摘要： Provided is a check valve device having a structure with which pressurized fluid is less likely to leak from a flowpath blocked by a valve. A flowpath 2 is formed in a block 1, and a main valve 3 and a sub-valve 4 are provided in series along the flowpath 2. A primary-side chamber 5, an intermediate chamber 7, and a secondary-side chamber 6, which form a section of the flowpath 2, are formed in that order from the one end of the flowpath 2 to the other end thereof. The main valve 3 and the sub-valve 4 are opened by a pilot valve 60.

摘要： An inflation valve (20) for a sealing cuff (10) on a tracheal tube (1) has a helical ceramic spring (40) that urges a valve seal (45, 87) against a valve seat (28, 128). The actuator (51) by which the seal (45, 87) is lifted from the seat to open the valve includes a spring latch mechanism (53). The latch mechanism has three spring fingers (56) that are held resiliently in compression in a recess (60) before the first actuation of the valve. When first used, the actuator is moved forwardly to open the valve so that the free ends of the spring fingers clear the end of the recess and deflect outwardly. When the actuator (51) is released to allow the valve to close, the spring fingers (56) engage a latch surface (63) so that the spring (40) is held in greater tension.

摘要： A damping valve device (1) for a vibration damper is proposed, comprising a damping piston (2) with a check valve, which damping piston (2) divides a cylinder (31) of the vibration damper into a first working chamber (32) and a second working chamber (33), and a control arrangement (3) with a control pot (8) and a control piston (9) which can be moved axially therein. The invention is distinguished by the fact that the damping valve arrangement has a connecting channel (41) which connects the first working chamber (32) to the second working chamber (33), wherein the connecting channel (41) is arranged in such a way that it is closed at least partially by the control piston (9) in the case of an axial displacement of the control piston (9) in the direction of the damping piston (2) and is opened again in the case of an axial displacement of the control piston (9) in the direction of the pot bottom (30).

摘要： To provide a speed controller capable of controlling an action speed of an external cylinder in one stroke in a step-wise manner. The speed controller (1) includes a first flow path (16) and a second flow path (18) that allow a first port (12) and a second port (14) to be in communication with each other. The first flow path (16) is provided with a first check valve (28) for allowing flow from the first port (12) to the second port (14). The second flow path (18) is provided with a first needle valve (32), and an opening hole (28d) of the first check valve (28) is constituted as a part of a flow path. The first needle valve (32) adjusts the flow rate by changing an opening area of the opening hole (28d) with a tip portion (34a) fixed on a piston (30) in the cylinder chamber (20). The speed controller (1) further includes a third flow path (22) allowing the first port (12) and the cylinder chamber (20) to be in communication with each other. The third flow path (22) is provided with a second check valve (46) for allowing flow from the first port (12) to the cylinder chamber (20).

摘要： A valve assembly includes a valve body with a central passage, an upstream end for receiving a fluid, and a downstream end for discharging the fluid. A segment ball valve rotates between a valve open position to allow the fluid to flow through the central passage, and a valve closed position to prevent the fluid from flowing through the central passage. A check valve located within the central passage downstream from the segment ball valve is biased to prevent the fluid from traveling upstream through the central passage, and to allow the fluid to travel downstream past the check valve. A locking mechanism secures the check valve in a locked position to prevent the fluid from flowing past the check valve. A sealable cavity is located between the segment ball valve and the check valve, to contain a neutral media to achieve a double block and bleed feature.

摘要： A piston regulator of a type that seals on the low-pressure side of a valve seat (10) includes a mechanism by which the valve can be shut off, for example for transport or storage, without risk of overloading the seat (10). Two exemplary mechanisms are disclosed. The first involves applying a closing load to a regulating piston (6) via a closing piston (17) with a surface that is acted on by secondary pressure to press it away from the regulating piston (6). The second arrangement is based on a nested regulating element: an inner sealing element (901) and outer slidable casing (900) are separable when a closing force is applied. This allows the casing (900) to transfer forces arising from secondary pressure and excessive closing force; the sealing element (901) is pressed onto the seat through a load supplied by a closing spring (903). In both cases, the load on the seat is limited. The nested regulating element can additionally be loaded by an adjustment spring or similar to provide a variable-pressure regulated output.
摘要翻译：密封在阀座（10）的低压侧的类型的活塞调节器包括一个机构，通过该机构可以关闭阀门，例如用于运输或储存，而不会使座椅（10）过载的风险。公开了两个示例性机制。第一个涉及通过关闭活塞（17）将调节活塞（6）的关闭负载施加到具有二次压力作用的表面，以使其远离调节活塞（6）。第二布置基于嵌套的调节元件：当施加闭合力时，内部密封元件（901）和外部可滑动壳体（900）可分离。这允许壳体（900）传递由二次压力和过大的关闭力产生的力; 密封元件（901）通过由关闭弹簧（903）提供的负载压在座椅上。在这两种情况下，座椅上的负载都受到限制。嵌套的调节元件可以另外由调节弹簧或类似物加载，以提供可变压力调节的输出。
