Publication number: 20100025492Abstract: A high pressure rotary nozzle having a rotating shaft operating within a fixed housing wherein the of axial force which acts upon the shaft due to the fluid pressure at the shaft inlet is balanced by allowing passage of a small amount of the pressurized fluid to be bled to an area or chamber between the outside of the opposite end of the shaft and the inside of the housing where the fluid pressure can act axially in an opposing direction upon the shaft to balance the axial inlet force. The balance of axial forces is self-regulating by controlling escape of the fluid through a tapered or frusto-conical region between the shaft and housing. This further provides a fluid bearing between the two surfaces and allows use of interchangeable rotating jet heads having jet orifices which can be oriented in virtually any desirable configuration including axially forward of the nozzle.Type: ApplicationFiled: October 12, 2009Publication date: February 4, 2010Applicant: StoneAge, Inc.Inventor: Douglas E.

Patent number: 7484674Abstract: The present invention provides an improved water flow switching mechanism of a gear-type sprinkler, which addresses problems of typical gear-type sprinklers, such as invalid water switching and poor stability. The gear-type sprinkler includes a water inlet portion, a water outlet portion and accommodating space. A convex framework is additionally placed onto the accommodating space opposite the separate water outlets. Two lateral grooves are defined in the convex framework, each corresponding to a water outlet. So the pivotal portion of the rotary switching seat is assembled centrally into the convex framework. The rotary switching seat is provided with two opposite extension flanges. The extension flange may block the lateral groove of the convex framework in line with the swinging direction of the rotary switching seat. The water-stop area of rotary switching seat is greatly increased, thus ensuring the stability of the water flow switching state and improving performance of the sprinkler.Type: GrantFiled: September 18, 2007Date of Patent: February 3, 2009Inventor: Hsin-Fa Wang

Publication number: 20080265058Abstract: A rotary nozzle for a cleaning device, specifically for a high pressure cleaning device. The device has a housing with a fluid inlet and outlet for the passage of the fluid. Within the housing, there is a nozzle body traversed and rotated by the fluid. The rotary nozzle body is designed so that it will not be in direct contact with the housing's inner surface during rotation, but rather a fluid film is built up around the nozzle body. The fluid film is created because the nozzle body does not rotate around its own center axis, but only around the center axis of the housing.Type: ApplicationFiled: April 28, 2008Publication date: October 30, 2008Inventor: MARTIN F. WIMMER

Patent number: 5947387Abstract: A rotatable high pressure tool for cleaning hollow objects by forcing a high pressure fluid such as water from nozzles to create cleaning jet streams and use jet reaction at the tool to continually change the direction of the jet nozzles about a longitudinal axis of the tool while the jets are carried by a cross body rotating about an axis essentially perpendicular to the longitudinal axis. Each of the nozzles provides the same amount of reaction torque to rotate the cross body about its axis. This torque is selectively adjustable at the tool before use by similarly releasing, changing and reclamping the orientation of all nozzles relative to the cross body and by changing the discharge diameters of uniformly sized nozzle tips. The adjustable nozzles are interconnected by gearing so that the changes in orientation of all nozzles during adjustment will be the same.Type: GrantFiled: August 23, 1996Date of Patent: September 7, 1999Assignee: Stoneage Inc.Inventors: Gerald P.

Patent number: 5662744Abstract: A one-piece wash arm is provided for a dishwasher. The wash arm has an open channel through which water from a water supply hose is directed. The channel has opposite curved ends with discharge openings through which the water is sprayed onto objects to be washed in the dishwasher. The flow of water through the channel and the curved ends imparts rotation to the wash arm. In a preferred embodiment, the open channel is downwardly facing, and the water is substantially maintained in the channel due to the water pressure, velocity and surface tension. In an alternative embodiment, the open channel is directed upwardly.Type: GrantFiled: June 5, 1996Date of Patent: September 2, 1997Assignee: Maytag CorporationInventors: Barry E. Tuller, Thomas M.

Patent number: 4903364Abstract: Cleaning underlying surfaces, especially irregular surfaces, such as shake roofs, grooved pavements or ramps, and the like. Mobile apparatus under the guidance of an operator brushes the underlying surface and sprays water or other cleaning liquid onto it in a rotating pattern as the operator traverses the apparatus and, thus, the cleaning locus relative to the supporting surface. A "compass point" wheel arrangement enables the apparatus to be positioned with one wheel off the edge of the supporting surface to clean over the edge while maintaining three-point stability, whereas temporary removal of a wheel enables close approach to clean an intersection of the underlying supporting surface and an adjoining wall or other adjacent upright surface.Type: GrantFiled: July 8, 1988Date of Patent: February 27, 1990Inventor: Jerry T.

Patent number: 4640462Abstract: A handheld water driven shower massager unit is provided which includes a housing having an internally disposed rotatable nozzle which is caused to rotate by the high velocity discharge of water from the nozzle. By eccentrically weighting the water discharge nozzle, an oscillating vibrational motion is applied to the entire device, thereby providing a massaging effect when pressed against the user. When held away from the user, the unit functions as a source of water spray for cleansing. The performance and characteristics of the unit can be modified through varying the flow rate of water through the unit, by changing the nozzle configuration, or by changing the angle of water discharge from the nozzle. Additionally, various cleansing and massaging pads can be removably attached to the unit in accordance with the needs of the user.Type: GrantFiled: June 10, 1985Date of Patent: February 3, 1987Inventor: R.
