Abstract: A sprinkler head includes a base having a lower and adapted for attachment to a sprinkler system component; an elongated steam supported within the base; a nozzle and a fixed deflector supported within the stem, the nozzle and deflector cooperating to define an adjustable arcuate orifice. A water distribution plate is supported on a shaft extending upwardly from the stem and has a plurality of water distribution grooves located in axially spaced relationship to the nozzle. An arc adjustment ring is rotatably mounted on the base and is operatively connectable with the nozzle for rotating the nozzle relative to the stem for adjustment of the arcuate discharge orifice. A throttle member is secured to the upstream end of the shaft such that rotation of the shaft causes the throttle to move relative to a portion of the stem, to thereby adjust flow rate through the nozzle.

Abstract: A rotor nozzle is described whose rotor body is supported in the housing with a pre-settable axial clearance and whose end facing away from the nozzle is made in conical shape, with the conical surface forming a running surface which cooperates in operation with an axial thrust surface and braking surface fixed with respect to the housing.

Abstract: A shower head has a housing with a water inlet and a control valve which connects to the housing inlet and has a plurality of water outlets. The control valve regulates the flow of water to a plurality of circumferentially arranged spray openings and to a nozzle which is located within the periphery of the spray openings. The nozzle has the ability to turn or spin, thus providing a soft spray which may be independent of or concurrent with the discharge of water from the spray openings. The nozzle may also wobble, which movement may be described as nutational, or the slow movement of the axis of the nozzle about another axis. Wobbling movement provides a somewhat more concentrated spray than that provided when the nozzle only spins. The shower head further has an auxiliary port which may be utilized with other spray devices such as fixed sprays or hand-held shower heads.

Abstract: A sprinkler head includes a fixed nozzle; and a rotor plate spaced from the nozzle and mounted for rotation about an axis extending through the nozzle, and mounted for tilting movement about a horizontal axis. The rotor plate has adjacent water distribution grooves therein, selectively alignable with the nozzle, the grooves shaped and arranged to cause the rotor plate to rotate in opposite directions. A flow reaction member is secured to the rotor plate. A first flow channel having a first inlet port is arranged to intercept a stream emanating from one of the grooves aligned with the nozzle, and to thereby divert at least a portion of the stream through the flow channel and onto the reaction member to cause the rotor plate to tilt about the horizontal axis and align the other of the grooves with the nozzle, thereby reversing the rotation direction of the rotor plate.

Abstract: A nutating sprinkler assembly includes a sprinkler body having one end adapted to be coupled to a water supply conduit and an opposite end supporting a nozzle; at least one arm extending from the sprinkler body for supporting a removable cap assembly downstream of the nozzle, the cap assembly having a center body supporting a rotor plate having off-center grooves for distributing a stream exiting the nozzle and impinging upon the grooves. A spool bearing assembly having upper and lower bearing flanges is supported in the cap center body, and the center body mounts an interior ring loosely confining the spool bearing assembly and the rotor plate. The center body has an end wall formed with a post extending toward and received within a cavity of a lower spool bearing component of the spool bearing assembly when the rotor plate is in an at-rest position, thereby creating an unstable arrangement causing the rotor plate to tilt to an off-center position.

Abstract: A nutating sprinkler assembly includes a sprinkler body having one end connected to an adapter; a nozzle mounted in the sprinkler body captured between the adapter and the sprinkler body; at least one arm extending from the sprinkler body for supporting a removable cap assembly downstream of the nozzle, the cap assembly having a center body supporting a rotor plate having off-center grooves for distributing a stream exiting the nozzle and impinging upon the grooves; a hub having one end secured in the rotor plate and an opposite end supporting a load disc, the load disc loosely captured between opposed rings provided in the center body; the center body having an end wall formed with a tilter button extending toward and engaging a center portion on an underside of the load disc when the rotor plate is in an at rest position, thereby creating an unstable arrangement causing the rotor plate to tilt to an off-center position.

Abstract: A shower head structure includes an outer housing, a water exciting vane wheel, a water outlet cover, and a water guide barrel. The outer housing contains a ball connector, and a sealing ring pressing the ball connector. The water exciting vane wheel includes a central hollow bushing, a plurality of curved vanes, and a catch plate. The water outlet cover defines multiple straight water outlet apertures and three massaging water outlet apertures and includes an annular water dispensing barrel provided with a short stub. The water guide barrel includes a first step provided with an enlarged opening tightly pressing the sealing ring and a second step provided with a reduced section provided with a vane wheel shaft extending through the hollow bushing of the water exciting vane wheel and defining a receiving hole securing the short stub of the water dispensing barrel. The reduced section of the water guide barrel defines three oblique cut water outlet ports facing the vanes of the water exciting vane wheel.

Abstract: A nutating sprinkler assembly includes a sprinkler body having one end adapted to be coupled to a water supply conduit and an opposite end supporting a nozzle. At least one arm extends from the sprinkler body for supporting a removable cap assembly downstream of the nozzle. The cap assembly supports a gimbal bearing that, in turn, supports a rotor plate with off-center grooves for distributing a stream exiting the nozzle and impinging upon the grooves. A shaft has one end supporting the rotor plate for rotation about a center axis of the rotor plate, and an opposite end supported within the gimbal bearing.

Abstract: A Strip irrigator comprising a body member fitted with an inlet for coupling to an irrigation water supply and an outlet nozzle of said body member, defining a longitudinal axis, a distribution member formed with a water engaging portion consisting of two ducts forming between them an essentially V-like shape with an intersection adjacent a lower end thereof, each duct ending at a deflection groove, and a support bracket pivotally supporting the distribution member to the body member. The arrangement being such that responsive to a water jet emitted from the outlet nozzle, the distribution member generates reactionary forces imparting it as a reciprocal rocking motion about a horizontal axis perpendicular to the longitudinal axis.

Abstract: The present invention provides an apparatus with a moving nozzle that delivers fluid in a wobbling, rotating or oscillating pattern. The movement of the nozzle is a wobbling motion, preferably combined with some rotational motion. The wobbling motion is generated by disposing a wobble inducing member or wobble turbine in the path of the fluid supply. The water flowing over the wobble turbine causes the turbine to wobble. The wobbling turbine then causes the nozzle to wobble or rotate. The moving nozzle can be used as a motor providing a rotating output shaft or ring.

Abstract: The present invention provides an apparatus with a wobble turbine that delivers fluid in a substantially uniform spray distribution. The movement of the wobble turbine is a wobbling motion, preferably combined with some rotational motion. The wobbling motion is generated by disposing a wobble inducing member or wobble turbine in the path of the fluid supply. The water flowing over the wobble turbine causes the turbine to wobble. The wobbling turbine has outlet channels disposed therein that distribute the water. The spray pattern produced by the apparatus changes more or less rapidly so that fluid droplets or streams are directed along arcuate paths rather than at a single point. This type of spray distribution pattern is gentler than many stationary patterns and the unique design of the wobble inducing member does not include complex mechanical parts or significant flow restrictions.
