摘要： A control valve includes a seat portion through which the fluid passes, a poppet which has a valve body portion and is configured to move relative to the seat portion, and a poppet throttle passage defined between the seat portion and the valve body portion. The poppet throttle passage is formed to gradually increase a flow passage area in a horizontal cross-section perpendicular to center axes of the seat portion and the valve body portion from an upstream side to a downstream side.

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： The invention relates to a valve (1) for a pressurized cooking appliance (2). Said valve (1) includes: a lower body (5) provided with a seat (6), a movable plug (7) that engages with the seat (6) in order to keep said seat at a set level, an upper body (9) that forms a channel (10) for channeling the steam (V) escaping through the seat (6), said channel (10) ending in an outlet (10A), and a decompression control member (11) designed to move the plug (7) into a decompression position. Said valve (1) is characterized in that it includes first and second conversion mechanisms designed to convert the movement of the control member (11) into a rotation of the upper body (9) and the rotation of the upper body (9) into movement of the plug (7), respectively, while keeping said outlet (10A) at a constant distance (D) from the lower body (5). The invention also relates to pressurized cooking appliances.

摘要： [Technical Problem] Provided is a check valve element enabling efficient supply of fluid while suppressing the occurrence of chattering. [Solution to Problem] The check valve element (48) is provided to be displaceable upstream and downstream in a downstream flow path (42) extending downstream from a valve seat (36) having an opening for introducing a fluid and is pressed against the valve seat by a pre-closing urging force applied thereto toward an upstream side. The check valve element has an arresting portion (48d) provided on an outer peripheral surface (48b) thereof, a sliding resistance imparting member support portion (48b-1) supporting a sliding resistance imparting member (52) such that the sliding resistance imparting member slides along the wall of the downstream flow path when the check valve element is displaced upstream and downstream, and an urging member support portion (48b-2) supporting an urging member (50b) urged upstream so that the urging member urges the sliding resistance imparting member upstream, thereby causing the sliding resistance imparting member to increase in outer diameter while being arrested by the arresting portion (48d).

摘要： A nozzle check valve comprises a valve body (10) and a nozzle (20) centrally arranged within the upstream end of valve body (10), a fluid channel (90) is defined by the outer face of the nozzle (20) and the inner face of the valve body (10). A guide bush (60) is mounted on a nozzle axial extension (26) and an annular disc (30) comprising a disc sealing ring (31) connected to a central barrel (32,33) by a plurality of webs (34) is mounted on the guide bush (60) for axial movement of the annular disc (30) relative to the valve body to open and close the fluid channel (90). A spacer (80) is arranged on the nozzle axial extension (26) downstream of the guide bush (60) and a diffuser (40) is arranged on the downstream side of the spacer (80). A spring (50) between the annular disc (30) and the diffuser (40) urges the disc towards the valve closed position. The stroke of the valve, the maximum movement of the annular disc (30) from the valve closed position to the valve open position where the annular disc (30) is in contact with the upstream face of the diffuser (40), is determined by the axial length of the spacer (80). The centre of mass of the annular disc (30) is located along the central axis of the disc (30) at an axial position where the barrel (32) is in sliding contact with the guide bush (60).

摘要： Provided is a throttle device (10) to decompress a refrigerant cooled by a condenser in a refrigerating cycle and to deliver the refrigerant to an evaporator, where a valve opening level of a needle valve (4) is controlled following a condensation pressure. Inside a cylindrical main body case (1) including a primary chamber (11) connected to the condenser and a secondary chamber (12) connected to the evaporator, a valve seat member (2) formed with a valve port (21) and a cylindrical guide member (3) integral to the valve seat member (2) are provided. A coil spring (6) to energize the needle valve (4) toward the valve port (21) side is provided inside the guide member (3). The guide member (3) guides the needle valve (4) along an axial line (L), thereby allowing an opening level of the valve port (21) to be variable. A space between the guide member (3) and the main body case (1) forms a main body side flow channel (13) to deliver the refrigerant from the valve port (21) to the secondary chamber (12). A rear space of the needle valve (4) within the guide member (3) forms an intermediate pressure chamber (44). An intermediate pressure introduction channel (45) introduces the refrigerant from the valve port (21) into the intermediate pressure chamber (44).
