ABSTRACT:
Axially spaced distributor grooves externally formed on a rotatable controller valve element conduct pressurized fluid to a servomotor in response to axial displacement of the valve element within a housing enclosing pressurized spaces to which opposite axial ends of the valve element are exposed. Flow of the pressurized fluid through the grooves is controlled by slide valve surfaces on the valve element axially between the pressurized spaces and the grooves.
