摘要： A locking member is mounted to the housing to be able to move in the outer diameter direction by a tapered portion of the tubular body, when the tubular body is inserted. The housing is equipped with slits formed to pass a curved portion bent in the inner diameter direction disposed at a leading-end side of the locking member and to lock with the engagement portion of the tubular body mounted on the housing. A gap is disposed between the curved portion, and the end portion of the slit positioned at a side in an opposite direction to the leading-end side of the locking member, so that there is no contact while at least the locking member is moving.

摘要： A breakaway coupling for connecting two fluid lines, comprising a first coupling part (3) which can be connected to the first fluid line and a second coupling part (4) which can be connected to the second fluid line. The coupling parts (3, 4) can be disconnected from one another by way of a defined disconnecting force, wherein at least one of the coupling parts (3, 4) has an outflow prevention valve (20) with a valve seat (21) and with a sealing body (14) which is configured for interaction with the valve seat (21). The outflow prevention valve (20) has a hold-open element (16) which is configured to enable a passage of the fluid in the joined-together state of the coupling parts (3, 4). The outflow prevention valve (20) is configured to prevent an outflow of the fluid from at least one of the fluid lines in the disconnected state of the coupling parts (3, 4). The breakaway coupling has an anti-rotation safeguard which, during operation of the coupling, prevents a rotation of the first coupling part (3) and the second coupling part (4) with respect to one another. According to the invention, the valve seat (21) has a bearing surface (24) for the sealing body (14), wherein a compensatory element (25) is arranged in the region of the bearing surface (24), which compensatory element (25) consists of a material which has a lower hardness than the material of the valve seat (21) and/or than the material of the sealing body (14).

摘要： Fluid couplings described herein are designed to prevent spillage of fluid when connecting and disconnecting the couplings. In some embodiments, the fluid couplings described herein include internal valve components. In some example embodiments, the internal valve components include two springs that are arranged to exert their spring forces in parallel with each other to bias a valve component to a normally closed position. Some embodiments include a single spring. In particular embodiments, components of the fluid couplings and fluid flow paths of the fluid couplings have oblong transverse cross-sectional shapes.

摘要： A connection to releasably connect and disconnect to a pipe to a fitting provides a pipe fitting body for receiving a pipe and a retaining ring located within the fitting body for retaining and releasing the pipe. The retaining ring has axially extending resilient retaining tabs, each of which has a radially inwardly extending portion for engaging the pipe, and, a radially outwardly extending portion which extends through corresponding radial openings in the fitting body. When the pipe is inserted into the fitting body to an inserted position and the retaining ring is in the first locked axial position, the radially inwardly extending portions engage and retain the pipe in the inserted position. Relative axial movement of the retaining ring with respect to the fitting body from the first locked axial position to a second unlocked axial position causes the radially outwardly extending portions to operatively engage the corresponding body radial openings to resiliently radially outwardly deform each resilient retaining tab thereby disengaging the radially inwardly extending portions from the pipe and permitting removal of the pipe from the inserted position.

摘要： This female element of a quick connector that connects to a male element and has a hollow body, which extends along an insertion axis and which delimits a receiving volume for the male element. Radial openings, formed in the body along a radial axis, open into the receiving volume. Each radial opening receives a latch, translatable in relation to the body along the corresponding radial axis, between a locked and an unlocked position. The female element has an actuating ring arranged about the body and translatable between a locked and an unlocked position. The ring has guide grooves, which interact with pins of each latch. The guide grooves associated with each latch are geometrically carried by a guide plane inclined in relation to the insertion axis so that each latch is driven between its locked and unlocked positions when the actuating ring is moved between its locked and unlocked positions.

摘要： A fluid interaction device for establishing an interaction with a fluid, particularly a brake fluid or a fuel fluid. A housing member accommodates a fluid interaction portion. The fluid interaction portion is adapted to interact with a fluid within the housing member. The housing member further comprises a connection portion which can be connected to a fluid supply element. The connection portion is formed as a weldable, tubular end portion so that the housing member can be connected to a joining portion of the fluid supply element by means of a welded joint.

摘要： Fluid couplings described herein can prevent spillage of fluid when disconnecting the couplings after use. In some embodiments, the fluid couplings described herein include internal valve components but no springs, or no springs in the fluid flow path. In some embodiments, the internal valve components of a male coupling and a female coupling can be designed to latch together in an abutted arrangement. By latching the valve components together, the tendency for fluid to spill when disconnecting the fluid couplings after use can be mitigated, and the necessity to use springs to operate the valve components can be reduced or eliminated.

摘要： A fluid female coupling element (11), comprising a female body (21), able to receive a male coupling element (2), a bolt (41), mounted sliding transversely between a holding position and a releasing position of the male coupling element and a plunger (51), movable between forward and rear positions. To automatically oppose the removal of the male element fitted within it, even if the male element has a reduced length, the female coupling element (11) comprises a memory ring (61), movable between an advanced position for holding the bolt (41) in the releasing position and a withdrawn position allowing the movement of the bolt (41) toward its holding position, the plunger (51) driving the memory ring (61) toward the withdrawn position when the plunger moves toward the rear position and the memory ring being in the advanced position in the uncoupled position.
