    Abstract: A hydraulic valve coupling has an interlock mechanism that includes at least one blocking member within an interlock passage of a body of the valve coupling. The interlock passage has a first end opening to the valve shaft and a second end opening to an interface groove of the valve coupling. The at least one blocking member can be retracted within the interlock passage such that the valve coupling can be rotated and disengaged from a mating coupling. When the valve is in the open position, the at least one blocking member is positioned within the interlock passage such that it contacts the mating coupling and prevents rotation of the valve coupling relative to the mating coupling. The second end of the at least one blocking member can be shaped such that it is retracted as a result of contact with the mating coupling without assistance from a biasing mechanism.

  • Patent number: 8887762
    Abstract: A quick connect coupling includes female and male assemblies. The female and male assemblies include first and second valves, respectively, operable between open and closed positions. The male assembly connects to the female assembly by axial movement and relative rotation, wherein the male assembly disconnects from the female assembly by relative rotation and axial separation, wherein relative rotation of the assemblies moves the second valve between the open and closed positions. Moving the second valve from the closed to the open position allows the first valve to be movable from the closed position to the open position and moving the first valve from the closed to the open position limits relative rotation between the assemblies and prevents disconnection. Disconnection can only occur when the first valve has been moved to the closed position. Disconnection moves the second valve from the open to the closed position.

The base member holds and orients a tap and connected container to allow accessibility of a force actuator valve operator of the same. The base member includes a passageway for conducting liquid from the tap to a spout. A holder positions the base member on the first side of a partition such that the force actuated valve operator of the tap lies adjacent the first side of the partition. The spout linked to the passageway of the base member extends to the second side of the partition. An arm is operated by a handle. The arm and handle are supported by the partition such that the arm contacts the force actuated valve operator of the tap to release liquid from the container to the spout.

  • Patent number: 8551329
    Abstract: Dosing chambers, for use with pressurized water filters of the type used with ponds, require isolation before accessing to prevent water egress. The invention comprises a chamber in which dosing substances may be placed, a water inlet and a water outlet, a lid for sealingly closing the chamber, a valve for closing the water inlet and an interlock means for operating the valve to close the water inlet as the lid is removed, so that when dosing substances are placed into the chamber pressurized water is prevented from issuing through the inlet.

  • Patent number: 8550108
    Abstract: A gas pressure control valve having a valve body with a gas inlet and a gas outlet is described. An inner cap is provided bounding in part a chamber within the valve body in communication with the gas inlet. The valve body contains a spring loaded piston comprising a piston head and a piston rod. The piston rod includes a conduit providing communication between the chamber bounded in part by the inner cap and a chamber adjacent the piston head and the gas outlet. The piston is operable to move between a closed configuration in which the piston rod prevents communication between the gas inlet and the chamber bounded in part by the inner cap and an open configuration in which the piston rod permits communication between the gas inlet and the chamber bounded in part by the inner cap.

  • Patent number: 8550429
    Abstract: A coupling assembly for a compressed air circuit has locking device for releasably engaging first and second sub-assemblies located at respective ends of first and second air lines. The first air line is connected to a tool adapted for compressed air operation, and the second air line is connected to a supply of compressed air. A valve controls the flow of compressed air between the first and second air lines. The valve is connected to the second sub-assembly and is slidably movable between a first position where it allows compressed air flow, and a second position where it prevents compressed air flow. The coupling assembly has stop element for preventing disengagement of the first and second sub-assemblies when the valve is in the first position.

  • Patent number: 8434735
    Abstract: A bottom loading coupler may include a coupler body and a plurality of interlocks. Each interlock may be positioned in a corresponding slot in the body sidewall and have an engaged position and a disengaged position with respect to the coupler body. A coupler sleeve formed from a first material may be slidably positioned around the body sidewall of the coupler body. A wear ring formed from a second material may be disposed on the inner circumference of the coupler sleeve. The wear ring and the coupler sleeve may form an interlock retaining seat. The coupler sleeve may have a first, retracted position relative to the coupler body, wherein the interlocks are biased to the disengaged position and retained in the interlock retaining seat. The coupler sleeve may also have a second, extended position relative to the coupler body, wherein the wear ring biases the interlocks to the engaged position.
