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.
