Abstract
A pump apparatus with a switching valve includes an actuator that is rotationally driven, a pump, a switching valve and a driving power interrupting device. The pump discharges a fluid sucked by rotational driving of the actuator. The switching valve is changed in phase by the rotational driving of the actuator so as to be switchable among a plurality of destinations of the fluid discharged from a pump chamber of the pump. The driving power interrupting device for a valve is switchable between a state where rotational driving power of the actuator is transmitted to the switching valve and a state where the rotational driving power of the actuator is interrupted.

A pump apparatus with a switching valve, comprising:
- an actuator that is rotationally driven;
- a pump that discharges a fluid sucked by rotational driving of the actuator;
- a switching valve that is changed in phase by the rotational driving of the actuator so as to be switchable among a plurality of destinations of the fluid discharged from a pump chamber of the pump;
- and
- a driving power interrupting device for a valve that is switchable between a state where rotational driving power of the actuator is transmitted to the switching valve and a state where the rotational driving power of the actuator is interrupted,
- wherein the pump is a rotary pump that makes the pressure of the sucked fluid high through the rotational driving of the actuator to discharge the high-pressure fluid, and
- wherein the pump apparatus with a switching valve further includes a speed change gear that makes a reduction ratio when the rotational driving power of the actuator is transmitted to the rotary pump greater than a reduction ratio when the rotational driving power of the actuator is transmitted to the switching valve.
