Actuator valve for pressure switch for a fluidic system

Hydraulic actuator comprising:

• an actuator body including an inlet, at least one outlet, a port communicating with a precharged diaphragm tank, a port communicating with a pressure switch, and a passageway communicating with the port communicating with the pressure switch and with an interior of the actuator body;
• the actuator body including a movable member which, in a first position, closes the inlet port and provides fluidic communication with the pressure switch;
• and in a second position, opens the inlet port and seals the pressure switch port;
• and
• a spring disposed within the actuator body urging the movable member toward the first position, wherein the movable member includes a bypass providing fluidic communication between the inlet and an interior of the actuator body when the movable member is in the first position and a member of a lubricious material and a lubricious coating.

• and in a second position, opens the inlet port and seals the pressure switch port;
• a spring disposed within the actuator body urging the movable member toward the first position;
• and
• a support member which guides the movable member in a sliding motion, wherein the support member includes a transverse passageway which is in fluidic communication with an axial passageway and the axial passageway communicates with the port communicating with the pressure switch,
• wherein the movable member comprises:
• a bypass providing a fluidic communication between the inlet and an interior of the actuator body when the movable member is in the first position;
• and
• a member of a lubricious material and a lubricious coating.
