Thus, when the body is tightened on the conduit, a seal is made to close off the bypass passageway and the gas flow is through the first and second restricted orifices in series. When the body is loosened, the bypass passageway comes into effect and the gas flow is also through the bypass passageway to be restricted only by the second restricted orifice.Type: GrantFiled: October 12, 1989Date of Patent: June 25, 1991Assignee: Universal Enterprises, Inc.Inventor: Ralph G.

Patent number: 4951877Abstract: A device for cleaning surfaces in general by means of a liquid jet comprises a cleaning liquid entry duct (1) in which a hollow shaft (3) fitted with a drive impeller (9) is rotatably mounted. After traversing the impeller, the liquid enters the shaft to then exit in the form of a compact filiform jet through a nozzle (6) which is inclined to the longitudinal axis of rotation of the shaft. The speed of rotation of the shaft and hence of the jet can be adjusted at will from zero to a maximum value by a braking unit (23, 24). There is also provided a selector (88) arranged to assume a first position in which it enables all the liquid to enter the hollow shaft, and a second position in which part of the liquid is deviated upstream of the impeller and discharged downstream of the impeller as an atomized conical jet.Type: GrantFiled: June 14, 1989Date of Patent: August 28, 1990Assignee: Interpump - S.p.A.Inventor: Giuseppe Arsi

Patent number: 4801090Abstract: A water jet discharge pipe which produces a wide effective spray area and long water reach at low pressure and water volume. Compressed air is injected around the periphery of the pressurized water stream produced through an inner cylindrical member and which is throttled by a nozzle extending into such inner cylindrical member. The injected air prevents reduction of the flow velocity of the water by contact with the inner wall of the cylindrical member. In addition, external air is introduced through air inlets in an outer cylindrical member extending from the inner cylindrical member so as to straighten the air layer accompanying the water jet exiting from the inner cylindrical member and suppress premature dispersal of the water stream prior to ejection from the outer cylindrical member. After such ejection, expansion of the injected air atomizes the water stream to provide large area coverage thereof.Type: GrantFiled: October 7, 1986Date of Patent: January 31, 1989Assignees: Hochiki Corp., Kabushiki Kaisha Takenata KomutenInventors: Yoshiyuki Yoshida, Kazutaka Onozuka, Yoshihiko Ohashi, Toshihide Tsuji, Kensuke Miyazaki, Yoshio Koyama

Patent number: 4781537Abstract: A hydrokinetic amplifier 10 having a primary liquid input formed into a primary liquid jet surrounded by a motivating vapor that transfers vapor momentum to the primary liquid jet and accelerates the primary liquid jet through a minimum cross-sectional area 20 upstream of a diffuser is provided with a secondary inlet that admits a secondary fluid to merge with the primary liquid jet in a diffuser 16 beyond the minimum cross-sectional area. Without varying the primary inflows of liquid and vapor, the secondary flow varies inversely with the fluid flow resistance of the output load; and this can be used to vary the volume, pressure, and temperature of the output. The product of the pressure and volume of the combined flows can exceed the product of the pressure and volume of the primary flow, and change in the load resistance can be used to turn the secondary flow on and off for adding a material to the primary flow.Type: GrantFiled: February 3, 1988Date of Patent: November 1, 1988Assignee: Helios Research Corp.Inventors: Carl D.

Patent number: 4676435Abstract: A sprayer comprising a housing (10) having an internal aperture in which a spool (12) is mounted for translational movement is disclosed. The spool has a nozzle (32) mounted to it. A cavity (30), formed in the spool, is configured to provide a passageway for directing fluid from an inlet (20) in the housing to the nozzle when the sprayer is in a spraying position. The cavity also provides a fluid passageway from the fluid inlet to a fluid outlet (21), which is also formed in the housing. The latter fluid passageway permits a reverse fluid flow through the nozzle. The direction of the reverse fluid flow is opposite to spraying flow direction. Thus, the reverse fluid flow cleans the nozzle by removing matter that clogs the nozzle. A pneumatically actuated, double-acting piston and cylinder assembly is used to move the spool between the spraying position and the cleaning position.Type: GrantFiled: April 1, 1986Date of Patent: June 30, 1987Inventor: Nickolas B.

Patent number: 4664313Abstract: A water ejecting gun simultaneously produces two kinds of ejecting flows, a straight flow and a spray flow. The gun disposes a rotating or spiral fan element in a water passage for producing the spray flow. The straight flow acts as a carrier for the spray flow. A mechanism for producing the spray and straight flows includes an inner sleeve, an outer sleeve rotatably and axially movable on the inner sleeve, a nozzle element disposed in the inner sleeve which defines a main flow passage and a sub-flow passage and a frusto-conical core element engaging the upstream end of the nozzle element to form a variable gap therebetween. When the gap is open, water flows to the main flow passage. When the gap is closed, a smaller water flow to the main flow passage occurs through radial and axial passages in the core element. The straight and spray water flows exit the gun simultaneously through an ejecting opening.Type: GrantFiled: June 3, 1985Date of Patent: May 12, 1987Inventor: Rikizo Yoneda

Patent number: 4657185Abstract: An improved showerhead comprising a nozzle and a ring valve. The interior of the nozzle defines a secondary fluid passageway. The exterior of the nozzle includes a plurality of grooves on the front portion of the nozzle. The nozzle also includes at least one opening through its sidewall. The ring valve includes a recessed cavity and fits over the nozzle in sliding engagement with the nozzle between a first and second position. When the ring valve is in its first position, the recessed cavity communicates with both the opening and the channel passageways to form a primary fluid passageway, permitting water to flow through both the primary and the secondary fluid passageways. When the ring valve is in its second position, the inner surface of the ring valve blocks the opening through the nozzle sidewall such that fluid flows through only the secondary fluid passageways rather than the primary channel passageways.Type: GrantFiled: May 1, 1985Date of Patent: April 14, 1987Assignee: Associated Mills, Inc.Inventor: Alfons Rundzaitis
