the valve area is released directly into the outlet channel, the instantaneous flow change caused by the opening of the valve directly to the application end Reflection is possible. Therefore, a certain amount of adhesive is needed after the valve. collection in the area, regulation of flow direction, and then a restricted passage. Passing through the cross-section, the valve opening movement and the outlet behavior at the application end 15 technical importance in terms of establishing a more controlled flow link between them It carries. Another point to consider in known designs is the movable valve element. The valve maintains its positional stability during opening and closing movements. Deviation of the element from the direction of movement, oblique contact with the valve seating surface 20 or uncontrolled contact with the side surfaces inside the valve housing, the valve this can prevent it from closing completely or cause it to jam during the opening movement. This is possible. Therefore, it protects the operating direction of the movable valve element. The presence of guiding and centering structures ensures repeatable valve movement. It is important in terms of ensuring this. 25 Similarly, the return force that forces the valve element into the closed position is structural. It needs to be checked accordingly. If the return force is insufficient... The valve element must be pressed against the seating surface with sufficient force after the application pressure is removed. It may not be able to return and leakage may occur. The return force If the level is excessively high, the user must add 30 to the adhesive container to open the valve. It may be necessary to apply excessive tightening force. Therefore, the force acting on the valve element... pressure force, return force, valve opening distance, and the resulting flow cross-section. A harmonious mechanical working relationship needs to be established between them. 6 As much as the valve element is reliably held in the closed position, the valve element itself... Establishing a proper contact relationship between the seating surface and the body is also important. Low valve capacity if the valve element makes irregular or insufficient contact with the seating surface. Even at certain pressures, adhesive penetration can occur. However, a suitable solution is needed. The creation of a contact surface, mechanical flow path in the absence of application pressure 5 to prevent closure and the unintentional spread of adhesive to areas after the valve It contributes to its limitation. Drying, thickening, or residue of the adhesive in very narrow application channels The accumulation of material within the channel can increase flow resistance and lead to partial or complete blockage may occur. When not in use, the adhesive should be kept continuously for 10 minutes. the amount of adhesive in contact with the external environment so that it can move to the exit section. This can increase and strengthen the aforementioned tendency towards blockage. Therefore the relationship between the progress of the adhesive to the exit section and the application pressure, and Flow interruption in the valve area when not in use, reusable application tips. It can provide a technical advantage in this respect. 15 Another technical problem encountered in known structures is the adhesive of the application apparatus. It is the connection with the container. The application tip is formed as a single piece with the adhesive container. In construction, it is possible to use the dosing structure on different adhesive containers. This may not be the case. In the case of attachable endpoints, the connection is only possible. It is not enough to provide mechanical adhesion; 20 when squeezing the adhesive container. no loss of adhesive or pressure should occur at the bonding area. is required. Any leakage that occurs at the connection point can lead to both adhesive loss and damage inside the container. this causes the generated pressure not to be adequately transmitted to the valve mechanism. It is possible. Geometric and dimensional differences in the outlet sections of different adhesive containers. The differences also include the use of attachable application devices. It can limit this. Therefore, in addition to the detachable mechanical connection, the connection maintaining the airtightness in the region and the pressure created inside the container is defined by the inlet. The flow must be directed through the stream to the valve operating area. Model making, miniature model making, decorative crafts, woodworking, small part assembly, 30 In packaging, maintenance and repair, and similar applications, adhesives are applied in point and linear forms. or it may need to be transferred in a controlled manner across a limited surface area. Excess Applying too much adhesive can cause it to overflow outside the bonding area, compromising surface quality. 7 This leads to deterioration, material loss, and the need for additional cleaning processes; inadequate Applying adhesive may prevent the creation of the desired bonding area. Especially in consecutive applications, the user's clamping force... limiting the direct impact of changes on adhesive output quantity. This creates a requirement. 5 When known techniques are considered together, in terms of controlling adhesive flow... It appears that there are multiple technical requirements that are related to each other. This Requirements: the flow path must be mechanically closed when no application pressure is present. holding, initiating flow when sufficient pressure is achieved, movable valve Maintaining the positional stability of the element during operation, at an application pressure of 10 the effect of changes on valve opening rate and adhesive output rate Restriction of adhesive flow after the valve, via a controlled path. the flow path is transferred to the outlet section and when the application pressure is removed This includes the need for it to be closed again. Therefore, the technical requirement is simply the use of a valve, a spring valve 15 limited to applying force to the element or simply narrowing the outlet channel. It is not. Guiding the movement of the valve element under the influence of pressure. and its restriction, resulting from valve opening, creates a controlled flow passage range. the introduction and subsequent flow restriction mechanism of the adhesive passing through this gap the transfer of functions along a defined route mechanically and 20 It needs to be related in a flow-like manner. In addition, the adhesive container of this working mechanism is removable and leakproof. The valve element is realized within a compact apparatus that can be connected in this way; It must reliably return to the closed position when the application pressure is released; The valve, guiding, motion limiting and flow limiting components are located within the apparatus. maintaining their positional stability and the adhesive's flow from the inlet to the application tip It needs to be moved along a defined flow path. Accordingly, the flow path is mechanically closed when there is no application pressure. holding, controlled displacement of the movable valve element at sufficient application pressure. allowing, by mechanically limiting the displacement in question, a defined 30 creating a flow passage gap, collecting the adhesive that passes through this passage gap. and transfers the flow to the flow restriction structure via the routing zone and the implementation 8 an integrated system that returns the valve element to its closed position when the pressure decreases. There are technical requirements regarding the mechanical dosing nozzle structure. The purpose of the invention: The main purpose of the invention is to enable the controlled application of liquid and semi-fluid adhesives to the application surface. Enables the transfer of adhesive in this manner; when there is no application pressure, the adhesive flow rate is 5. creating sufficient pressure in the adhesive container to mechanically close the channel. a valve that, when it arrives, moves the movable valve element to the open position in a controlled manner. mechanically restricting the opening movement of the element, resulting in the opening process. restricting the incoming adhesive flow along a defined flow path and If the application pressure decreases or disappears, the flow path must be reset to 10. an integrated liquid adhesive dispensing nozzle apparatus that closes mechanically. It is about developing. Another purpose of the invention is to direct the adhesive from the adhesive container into the apparatus. a mechanical device that forces the movable valve element into the closed position by generating pressure. The goal is to establish a defined working relationship between the return force and the return force.

The goal is to mechanically limit the displacement it can achieve towards its current position. By keeping the opening movement of the valve element within a defined operating range. the flow passage cross-section that occurs between the valve element and the valve seating surface uncontrolled growth and a high amount of adhesive when the valve is opened valve 10 The aim is to restrict its transfer to the post-region area. Another objective of the invention is to enable the valve to open in a controlled manner as a result of the valve element's opening movement. a defined controlled flow passage gap between the element and the valve seating surface The aim is to ensure that this occurs. In this way, the valve operates in only two ways: open or closed. Unlike being used as a closing element that creates the condition, valve 15 There is a structural difference between the opening distance of the element and the first flow cross-section through which the adhesive can pass. The aim is to establish a relationship. Another objective of the invention is to allow the adhesive to pass directly through a controlled flow passage.

Pre-stressed one side of the force element (16) is with the first force bearing surface (17), the opposite side The second force is in mechanical relationship with the bearing surface (18). The first force The positional relationship between the bearing surface (17) and the second force bearing surface (18), 15 The pre-stressed force element (16) creates on the movable valve element (13) It contributes to determining the initial closing force. To direct the movement of the movable valve element (13) inside the valve chamber (12). For this purpose, there is a valve guide element (19). Valve guide element (19), During the opening and closing movements of the movable valve element (13), uncontrolled lateral 20 restricting its movement and the movable valve element (13) to the valve seating surface (14) This contributes to maintaining proper functioning according to the valve guidance system. The element (19) has a valve guiding surface (20). Valve guiding surface (20) being in positional relationship with the outer surface of the movable valve element (13) 25 from the working axis of the movable valve element (13) or specified movement It limits excessive deviation from the correct direction. The movable valve element (13) is mechanically positioned between the closed and open positions. There is valve clearance (21) so that it can be changed. Valve clearance (21), the valve opening by separating the movable valve element (13) from the valve seating surface (14). 30 of the valve opening limiting surface (23) with the movement limiting element (22). It creates a working volume that can be adjusted to its maximum opening position. It brings about the valve movement clearance (21), the guided movable valve element (13). uncontrolled lateral or axial movement within the valve chamber (12) while allowing its movement the predicted mechanical relationship of the controlled flow transition range (24) will restrict movement and limit movement. It is structured in a way that allows it to occur within it. The mechanical movement of the movable valve element (13) towards the open position To limit the opening movement of the valve, there is a limiting element (22). opening movement limiting element (22), valve seat of movable valve element (13) 5 moving further away from the surface (14) than the determined working distance It restricts the valve opening movement in relation to the limiting element (22). There is an opening limiting counter surface (23). Valve opening limiting counter surface (23), valve opening movement limiting element (22) determined opening It is the surface that creates a mechanical response in its position. 10 Valve opening movement limiting element (22) and valve opening limiting corresponding surface (23) The distance and positional relationship between them is the maximum that the movable valve element (13) can reach. It determines the functional opening distance. Thanks to this mechanical limitation, the movable valve The opening movement of the element (13) occurs only due to the pressure that occurs in the adhesive container. not left to its size, but within a mechanically defined range of motion 15 This allows for uncontrolled flow across the valve structure in the open position. Its growth is limited in this way. As a result of the separation of the movable valve element (13) from the valve seating surface (14), the valve Controlled flow passage interval (24) between the contact surface (15) and the valve seating surface (14) This occurs. The controlled flow passage interval (24) is 20 minutes from the adhesive reservoir to the valve chamber. (12) valve-controlled flow that allows passage to the flow region after the valve It is a cross-section. The size of the controlled flow passage gap (24) is the size of the movable valve element (13) related to the opening amount of the movable valve element (13) opening amount of the valve opening by the movement limiting element (22) and the valve opening limiting counter surface (23) It is mechanically limited. 25 Environmental flow collection zone (25) following the controlled flow transition interval (24) The environmental runoff catchment area (25) is located within the controlled runoff passage interval (24). in the common flow volume of adhesive passing through different sections after the valve It ensures the collection of the environmental flow collection zone (25), directly of the adhesive.

The restricted flow passage channel (27) is located outside the environmental flow collection area. (25) the incoming adhesive through a specified cross-section, length and flow geometry By allowing passage, it creates flow resistance to the adhesive flow. Restricted Cross-sectional area, length and geometric arrangement of the flow passage channel (27), different flow Liquid or semi-fluid adhesives with different flow resistances in terms of properties 10 It can be determined in a way that will produce this result. Flow restricting element (26) and restricted flow passage channel (27) of the valve structure As a result of opening, the valve on the adhesive passes through the controlled flow passage (24). in addition to flow control in the region, sequential effects on the same flow path This creates a second flow control zone positioned in this way. 15 Opening of the movable valve element (13) allows the adhesive to pass through the controlled flow passage. (24) allows the adhesive to pass through the surrounding flow collection zone. (25) then passed through the restricted flow passage channel (27) to the outlet side of the apparatus It does not reach. Thus, the basic opening and closing function of the valve structure and what happens after the valve...

Tip exit 15 the opening (32) through which the adhesive comes out of the liquid adhesive dosing nozzle apparatus (1) It creates the final opening. The cross-section of the end exit opening (32), application It can be determined in accordance with the requirement. The end exit opening (32) is the single adhesive. The primary control element is not the dosage applied per unit, but rather the valve structure and flow restriction. The export of adhesive, which is checked beforehand by element (26) 20 It is the output element that provides the solution. The tip in the area where the application tip (31) is mechanically connected to the apparatus body (2) The connection section (33) is located. The end connection section (33) is the application end (31) It ensures that the device is held in the working position relative to the body (2).

It can be constructed in the form of a snap-fit, mechanical interlocking, or integrated body structure. In application forms where the application end (31) is made detachable, the end connection section (33), application tips (31) with different tip exit opening (32) geometries It is possible to use it interchangeably on the same apparatus body (2) 30 It can provide. The part of the apparatus body (2) where the valve and flow limiting components are located There are fuselage closing elements (34) for closing purposes. Fuse closing 23 element (34), working positions of the mechanical components inside the apparatus body (2) to contribute to the preservation and completion of the structural integrity of the apparatus body (2) It provides. In the area where the body closing element (34) is connected to the apparatus body (2). There is a closing element connection area (35). Closing element connection area (35), the body closing element (34) is fixed or removable to the apparatus body (2) 5 It has a mutually reinforcing geometry that will enable connection. The valve mechanism is in the specified operating position inside the apparatus body (2). positioning and carrying bearing of valve mechanism that ensures holding (36) It is located.

There is a valve element centering section (37) which contributes to its retention. element centering section (37), valve guide element (19) and valve guide opening and closing movement of the movable valve element (13) together with its surface (20) It supports the occurrence of a repeatable movement. Valve element 20 centering section (37) limits the lateral deviation of the movable valve element (13) in a way that will not prevent the adhesive from reaching the controlled flow transition range (24) It is structured. The working position of the flow limiting element (26) inside the apparatus body (2) There is a flow limiting element positioning bearing (38) that determines the flow. Flow 25 positioning bearing of the limiting element (38), flow limiting element (26) The inlet side of the restricted flow passage channel (27) inside the apparatus body (2) is circumferential. flow collection area (25) and outlet side with restricted flow directing surface (28) and in the working position to form a flow connection with the flow balancing zone (29) It holds. Flow restricting element positioning bearing (38), flow restricting 30 unwanted displacement of element (26) in axial, radial and / or circumferential direction These may include restraints, support or seating surfaces. 24 The liquid adhesive dispensing nozzle apparatus (1) is movable when no pressure is applied. valve element (13), closing created by pre-stressed force element (16) Under the mechanical force in this direction, the valve is held towards the seating surface (14). closing contact between valve contact surface (15) and valve seating surface (14) in position and controlled flow transition range (24) of adhesive to the area after the valve 5 It is in a position that will prevent passage. When squeezing force is applied to the adhesive container, the internal pressure of the adhesive container increases. increasing and the pressure in question is increasing in the adhesive inlet opening (9), inlet flow channel (10) and pressure The transfer is made through the transmission and valve supply area (11) to the valve reservoir (12). The pressure reaching the reservoir (12) creates a pre-tensioned force on the movable valve element (13). An opening force is generated in the opposite direction to the closing force of the element (16). It brings. The force in the opening direction of the pre-stressed force element (16) of the movable valve element (13) by exceeding the closing force on the movable valve element (13), valve seating It is moving away from the surface (14).

During the displacement of the movable valve element (13) towards the open position, the valve opens. The limiting element (22) of the movement and the limiting surface (23) of the valve opening are movable 20 It mechanically limits the opening position that the valve element (13) can reach. Therefore, the pressure in the adhesive container must be above the level required for the valve to open. The removal of the movable valve element (13) leads to unlimited displacement of the valve element. It does not open. The mechanically limited opening of the movable valve element (13) the distance between the valve contact surface (15) and the valve seating surface (14) is 25 Contribution to determining the magnitude that the controlled flow transition range (24) can reach It provides. In the adhesive circumferential flow collection zone passing through the controlled flow passage (24) (25) is collected and transferred from there to the flow limiting element (26). The restricted flow passage channel (27) in the restricting element (26), controlled flow 30 by passing the adhesive through the transition gap (24) over a defined flow cross-section This creates additional flow resistance to the initial flow control established in the valve area. The adhesive then flows through the confined flow guiding surface (28). to the balancing region (29), from the flow balancing region (29) to the outlet flow channel (30), outlet from the flow channel (30) to the application end (31) and from the application end (31) to the end outlet opening (32) reaches. When the force applied to the adhesive container is reduced or removed, the valve reservoir... (12) the pressure decreases and the opening force on the movable valve element (13) is pre-stressed 5 The force element (16) is falling below the closing force. Pre-stressed force element (16) moves the movable valve element (13) back toward the valve seating surface (14). It causes the valve contact surface (15) of the movable valve element (13) to be reseated. When it comes into contact with the surface (14), the controlled flow passage gap (24) closes and the surrounding The passage of new adhesive into the flow collection area (25) is mechanically restricted. 10 In the structural arrangement of the invention, control of the adhesive flow is only through the end exit opening (32) It is not subject to narrowing.

It forms a sequential flow control structure. Mechanical properties of the prestressed force element (16), first force bearing surface 20 (17) and the position of the second force bearing surface (18) relative to each other, movable valve the effective surface area of ​​the element (13) subjected to pressure and the valve seating surface (14) Geometry and structural parameters determine the opening characteristics of the valve structure. sizing of parameters according to different adhesive properties It is possible. However, these dimensions apply to pressure-driven 25 opening of the movable valve element (13) against the pre-stressed force element (16) and pressure the basic mechanical structure is that it returns to the closed position when the pressure decreases It does not change anything. The valve opening movement limiting element (22) to the valve opening limiting corresponding surface (23) The position of the movable valve element (13) will determine the maximum opening distance. It can be arranged in this way. By changing the positional relationship in question, the movable valve the maximum displacement of the element (13) and consequently the valve contact surface (15) controlled flow passage gap that may occur between the valve seating surface (14) 26 (24) The maximum geometric size can be determined. The restricted flow passage channel (27) The cross-sectional area, length, and geometric arrangement will also create different flow resistances. This can be determined in this way. Thus, the mechanical limitation that determines the valve opening distance. The geometric characteristics of the structure and the flow restriction structure after the valve, of the apparatus 5 while maintaining the basic mechanical working mechanism, according to different application requirements. It is resizable. Flow restricting element (26), flow restricting element positioning bearing (38) It can be positioned inside in a fixed or removable manner. Flow restriction. In application forms where the element (26) is made demountable, different cross-sections Confined flow passage channels with a specific area, length, or geometric arrangement 10 (26) different flow restriction elements (27) on the same apparatus body (2) It is possible to use it in different ways without changing the basic valve structure of the device. adhesives with specific flow properties or different flow rates for different application requirements. Boundary structures can be used. The application tip (31) is detachable via the tip connection section (33) 15 when created, it has different end exit opening (32) or different application geometry The application tips (31) can be connected to the apparatus body (2). In this case, the valve of the adhesive and while the basic mechanical arrangement for passing the flow through the flow restriction structure is preserved The transfer geometry to the target application surface can be modified. 20 through the closing element connection area (35) of the body closing element (34) If attached to the apparatus body (2) in a detachable manner, the apparatus body (2) The valve and flow restriction components inside are accessible.
