| 20100065658 | SELF REGULATING FLUID BEARING HIGH PRESSURE ROTARY NOZZLE WITH BALANCED THRUST FORCE - 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 liquid pressure at the shaft inlet is balanced by allowing passage of a small amount of the pressurized liquid 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 liquid 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 liquid through a tapered or frusto-conical region between the shaft and housing. This further provides a liquid 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. | 03-18-2010 |

| 20080217432 | SEALING CONNECTION ASSEMBLY FOR A HANDHELD SHOWERHEAD ASSEMBLY - A sealing connection assembly for a handheld showerhead assembly has a base, a connecting assembly, a check valve and a locking nut. The base has a channel defined through the base. The connecting assembly is mounted inside the base and has a passage communicating with the channel. The check valve is mounted inside the passage of the connecting assembly to keep water from flowing back. The locking nut is used to connect a flexible hose to a handheld showerhead. The elements of the sealing connection assembly for a showerhead assembly are simple and are mounted inside the handheld showerhead. Therefore, repairing the sealing connecting assembly for a hand showerhead assembly is easy, and the appearance of the handheld showerhead is aesthetic. | 09-11-2008 |

| 20080265058 | ROTOR NOZZLE FOR A CLEANING DEVICE - 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. | 10-30-2008 |
| 20100025492 | SELF REGULATING FLUID BEARING HIGH PRESSURE ROTARY NOZZLE WITH BALANCED THRUST FORCE - 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. | 02-04-2010 |
