摘要： A high pressure rotary nozzle having a rotating shaft operating within a fixed housing wherein the 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.

摘要： A fluid bearing nozzle assembly is disclosed that has a hollow cylindrical body, an inlet nut fastened to the cylindrical body, and a hollow tubular shaft member coaxially carried within the housing body and captured between the inlet nut and the body. The inlet nut has a stem portion extending into a central bore through the shaft member forming an inlet bearing area rotatably carrying the shaft member thereon. The shaft member has a spray head fastened thereto for rotation of the head with the shaft member. An inner wall of the housing body and an outer portion of the shaft have complementary shapes forming a regulating passage therebetween. The shaft has helical grooves that spiral around the shaft to one or both ends to impart rotation to the shaft and spray head.

摘要： Rotary jetting tool including a rotor with axially-opposed pressure-balanced mechanical face seals. Vented upper mechanical face seal enables the rotor to be operated with the relativity low starting torque achievable using reaction forces from offset jets energized with a pressurized fluid. When rotor is displaced axially due to set-down conditions, a pressure chamber exerts a pressure imbalance on the rotor, forcing the rotor to return to a normal operating position. Alternate structure to achieve low starting torque includes a volume disposed adjacent to a lower mechanical face seal, the volume being coupled in fluid communication with the pressurized fluid. Mechanical face seal surfaces are fabricated from ultra-hard materials, such as tungsten carbide, silicon carbide, and diamond. A gage ring designed to ensure the jets remove all of the material from the gage of the protective housing before the tool can advance can be incorporated.
