Document Type and Number:
WIPO Patent Application WO/2023/112738
Kind Code:
A1
Abstract:
This control valve comprises: a casing (21); and a rotor (23). The casing (21) has an inlet (37) and an outlet (34). The rotor (23) has a circumferential wall (23b) in which connection ports (39A, 39B) are formed. The circumferential wall (23b) of the rotor (23) is provided with a diameter-gradually-reduced surface (38) which is gradually reduced in outer diameter from one end side to the other end side in the axial direction and in which the connection ports (39A, 39B) are formed. A rotor storage (35) of the casing (21) is provided with a rotor guide surface which is gradually increased, in the radially-inward protruding amount, from one end side to the other end side in the axial direction and which abuts, at the radially-inward end surface thereof, against the diameter-gradually-reduced surface (38) of the circumferential wall (23b) so as to freely slide. The outlet (34) is disposed on a part of the rotor guide surface so as to face the circumferential wall (23b) of the rotor (23).
