Patent number: 7578453Abstract: A handshower is disclosed providing two different radial spray patterns that can be selectively operated. There is a handle adapted for connection to a water supply, a nozzle head having an outer sleeve and an inner chamber connected to the handle, and an axially extending waterway positioned in an inner chamber of the nozzle head. On the sleeve there is an array of outlets running from the inner chamber to an outer radial face. The waterway has an axially extending channel and multiple sets of radially extending orifices. The sleeve is rotatable relative to the waterway from a first position where the channel is in communication with a first group of outlets to a second position where the channel is in communication with at least some of the outlets that are not in the first group.Type: GrantFiled: February 15, 2008Date of Patent: August 25, 2009Assignee: Kohler Co.Inventor: John M. Wilson

Publication number: 20090200401Abstract: The present invention provides a sprayer that has on the sprayer itself capability for simultaneously controlling on/off function and flow selection. A forward button can be pressed by a forefinger to turn flow on, while a rearward rocker can be controlled by a thumb to select between aerated and non-aerated flow. The on/off control is biased to the off position.Type: ApplicationFiled: February 9, 2009Publication date: August 13, 2009Inventors: John C. Esche, William R. Bares

Publication number: 20090194612Abstract: A shower head apparatus includes a shower head and an adjustable water flow rate control for adjustably control the rate of the water flow through the passage of the shower head. The adjustable water flow rate control includes a control knob and a control valve which is rotatably supported within the shower head and is driven to be rotated via the control knob, wherein the control valve has a water through channel aligning with the passage, in such a manner that when the control knob is selectively rotated at its rotational angle to drive the control valve to rotate, the water through channel of the control valve is adjustably offset with the passage for controlling the water flow rate through the shower head. Therefore, the present invention is adapted to provide better shower experience and to provide a water saver feature for the shower head.Type: ApplicationFiled: November 17, 2008Publication date: August 6, 2009Inventor: Hoi Kwan Henry Mang

Patent number: 7568639Abstract: A utility hand-piece is adapted for being worn on a hand of a user. The hand-piece includes a body portion adapted for covering at least a portion of the hand, and incorporating at least one fluid channel. A fluid inlet is formed with the body portion and communicates with the fluid channel. A fluid outlet is formed with the body portion and communicates with the fluid channel downstream of the fluid inlet. Upon connecting a fluid source to the hand-piece, fluid is transferred from the fluid inlet through the fluid channel and dispensed from the body portion through the fluid outlet.Type: GrantFiled: August 27, 2007Date of Patent: August 4, 2009Inventor: Jennifer Yip

Publication number: 20090184179Abstract: The present invention relates to a sprinkler fixing-switch, wherein the main body is installed with a pressure switch and said main body is connected with a control handle. The control handle connected to the main body presses on the pressure switch, and the main body is pivoted with a clicked-in fixing part. When said control handle connecting to the main body presses on the pressure switch, the clicked-in fixing part installed on the main body is clicked onto the control handle, rendering the control handle pressed on the pressure switch installed on the main body in order to achieve the effect of ease in control and operation.Type: ApplicationFiled: January 21, 2008Publication date: July 23, 2009Inventor: YenKun HSUEH

Patent number: 7559489Abstract: A high-pressure liquid projection assembly for cleaning and/or deburring industrial parts, having a housing with an inlet adapted for connection with a pressurized liquid source, an outlet and a fluid passageway connecting the inlet to the outlet. A fluid chamber is formed in the housing and disposed around an intermediate portion of the passageway. At least one opening is formed in the housing which fluidly connects the chamber to the passageway while a control port on the housing is fluidly connected to the chamber. The control port is adapted to be connected to a variable flow pressurized liquid source to thereby vary the projection cone pattern from the outlet as a function of the valve opening.Type: GrantFiled: August 23, 2006Date of Patent: July 14, 2009Assignee: Valiant CorporationInventor: Andrew Noestheden

Patent number: 7556211Abstract: An HVLP paint sprayer having an inlet air duct equipped with a throttle to control air volume passing through the gun. The duct has a thick wall with a slot extending down from the top just past the bottom of the internal air passage. Close to its top, the slot has on opposite sides a pair of dimples directed towards each other. This is substantially the same size as the air passage and when aligned with it does not obstruct inlet duct air flow. The throttle is positioned by the dimples engaging in recesses and by a rim flange engaging on the outside of the duct. When less air is required, the throttle is pivoted about the dimples and recesses by pressing on the flange portion not abutting on the duct. Thus, the webbed portion of the throttle is brought to one side of the aperture, effectuating a throttle.Type: GrantFiled: July 13, 2006Date of Patent: July 7, 2009Assignee: Earlex LimitedInventor: Michael Duncan

Patent number: 7549448Abstract: A linearly self-actuated hose for use in transporting fluids (liquids, gases, solid particles, and combinations of these three). Hose (30) has a biasing spring (36) that extends along its full length, and can comprise single or multiple springs and/or multiple diameter spring coils. Spring (36) is covered with hose cover material (32) on the outside and hose cover material (34) on the inside to form a sealed hose and are bowed inward or outward radially between the individual spring coils depending on the intended use of hose (30) to give the cover materials room to move out of the way when the hose retracts and the coils of spring (36) are forced close together. The Linearly Retractable Hose is operated by changing internal pressure within the hose relative to the ambient pressure on the exterior of the hose. Control of fluid pressure within hose (30) is what allows the hose to operate as an automatically extendable and retractable hose. The biasing of spring (36) depends on the type of use for the hose.Type: GrantFiled: September 26, 2005Date of Patent: June 23, 2009Inventor: Gary Dean Ragner
