Abstract:
1. A multi-way selector valve comprising a valve body rotated by a flow path switching actuator, and a valve main body rotatably holding the valve body, wherein the flow path switching actuator is a stepping motor comprising a rotor placed on the inner peripheral side of a can, and a stator placed on an outer periphery of the can; wherein a planetary gear type speed reduction mechanism is inserted between the rotor of the stepping motor and the valve body; wherein the valve body internally comprises a high-pressure path section formed for introducing high-pressure fluid; wherein the valve main body comprises a valve seat section having a first inlet/outlet and a second inlet/outlet; wherein the first inlet/outlet and the second inlet/outlet selectively communicate with the outlet side of the high-pressure path section; wherein the valve main body further comprises a valve chamber for selectively introducing low-pressure fluid through the first inlet/outlet and the second inlet/outlet; wherein, when the multi-way selector valve switches a flow path, an outlet-side end section of the high-pressure path section in the valve body slides between the first inlet/outlet and the second inlet/outlet in the valve seat section; and wherein one or more paths are formed to substantially communicate the valve chamber to which the low-pressure fluid is introduced with an inside of the can.
