Abstract
A rotary valve includes: a motor; a rotor shaft that is axially rotated by the motor; a housing that accommodates the rotor shaft in an internal space thereof; a stator fixed to the housing on a distal end side of the rotor shaft; a rotor that is held at the distal end of the rotor shaft and rotates together with the rotor shaft; a bearing that is interposed between an inner peripheral surface of the housing and an outer peripheral surface of the rotor shaft, supports the rotor shaft, and engages with the rotor shaft in an axial direction of the rotor shaft; and an elastic member that is provided in the internal space of the housing so as to urge the rotor shaft toward the stator side via the bearing, independently of the rotation of the rotor shaft.

A rotary valve, comprising:
- a motor;
- a rotor shaft that is axially rotated by the motor;
- a housing that accommodates the rotor shaft in an internal space thereof;
- a stator fixed to the housing on a distal end side of the rotor shaft;
- a rotor that is held at the distal end of the rotor shaft and rotates together with the rotor shaft;
- a bearing that is interposed between an inner peripheral surface of the housing and an outer peripheral surface of the rotor shaft, supports the rotor shaft, and engages with the rotor shaft in an axial direction of the rotor shaft;
- and an elastic member that is provided in the internal space of the housing so as to urge the rotor shaft toward the stator side via the bearing, independently of the rotation of the rotor shaft.
