Abstract: A device is disclosed that uses a flow-control methodology to control sprays at very high precision and frequency. The device is based on an enhanced Coanda effect. The control flow is selectively applied to the region in which we desire the jet to vector and control the profile (width) of the jet. In one embodiment, the control flow is applied at the desired circumferential location by the action of a rotting disk with a flow passage of a size that spreads the jet the desired amount. The size of this flow passage may be controlled by using two overlapping disks with large holes in each. By rotating one disk relative to the other, the size of the resultant passage can be modified.

Abstract: The present invention relates to an automatic water inlet switching device for an oscillating sprinkler that has a sprinkle control unit having a blade equipped gear transmission set housed therein, working together with a water inlet switching device having an operation unit and a movable swinging seat. The bottom of the movable swinging seat is provided with two water stop ends in opposite to two outlet holes defined on a coupling unit with a concaved bounded space placed at the center thereof. An action stick of the operation unit is operable inside the bounded space so that in the water inlet switching operation the swinging angle of the action stick is limited within the bounded space and the action stick will move against the push end thereof so as to produce a built-up force to instantaneously spring away the movable swinging seat no matter what the water pressure is high or low in operation.

Abstract: A sprinkler device comprising a sprinkler body having a longitudinal center axis, an inlet at one end and an outlet nozzle at an opposite end; and a rotor plate supported axially spaced and laterally offset from the outlet nozzle; the rotor plate mounted for orbital motion about the longitudinal axis and for rotation about a second axis offset from the longitudinal center axis, the rotor plate having grooves formed therein arranged to cause the distribution plate to rotate about the second axis when a stream emitted from the nozzle impinges on the plate, which, in turn, causes the rotor plate to orbit about the longitudinal center axis.

Abstract: A mechanism that steers a high energy density output(s) in a shaking motion other than a rotating motion that when translated across a surface evenly affects the surface. One application can be used as an end effector. A pivot on the mechanism induces an angular motion that eliminates the tops and bottoms of the pattern produced by the shaking motion. As a waterjet stripping mechanism which may be an end effector, a nozzle or output manifold with one or more orifices or outputs is attached to a non-rotating tube eccentrically mounted within a rotating tube that shakes the nozzle or output manifold so as to direct the stream of water to the target in a skewed circular pattern.

Abstract: A high pressure pump (14) supplies cleaning fluid from a reservoir (12) to spray nozzles (20) inside a washing chamber (10). The spray nozzles (20) spray the cleaning fluid over a load to be cleaned. Used cleaning fluid is collected in a sump (30). A sump pump (32) drains the sump. The combination of the high pressure pump and sump pump provides more efficient cleaning of the load and eliminates the requirement for a deep sump beneath the washer. A vertical traveler (22), having a pair of counterbalanced spray arms (24), raises and lowers the spray nozzles counter cyclically; a detergent injection system (50) accurately meters a correct amount of detergent is added to the cleaning fluid; and a filtration device (34) filters suspended material from the used cleaning fluid and uses a portion of the cleaning fluid to clean itself.

Abstract: A double rocking sprinkler has a first casting, a second casing coupled with the first casing, a first cover and a second cover covering the first and the second casings, and a first sprinkle plate and a second sprinkle plate disposed in the sprinkler in series. A drive device is disposed in the sprinkler for rotating the first and second sprinkle plates relative to each other.

Abstract: A spraying nozzle assembly for a dishwasher which can widely spray a washing liquid toward utensils. The spraying nozzle assembly has an adapter fixedly connected to a washing liquid outlet of a pump, a rotary spray arm which is rotatably coupled to an upper portion of the adapter and receives a washing liquid from the pump through the adapter, a spraying nozzle for spraying the washing liquid introduced into the rotary spray arm toward utensils, and a spring assembly which is coupled to the spraying nozzle and allows the spraying nozzle to be moved in such a manner that the direction of the washing liquid being sprayed therefrom is varied. The spring assembly is coupled to a fixing shaft which is eccentrically disposed with respect to a rotating axis of the rotary spraying arm. The spraying nozzle assembly can spread the spraying range of the washing liquid being sprayed, so the utensils can be effectively washed and wasting of the washing liquid can be reduced.

Abstract: A spray assembly for a dishwasher includes a fluid pump and a spray tower. The spray tower includes a lower stationary member and an upper rotatable member and includes a fluid cavity therein. The rotatable member has at least one spray opening adjacent its upper end. A spray nozzle directs a stream of washing fluid upwardly into the spray tower and moves the stream of washing fluid in a circular pattern. The stream of water engages the upper rotatable member of the spray tower and the upper rotatable member rotates in response thereto. One form of the invention uses a deflecting surface on the rotatable member for causing rotational movement of the rotatable member and for causing precession of the rotatable member. Another modification of the present invention utilizes a pair of intermeshing gears for causing precession of the rotatable member.

Abstract: A method and apparatus for a high pressure water jet automatic cleaning station for dollies or the like disclosed comprises a plurality of high pressure nozzles (152) displaced radially and also being rotatable about independent axes A. The independent axes A are arranged in radially spaced parallel relation about a central axis C. A support (158) mounts the nozzles (152) for rotation about the independent axes A and also mounts the independent axes A for revolution about the central axis C. A driver (160) revolves the independent axes A whereby the nozzles (152) provide jets of water whose impingement patterns create a uniform dense water cleaning spray. A programmer controls movement of the nozzles (152) to cause the jets to impinge on preselected areas of the dollies.

Abstract: Vehicle drying apparatus for use in either roll-over, drive-through, or tunnel type car washing installations. The dryer comprises an air plenum tube which extends overhead and transversely of the drying location and has a plurality of air outlet nozzles, the angular orientations of which relative to a vehicle being dried is subject to alteration. Means are provided for pivoting the nozzles transversely of the vehicle and, in the case of the roll-over washer, reaiming the nozzles so as to constantly direct air in a forward direction regardless of the direction of movement of the gantry frame relative to the vehicle.

Abstract: A rotatable spray manifold especially designed for a commercial dishwasher and in which the ends of the two hollow arms are closed by cleanout-caps, each cap being carried by a pair of rods that straddle the sides of each elongated arm and are pivotally secured thereto. The pair of rods form a frame that can swing the cap from closing the open end of the hollow arm into uncovering it, thus permitting access to the interior of each arm for cleaning the spray manifold. The cap is adjustably carried by the swingable frame so as to be movable into a water tight contact with the open end of the spray arm. No tools are necessary to be used in the opening or closing movement of the cleanout-cap and the cap cannot accidentally become lost.
