WIPO Patent Application WO/2013/176158

Kind Code:

A1

Abstract:

Provided is a rotary valve which uses a sealing member having a shape combining multiple functions. The rotary valve is equipped with a rotor (1), and a casing (2) having a rotor-storage space (2a) for storing the rotor (1). The rotor (1) is provided with a rotor opening (15) for serving as a channel for a coolant. Openings (25a, 26a) which are capable of connecting to the rotor opening (15) are provided at positions of the inner-circumferential surface of the rotor-storage space (2a) which face the outer-circumferential surface of the rotor (1). A sealing member (77) is positioned so as to extend from the openings (25a, 26a) to the rotor (1). A tip-contact part (80) of the sealing member (77) contacts the rotor (1) and is equipped with an inside-curved section (81). The inside-curved section (81) functions as a seal and as a spring, grows increasingly narrower on the inside in the direction toward the tip-end side thereof, and curves so as to fold back on itself.
