Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A small diameter high pressure liquid spray nozzle assembly has a small diameter elongated cylindrical body with a tubular nozzle shaft rotatably supported within the body. A stack of several identical radial ball bearings within a sealed bearing chamber in the body rotatably supports the shaft. The ball bearings are immersed in said chamber in a viscous liquid to provide viscous damping to retard speed of rotation of the nozzle shaft. A rotary high pressure liquid sealing assembly within the body between a high pressure liquid inlet to the body and an inlet to the shaft confine the flow of high pressure liquid to a flow passage within the body isolated from the interior of the bearing chamber. The viscous damping retardation is independent of the direction of the rotary nozzle shaft.
