The first and second positions are typically defined by physical stops on the apparatus such as shoulders, or dogs and grooves etc, and are typically placed at set positions that define the different configurations of the device. Thus, the movement of the downhole device is governed by the detent mechanism, rather than by variable factors such as pressure changes.

  • Patent number: 7938138
    Abstract: A self-sealing valve comprises a valve housing having a fluid conduit, a valve seat, a diaphragm and a support member. The valve housing is configured to pass fluid through the fluid conduit. The diaphragm provides a self-seal of the fluid conduit. The support member is configured to retain a portion of a diaphragm. The support member and diaphragm are configured to position the flexible diaphragm against the valve seat to seal the fluid conduit in a closed position of the self-sealing valve, and to facilitate movement of the diaphragm under a bias in a first direction away from the valve seat to an open position.

  • Patent number: 7661440
    Abstract: A device for regulating the flow rate of a fluid includes a housing containing a plurality of flow conduits fluidly connecting an inlet and an outlets each of the flow conduits comprising a flow control tube and a resiliently compressive occlusion tube, wherein the flow control tubes are of substantially equal internal diameter. Each of the flow control tubes has a length associated with a different flow rate. A resilient flow-blocking element is operatively associated with each of the occlusion tubes and is movable into a flow-blocking compression against its associated occlusion tube. An actuation mechanism in the housing is operable (a) to selectively engage and move one or more of the flow-blocking elements into the flow-blocking compression against its associated occlusion tube, and (b) to selectively be disengaged from any of the flow-blocking elements.

  • Patent number: 7644728
    Abstract: A splitter for faucets includes a body in which a control unit is received. The control unit includes a collar in which a ceramic disk is received. The ceramic disk has a plurality of through holes and a number of the through holes is equal to a number of the outlets of the body. A ceramic plate is connected to the ceramic disk so as to cover some of the through holes in the ceramic disk. The ceramic disk is connected with a control shaft which has a resilient member on a radial portion thereof. An end member is mounted to radial portion and includes a plurality of gaps so that when the control shaft is rotated, the protrusion on the resilient member is removably engaged with one of the gaps so as to generate a sound.

  • Patent number: 7578313
    Abstract: A rotary pilot valve in which a force required to operate the pilot valve is reduced and especially the pilot valve can be operated with a very small operating force as in a fingertip type, and the number of parts forming the pilot valve is reduced. In a body, a tank port, a pair of pump ports, a first output port, and a second output port are formed. In a cylindrical valve, a pair of notch grooves is formed and connected with each other by a balance hole. Variable throttles are formed on a side of the tank port and a side of the pump port of the notch groove. An open area of one of the variable throttles gradually increases while an open area of the other gradually reduces by tilting of an operating lever. Pressure oil lead into the notch groove through the variable throttle is output from the first output port as an intermediate throttle pressure.

  • Patent number: 7562860
    Abstract: A hand-operated pressure regulating valve for compressed air guns includes a basic valve body with a nozzle passage, threads for connection to a compressed air gun and a nozzle body, a pressure regulating unit and an actuating ring. The regulating unit is held by the ring, with a securing ring, in a bore of the basic valve body. The nozzle passage can be bridged and closed within the bore by a nozzle passage piece. The cross section of the nozzle passage can be reduced and increased by rotation of the ring and displacement of the regulating unit and the passage piece. The regulating unit has a basic body with the passage piece, a spring pin and a compression spring and, in the installed state, the pin projects through the spring out of the basic body and the bore for radial movement transversely and, by rotation of the actuating ring, latches in succession into wells in an inner surface of the actuating ring.

  • Patent number: 7455070
    Abstract: A vacuum relief safety valve includes a housing defining an inner chamber and attached to the suction-side of the swimming pool or spa pump. An air inlet aperture is formed in the housing so as to be open to ambient air. A sealing element is disposed within the housing and biased against the air inlet aperture by a spring so as to effectively seal the inner chamber of the housing from ambient air. When a maximum allowed vacuum level within the pump is exceeded, such as when a swimming pool drain is obstructed, the sealing element moves into the inner chamber and opens the air inlet aperture causing the pump to rapidly lose its prime and enabling removal of the entrapment.
