  • Patent number: 9056325
    Abstract: Disclosed is a misting shower head having a plurality of atomizing, solid cone spray nozzles for providing a soft showering device adapted to reduce water consumption and reduce the size and intensity of outgoing water droplets. The shower head comprises a housing having a fluid inlet directing water to a plurality of spray nozzles. The flow rate entering the housing is controlled by a straight through valve that is adjustable via a dual-handled arm that actuates the valve stopper mechanism, and thus varies the rate of fluid entering the shower head housing. The nozzles break up the flow of water into atomized droplets and increase the projected area in which the water is dispersed therefrom. The atomized spray from all nozzles creates a uniform cone of low intensity water, which reduces point pressure associated with higher intensity shower heads for treating sore muscles or experiencing an encompassing mist of water.

    Abstract: A misting system has a reservoir located above the passenger compartment of a vehicle. The reservoir, which is capable of containing water and compressed gas, has a horizontally sloped bottom wall and a trough located at the bottom of the bottom wall. The trough has a trough wall that is vertically sloped so as to form a console that depends from the bottom of the reservoir. One or more misting nozzles are located in the trough wall and direct mist across the upper portions of the passenger compartment. By providing a trough, the possibility of water sloshing away from the misting nozzles and compressed gas leaking through the misting nozzles is reduced during vehicle movement. A valve is associated with each misting nozzle. The valve allows the regulation of the flow of mist from off, to partially open, to full open.

    Abstract: A variable shim and valve seat assembly for applications in a solenoid actuated fuel injector includes a variable shim having a face, a valve seat having a top surface that interfaces with the face, and mating features integrated in the face of the variable shim and the top surface of the valve seat. The mating features provide axial displacement of the valve seat through rotation of the valve seat relative to the variable shim. The mating features may be ramped surfaces. The amount of seat displacement is dependent on the designed ramp angle, the number of ramps, and the degree of rotation. Once the desired valve stroke is set, the seat is welded to the injector body to achieve a leak free interface. Tight stroke setting tolerances can be achieved by applying an axial load to the seat during stroke setting and welding.

  • Patent number: 5582742
    Abstract: For a filtering-type centrifuge, a pipe assembly composed of a stationary outer pipe with a concentric rotatable inner pipe. The outer pipe has a longitudinally extending distribution port, while the inner pipe has a helically shaped discharge port. The assembly is placed inside the centrifuge and inside of a filtering basket. As the inner pipe turns, portions of the distribution port are intersected by portions of the discharge port. This causes the slurry to exit the inner pipe at the intersection positions and be distributed in an even fashion on the basket.

  • Patent number: 4925097
    Abstract: A misting head assembly including a cylindrical rotor having a chordal flat, a center post having a flow passage, a swivel arm having a tubular portion with a radial through opening mounted for swiveling about the rotor and a connecting portion. The swivel arm connecting portion is adapted for removable mounting of a spray nozzle thereto. The rotor flat defines with the center post housing portion and swivel arm tubular portion a longitudinal flow passage for conducting water from the center post to the swivel arm opening to be sprayed outwardly therefrom through the nozzle when the swivel arm is aligned with the chordal flat of the rotor. In one embodiment, seals are provided for sealingly preventing flow of water from the longitudinal flow passage when the swivel arm is swung from alignment with the chordal flat. An indicium is provided on one end of the rotor for indicating the open position of the nozzle.

  • Patent number: 4890792
    Abstract: The nozzle assembly comprises a cap and a bushing for mounting to the front of the body of a trigger sprayer in communication with a passage in the trigger sprayer. The cap is mounted to said bushing and is rotatable on the bushing between three positions, they being a stop position, a spray position and a foam position. The nozzle has first passage means and the cap has second passage means. The respective first and second passage means are arranged to communicate with each other in the rotated spray position and in the rotated foam position of the cap. The cap is provided with foam generating means within the cap and in communication with the respective passage means when the cap is rotated to a foam position for generating foam on actuation of a trigger of the trigger sprayer to which the nozzle assembly is mounted.

  • Patent number: 4865253
    Abstract: Spraying equipment, for example for herbicides, comprises a head for carrying a rotatable disc from which, in operation, fluid is delivered by centrifugal force. The head comprises a first cmponent (4) and a second component (2) which are relatively rotatable about axis (A). The first component (4) has an inlet aperture (33) and the second component (2) has an outlet aperture (40). The second component (2) also has a recess (44) which provides a passage connecting the inlet aperture (33) to the outlet aperture (40). Relative rotation of the components (2 and 4) varies the length and/or the flow cross-section of the passage, so as to regulate the flow of fluid to the rotatable disc.

  • Patent number: 4732328
    Abstract: The inlet nozzle suitable for swimming pools is constructed as a two-piece-spherical body. This is pivotally graduated on a seating ring and equipped with a continuous bore. One part of the spherical body is, with respect to the other, rotatable about the one axis which runs eccentrically with respect to the axis of the bore. Thereby the cross-section of the bore can be changed at the transition point between both bore sections by turning of the one part of the spherical body. Between the two parts is a gap through which air from the air pipe is introduced.

    Abstract: An adjustable pattern powder spray nozzle assembly comprising a nozzle body having an axial powder flow passage extending therethrough and a pair of rotatable adjacent shafts extending across the powder flow passage. The shafts are in contact with each other substantially along their length and each has a slot formed in the periphery thereof. The slots are oppositely positioned so as to define a powder flow opening therebetween. The shafts are interconnected by gears at the ends thereof so that they are rotatable in unison to vary the configuration of the opening and thereby, the pattern of powder sprayed from the nozzle assembly.

  • Patent number: 4502640
    Abstract: A spray gun is disclosed intended alternatively for the application of plaster to walls, and the application of particulate finishing materials to the wet plaster. The gun has a hand held stock supporting a tubular housing, which receives at its front end interchangeable barrels having apertures in their side walls which can be brought into coincidence with an aperture in the housing communicating with a supply of material to be sprayed. One barrel has a handle so that it can be rotated in the housing to adjust the degree of coincidence between the openings and thus control release of particulate material into the barrel, while the other barrel is provided with a nozzle for the spraying of plaster. Compressed air for carrying out the spraying is admitted through an axial pipe connected to an external trigger.
