摘要： A quick connector includes a coupler fluidically connected by a passage to a first fluid tube. A retainer housing in axial alignment with the passage is installed on the coupler and a movable retainer is installed in the retainer housing in a first position. A second fluid tube having a raised bead formed proximate an end portion of the second fluid tube is permitted to be installed into the retainer housing cavity by the retainer when the retainer is in the first position. Moving the retainer to a second position latches the bead to the retainer housing retaining the second fluid tube to the quick connector.

摘要： A coupling bushing includes a bushing body and a retainer for locking a coupling plug into the bushing body. The bushing body has a connecting section and a coupling section, wherein the connecting section and the coupling section are fluidically connected with each other via an inner channel. A bushing valve is arranged in the inner channel (8), wherein the bushing valve (10a) comprises a valve holder, an axially movable valve body and a valve seat. The retainer has at least one latching element, wherein the at least one latching element has a resiliently elastic design. The at least one latching element is designed to engage with a coupling plug.

摘要： This disclosure relates to an irrigation system pipe joint or span coupling, which can connect a span of an irrigation system to another structure. In examples, the joint can include various components that attach an end of a first pipe or joint to an end of a second pipe or joint. For example, the end of the first joint can include a receiver plate, which can include a recess with a bushing. In addition, the end of the second joint can include a post, hook, or other elongated member that, in order to connect the first joint to the second joint, is insertable into the bushing.

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： The invention relates to a quick-change device for a filling adapter for filling vehicles on assembly lines in the automotive industry, on which circuits and containers of the vehicles are filled with operating materials which, starting from a filling system, are fed into the respective circuits and containers via hose assemblies with pneumatic and hydraulic lines and a filling adapter, wherein a separate connection plate is arranged at the separation point of the hose assembly from the filling system, and wherein a connection block is designed as a functional counterpart to the connection plate on the filling system. It is the object of the invention to create such a quick-change device which enables automatic clamping of the connection plate and connection block and which is structurally integrated into one of these two assemblies. The object is achieved in that the connection block (1) comprises a continuous channel structure (6) along its central longitudinal axis, in which structure a tie rod (3) is arranged, and in that an assembly (5) with a pneumatic cylinder (7) is arranged on the connection block (1) on the end face opposite the connection plate (2), wherein the tie rod (3) is enclosed in the channel structure (6) on a section of its axial extension by a spring assembly (4) which is supported in a fixed position on the tie rod (3) at its two end face sections by means of a respective fastening element (8), wherein the pneumatic cylinder (7) comprises a piston surface with which the upper end face of the tie rod (3) can be acted upon, wherein the tie rod (3) has, at its end section opposite the pneumatic cylinder (7), a receiving geometry (11) in the form of a cylinder screw, and wherein the connection plate (2) has a receiving geometry (9) in the form of an elongated hole in such a way that the connection plate (2) can be suspended on the tie rod (3), in that this receiving geometry (9) in relation to the longitudinal axis of the tie rod (3) passes in the radial direction from a section (A) with a first open cross section in the form of the receiving geometry (11) formed as a cylinder screw on the tie rod (3) into a section (B) with a second open cross section which has a narrower contour opening than the first open cross section and an undercut, and wherein the inner installation space from the undercut has a contour in the form of the cylinder screw (11) formed on the tie rod (3).
