ABSTRACT:
Upon initiation of a steering operation, a gerotor gear set rotates a directional control valve to an actuated condition. Initial rotation of the directional control valve actuates a switch assembly under the influence of forces transmitted from the directional control valve. The switch assembly is located in one section of a housing and the directional control valve is located in another section of the housing. The two housing sections are connected in fluid communication so that there are no seals to impede actuation of the switch assembly upon rotation of the directional control valve. The switch assembly and its housing section are rotatable together with the directional control valve to adjust the initial position of the directional control valve relative to the other housing section. In one embodiment of the invention, actuation of the switch assembly effects operation of an electric motor to increase fluid flow from a pump to a steering control assembly. In another embodiment of the invention, actuation of the switch assembly effects operation of a priority valve to reduce fluid flow to an auxiliary apparatus and increase fluid flow to a steering control assembly.
