    摘要： An improved flow control irrigation device automatically stops the flow of water to an area when that area has received a predetermined quantity of water and then redirects the water to another area. The device includes a chamber, a carriage assembly, and a two-step valve which is actuated by the carriage assembly. The two-step valve first reduces the static pressure within the chamber and then fully opens an outlet to direct the flow of water to another area. The device also includes internal fluid dampers to protect the device from damage as the carriage assembly and two-step valve are moved from an irrigating position to a bypass position. The irrigation device also includes a pressure release element which facilitates resetting the device to once again deliver water to an area adjacent to the device.

    摘要： A flow controlled irrigation system which automatically stops the flow of water to an area when that area has received a predetermined quantity of water and then redirects the water to another area is disclosed. The system includes an upwardly extending gate member which defines a pair of passages therein. A first of the passages directs water to an area to be irrigated while the second causes the water flow to bypass the area. A flow control member activates the gate member when a predetermined volume of water has flowed through a meter.

    摘要： A water distribution apparatus employs a self-positioning water flow actuated rotor for serially channeling water flow into each of a plurality of outlet conduits from a common source of water under pressure. The rotor, housed within an encapsulating cavity, includes a hollow hub closed at an end and having the other end in fluid communication with the source of water under pressure. A plurality of jets eject water from within the hub intermediate a pair of hub mounted discs and provide motive power for rotating the rotor. Opposed apertures in the discs provide fluid communication between the jets and serially with a selected pair of opposed outlets connected with one of the outlet conduits; the rotational positioning of the rotor corresponding with a pair of outlets is regulated by a timed solenoid. Axial centering of the rotor within the cavity intermediate the opposed pairs of outlets is provided by the water pressure acting on the closed end of the hub in conjunction with bearing members defining the limits of the hub's axial movement.

    摘要： A valve for water sprinklers and the like, with an inlet and first and second outlets, has a hinged clapper biased to close the second outlet but held closing the first outlet by a dosing device after delivery of a given volume of liquid through the first outlet. The dosing device includes a chamber communicating with the inlet via a flow regulator. Filling of the chamber with liquid moves a piston extended by a rod cooperating with the clapper.

    摘要： A fluid oscillator has a movable cylinder dividing a cavity into two chambers. Passages in the cylinder connect the inlet with each of the chambers. Outlets in each of the chambers are located so that motion of the cylinder alternately increases the size of one of the outlet openings while decreasing the size of the other outlet opening.
