An electro-hydraulic control unit for a vehicle brake system includes a hydraulic control unit including an HCU block defining a motor bore containing an electric motor and an eccentric chamber containing a rotating eccentric driven by the electric motor. The HCU block also defines a pump bore containing a piston pump including a piston rod having a generally cylindrical shape with a smooth exterior surface extending substantially its entire length. An end cap is press fit around an end of the piston rod and includes a flange portion extending annularly outwardly for engaging a return spring. A piston guide includes a tubular portion guiding the piston rod and a shoulder for engaging the return spring. A throat of the piston guide holds a gland seal surrounding the piston rod. An outlet valve housing includes a tubular protrusion extending into the throat of the piston guide to hold the gland seal.

A conversion kit creates a redundant hydraulic, pneumatic, or mechanical control functionality for low-torque, quarter-turn plug valves in remote production environments (i.e., rural or subsea pipelines). The conversion kit comprises at least one custom end cap fitted to the valve and comprising a socket receiving a rotator attachment. Each rotator attachment is in turn connected to a crossover which connects to a bracket remotely actuated via hydraulic, pneumatic, or mechanical control. The linear movement of the bracket and the attached crossover[s] is converted to rotational force which is transmitted through the rotator attachments to the at least one valve.

The present invention relates to a hydraulic and/or pneumatic multi-coupler connector of the type comprising at least one pair of couplers inserted into a containment body and equipped with a lever actuated mechanism comprising an actuation lever maneuverable by the user for the relief of the residual pressure of the couplers and the connection thereof to corresponding male couplers.

A waste gate assembly for a turbocharger includes a valve member formed by a valve shaft and an arm attached to an end of the shaft, the arm defining a through bore, an inner surface of the through bore defining an arm groove therein. A poppet for the valve has a pin whose outer surface defines a pin groove. A generally polygonal retaining ring of elastically deformable wire is installed partially in the arm groove and partially in the pin groove to retain the poppet on the pin, thereby attaching the poppet to the arm of the valve member. An anti-rotation feature prevents relative rotation of the poppet about the pin axis. Vertices of the retaining ring are in the arm groove, while sides of the retaining ring are in the pin groove. Once the retaining ring is pre-installed in the arm groove of the arm, the arm can be assembled to the poppet by a push-to-connect process.

A pipe stopper assembly includes a stopper fitting defining a fitting channel, the stopper fitting configured to be mounted to a pipeline; and a pipe stopper positioned in the fitting channel and comprising an expandable stopper body and a pressure assembly, the expandable stopper body configurable in an expanded configuration and a contracted configuration, the pressure assembly configurable in an open configuration and a closed configuration; wherein, in the open configuration, the expandable stopper body is biased to the expanded configuration, and in the closed configuration, the expandable stopper body is biased to the contracted configuration; and wherein, in the expanded configuration, fluid is prohibited from flowing through the fitting channel, and in the contracted configuration, fluid is permitted to flow through the fitting channel.

A low-profile and small-size valve to a shut off a flow of fluid in a pipeline includes a frame, a tube, a moving part, a lever, an elastic part, a latch, and a trigger. The tube is movable with the moving part. The lever is rotatable around an axis. The elastic part can push the lever to rotate after the trigger pushes the buckle away from the lever to unlatch the lever and allow rotation. During the rotation of the lever, the lever pulls on the moving part, and the moving part pulls on the tube together to disconnect the tube from the pipe. The valve improves the convenience and efficiency of shutting off a flow of fluid. A pipeline and an immersion cooling system is also disclosed.

A fluid coupling includes a body, a poppet valve assembly, a handle shaft assembly, and a retention member. The body has a fluid conduit, a through-hole extending through a sidewall, and one or more openings that extend between an external surface of the body and an interior of the through hole. The poppet valve assembly is disposed within the fluid conduit and is selectively movable between an open position and a closed position. The handle shaft assembly extends through the through-hole and into the fluid conduit and is interconnected with the poppet valve assembly such that the handle shaft assembly can be actuated to move the poppet valve assembly between the open position and the closed position. The retention member is insertable through the one or more openings and into the through-hole to interact with the handle shaft assembly to selectively hold the handle shaft assembly in the body.
