Abstract:
The present subject matter provides a spray assembly for a dishwasher appliance. The spray assembly includes a housing and an impeller disposed within a chamber of the housing such that the impeller is rotatable about an axis of rotation within the chamber of the housing. The impeller includes a plurality of conduits for directing flows of wash fluid. Each conduit of the plurality of conduits can have a different size and/or shape in order to provide suitable wash fluid coverage within the dishwasher appliance.
Abstract:
This disclosure provides a fluid whirl lighting apparatus, which comprises: a housing; a coil module, disposed on an inner wall of the housing; a rotor, disposed in the housing, provided with a plurality of blades on an inner wall thereof and a magnetic module on an outer wall corresponding to the coil module; a lighting module, disposed on the outer wall of the housing while electrically coupled to the coil module; and an alarm element, electrically connected to the coil module for issuing an alarm; wherein the outer wall of the rotor and the inner wall of the housing define an air-tight space for accommodating a liquid, and the rotor is rotated by a flowing fluid propelling the plural blades for enabling a relative movement between the coil module and the magnetic module for generating electricity; and the lighting module is used for providing illumination in response to the electricity.
Abstract:
The invention relates to a fire-extinguishing mist projector (1) for producing a jet of mist oriented along an injection jet axis (7). Said mist projector comprises an ejector (8) which is supplied with high-pressure water, generates a jet of water (10) parallel to the injection jet axis (7), and is arranged in such a way that it can rotate about the injection jet axis (7). The inventive mist projector is characterized in that the projector is surrounded by a open-ended jacket tube (11) that is concentric to the injection jet axis (7).
Abstract:
Apparatus and method for spray coating of a horizontally moving web uses a spray-down unit that sprays downwardly onto the web and a spray-up unit that sprays upwardly onto the web. Each unit has adjustable cut-offs that control the length of the spray pattern by intercepting end portions of the spray pattern. The cut-offs of each unit can be adjusted to block a spray emission opening so as to prevent the entrance of contaminants when the unit is not in operation. Fluid intercepted by the cut-offs is returned for re-use. Both units are supported on a frame, and the spray-down unit can be moved away from the spray-up unit.
Abstract:
A rotating stream nozzle is provided particularly for use as an irrigation sprinkler, wherein the nozzle provides a plurality of outwardly directed and discrete water streams which are rotated in steps through a prescribed arcuate spray path. The rotating stream nozzle is adapted for mounting onto a water supply conduit and includes a swirl plate through which water under pressure flows with a swirling action into a relatively small drive chamber. The swirling water flow forces a drive ball within the drive chamber to move into repetitious impact engagement with raised anvils formed on the inner diameter surface of a cylindrical rotor lining the drive chamber and mounted for rotation within a nozzle cap. The rotor is displaced through a small rotational step each time the drive ball strikes one of the anvils, and the water is discharged from the nozzle as discrete rotating streams passing through small discharge ports in the rotor. An open window in the nozzle cap permits outward projection of some of the water streams within the prescribed arcuate path.
Abstract:
A reaction drive sprinkler, particularly of the large gun type, is provided with an improved drive assembly adapted for full- or part-circle rotation of the sprinkler in steps about the axis of a water supply standpipe. The sprinkler includes a relatively large and outwardly inclined range tube from which a relatively high energy water stream is projected a substantial distance for irrigation purposes. The drive assembly comprises a drive nozzle mounted on the range tube for bleed passage of a relatively low energy portion of the irrigation water supplied to the range tube and for directing this low energy stream into engagement with one of a pair of oppositely angled deflector spoons at the end of a counterbalanced and pivotally mounted reaction drive arm. The drive nozzle is movable with respect to the range tube and is mechanically shifted by a reversing mechanism for aligning the low energy stream first for cyclic interruption by one of the deflector spoons to rotate the sprinkler stepwise in one direction through a preselected arcuate path and then for cyclic interruption by the other deflector spoon to rotate the sprinkler stepwise in an opposite rotational direction back through the preselected path. In one preferred form, the range tube is supported for rotation by a bearing assembly which includes a force-biased seal member responsive to increasing water pressure for increasing frictional resistance to rotation whereby the stepwise movement of the sprinkler is maintained substantially uniform throughout a range of water pressures. Moreover, the range tube is advantageously provided with a discharge nozzle assembly which is adjustable to select the angle of inclination of the projected high energy water stream.
Abstract:
A stream director is disclosed adapted for mounting on a rotary sprinkler head to redirect the water stream during a segment of the rotation of the sprinkler from its intended portion of the irrigation area to another portion. A plurality of closed adjacent smoothly curved channels are employed to confine and redirect the stream emanating from the nozzle prior to its break-up whereby the spray pattern from the sprinkler is substantially as if the sprinkler were rotating through only a portion of a circular area.
Abstract:
A spray dispenser for dispensing liquid in spray form, having a housing, a rotatable spraying disk mounted to the housing, a liquid feeder for supplying liquid from a receptacle to the underside of the disk, and a fixed member spaced below the underside of the disk. The fixed member cooperates with the disk to define a metering opening which regulates the volume of liquid fed to the disk and which can be set in a zero position. A fixed threaded collar is in threaded engagement with a control cap having a tapered inner flange. A matching tapered member positioned within the flange is movable axially to urge the inner flange outwardly into fixed engagement with a bearing sleeve; and if this is done when the metering opening is in the zero position, it will remain so adjusted and no other zero adjustment need be made to the system to indicia control or preset the dispensing rate of fluid from the dispenser inasmuch as the sleeve is connected to the disk so that rotation of the cap varies the size of the metering opening. A deflector is provided to direct excess liquid back into the receptacle and thereby avoid liquid dripping outside the dispenser. The liquid feeder, fixed member and deflector are integral and detachable from the spray dispenser to facilitate cleaning. Also, a movable gate is suspended between the deflector and housing to vary the arc of the spray of liquid being dispensed.
