    Abstract: An improved sequencing fluid control valve comprising a housing having inlet and outlet ports, a valve seat disposed within the housing, a collapsible valve member disposed within the housing and forming a chamber and a bulb. A sequencing means disposed within the chamber that controls the axial motion of the valve member in response to application of fluid pressure at the inlet such that the motion of valve member alternates between an open free flowing state and a closed restricted flow state. Housing and valve member cooperate in the open position to provide an annular flow path that does not require the fluid flow direction to substantially change while flowing from inlet to outlet. Housing and valve member bulb cooperate in the closed position to form a circumferential seal to restrict the fluid flow.

  • Patent number: 4826356
    Abstract: A pressure actuated flow control valve for use in conjunction with inflatable packers and grouting systems on offshore oil platforms. The valve includes an elongated body with a plurality of pistons slidably disposed in the body between first and second positions, each piston being positioned adjacent a corresponding discharge port on the body. When in the first position, the piston sealingly closes the corresponding discharge port. When the piston is in the second position, the piston sealingly closes another discharge port adjacent the corresponding discharge port. A plurality of sleeves are annularly positioned around each of the pistons. First and second pressure lines are provided in communication with volumes adjacent opposite ends of pistons such that alternate pressurizing of the first and second pressure lines results in sequential movement of the pistons from the first to second positions.

  • Patent number: 4784325
    Abstract: A rotating stream sprinkler is provided with an improved spray head for sweeping one or more outwardly projected water streams through a prescribed arcuate spray path, wherein the spray head is adapted for enhanced self-flushing operation to prevent accumulation of grit and the like which could otherwise impair sprinkler performance. In the preferred form, the spray head is mounted at the upper end of a pop-up stem for movement to an elevated spraying position upon supply of water under pressure to the sprinkler. The water flows to the spray head and normally pressure-loads a plurality of valve balls onto a respective plurality of seats to prevent water flow through the seats to associated nozzle passages. A drive assembly rotates the spray head relative to a nonrotating cam positioned to lift one or more of the valve balls from their respective seats to permit outward discharge of one or more water streams through the nozzle passages, within the limits of the prescribed arcuate path.

  • Patent number: 4592379
    Abstract: A fluid distributing valve has the supply opening or conduit and the outlet openings or conduits disposed on the same side of the valve and oriented in the same direction. Accordingly the need for having couplings or unions to connect the supply pipe to the valve are eliminated. The valve includes a flow chamber or compartment and a control chamber or compartment so that the fluid passing through the valve does not flow past the operating members. By-passes are provided which may be finely screened to provide control water from the flow chamber to the control chamber. The valves are diaphragm operated, close, and remain closed against the flow pressure and are thus normally closed. They are open by a rotating operating cam whose operating surface moves cylindrical balls out of the way so that pressure in the control compartment can be exerted against the upper operating surface of the diaphragm operating members.

  • Patent number: 4570663
    Abstract: A distribution valve includes a housing having an upper fluid inlet, a plurality of bottom fluid outlets and enclosing a rotary impeller disposed directly beneath the fluid inlet, and a plurality of stationary baffles disposed between a bottom plate of the impeller and the fluid inlet for directing portions of the incoming fluid directly at a plurality of vertical vanes supported at the bottom plate of the impeller. A stationary planetary gear disposed about a vertical axis of the distribution valve engages a pair of symmetric gear assemblies supported on a rotary gear assembly base and each driven by a drive gear attached to the impeller. A foot-shaped cam is attached to the lower portion of the rotary gear assembly base and rotates through a 360.degree. angle, sequentially lifting each of a plurality of spherical valve balls from its seat in the bottom of the housing.

    Abstract: A control valve for irrigation and other purposes comprising an actuator mounted for rotation along a path, a motor for moving the actuator along the path, and first and second pilot valves located at first and second stations, respectively, along the path. As the actuator moves along the path, it sequentially engages the pilot valves and holds them in a first position. An adjustable selector is provided at each of the stations for controlling the length of time that the actuator holds the associated pilot valve in the first position to thereby control each of the pilot valves. The pilot valves are used to control main valves.

  • Patent number: 4290442
    Abstract: A mobile cleaning unit for providing a high pressure cleaning spray, comprising a van-type vehicle with separate sources of water and cleaning and treating solutions. Valves, one associated with each source, determine the composition of the cleaning spray by individually controlling both the introduction and the proportion of cleaning or treating solution introduced into the water as it is used in cleaning. The individual valves are successively operated in response to each initiation of flow from the source of water. The cleaning or treating solution from a particular source to be used is selected by starting and stopping flow from the source of water by operation of a flow control valve at the spray applicator.

    Abstract: The fluid valve essentially comprises a support structure designed rotatably to support an inlet within a certain oscillatory ambit and stationarily supporting a plurality of outlets within the oscillatory ambit, and operative means for effecting fluid-tight communication seriatim between the inlet and one of the outlets. The inlet is preferably a blunt needle provided with a side port and each of the outlets comprises an inverted "Y"-shaped member formed of an entrance portion and a pair of leg portions. The needle is designed to be thrust into the entrance portion, so that its side port establishes fluid-tight communication with one of the leg portions. Means are provided, including a pneumatic cylinder, for effecting relative motion between the inlet and the outlets. There is also a means for normally closing off all the entrance portions of the outlets except the selected one, and only during the entry of the blunt needle therein.
