  • Patent number: 7404415
    Abstract: An intermittent fluid flow controller including a main body that houses an inlet in controlled fluid communication with an outlet, a mechanical timing mechanism including a rotatable member that rotates during an operation of the timing mechanism, and a first valve operated by the rotatable member. The first valve is disposed in the main body such that a rotational movement of the rotatable member actuates the first valve to intermittently permit and restrict a fluid flow between the inlet and the outlet over a pre-selected period of time determined by the operation of the timing mechanism.

  • Patent number: 7252113
    Abstract: An in line mechanical timing valve is disclosed. The valve has an inlet capable of being coupled to a water source and an outlet. A valve housing is fluidly coupled to the inlet and the outlet to control water flow between the inlet and the outlet. A bisecting cylinder is installed perpendicular to the inlet and outlet. The bisecting cylinder has a central axis and a diaphragm which has an open position allowing water flow to the outlet and a closed position preventing water flow to the outlet. A dial knob has an extended position and a retracted position. The dial knob is rotatable about the central axis of the bisecting cylinder when in the retracted position. A timing mechanism has a windup shaft parallel to the central axis of the bisecting cylinder. One end of the windup shaft has one end coupled to the dial knob which allows the timing mechanism to be set by the dial knob. A shaft parallel to the central axis of the bisecting cylinder is inserted through the timing mechanism.

  • Patent number: 7140561
    Abstract: An adjustable spray wand is disclosed. The spray wand comprises a spray head body, a swiveling member, a locking mechanism, and a handle. The spray head body is rotatably coupled to the swiveling member. The spray head further has a locking mechanism having a contact arm having a first position allowing the swiveling member to rotate relative to the spray head body and an engagement position engaging the swiveling member and locking the swiveling member in one position.

  • Patent number: 6796515
    Abstract: A one touch valve for activating fluid flow between an inlet conduit and an outlet conduit is disclosed. The valve has a flow cylinder defining an inflow chamber in fluid communication with the inlet conduit and an outflow chamber in fluid communication with the outlet conduit. The flow cylinder includes an end plate and an intermediate plate having a center collar with an aperture. A flexible diaphragm is provided with a sealing surface in contact with the collar to create a seal. The diaphragm has an edge coupled to the intermediate plate and a small diameter hole providing fluid contact between the inflow chamber and an intermediate chamber which is defined by the intermediate plate of the flow cylinder. A plunger is placed on the diaphragm to create a seal with the opposite surface of the diaphragm from the sealing surface. A shaft has one end connected to the plunger and extends through the aperture of the diaphragm.

  • Patent number: 6604697
    Abstract: A self propelled sprinkler is disclosed. The sprinkler has a support body with a drive unit which drives two rear wheels. The drive unit is powered by water pressure supplied through a hose which is coupled to the drive unit via a hose coupler. The drive unit has a cylindrical drive chamber with circular impeller in fluid communication with the hose coupler. The impeller is rotated by the water pressure and is mechanically connected to a lateral shaft. The shaft is connected to the rear wheels. Reduction gearing from the impeller to the shaft governs the speed of the sprinkler. The reduction gearing is achieved through a series of sun gears, carrier disks and planet gears. The drive unit also has an outlet which has a socket which allows the exit of the pressurized water. The socket allows the insertion of any variety of sprinkler heads. Thus, the sprinkler allows a variety of water distribution patterns. The sprinkler is propelled by water pressure rotating the impeller and eventually the rear wheels.

  • Patent number: 6547166
    Abstract: A pattern adjustable flow nozzle which maintains a constant fluid flow rate is disclosed. The flow nozzle is comprised of two parts, an inner tubular body and an outer tubular sleeve, rotatable one on the other. Orifices are disposed on the output end of the tubular body and tubular sleeve, and the superposition of those orifices in various rotational alignments determines the throw and pattern of the ejected fluid. Flow cavities on the inner tubular body allow for a constant rate of fluid flow over the range of orifice superpositions.
