<p>PROBLEM TO BE SOLVED: To provide a pump device with selector valve, capable of simply controlling the rotation drive of a rotary pump and a selector valve.SOLUTION: In a pump device with selector valve 100, a speed reduction ratio at the time when transmitting the rotation driving force of an actuator 110 to a rotary pump 120 is set to be higher than a speed reduction ratio at the time when transmitting it to a rotary valve 130. Thus, one actuator 110 is used to drive the rotation of each of the rotary pump 120 and the rotary valve 130. This allows the simple control of the pump device with selector valve 100 to compatibly improve pump efficiency and improve valve positioning accuracy.</p> |
