Abstract
There is provided a rotary valve that suppresses deformation of a sealing member and prevents leakage of a fluid while reducing a size of the rotary valve. The rotary valve includes: a rotor that controls circulation of the fluid by rotating about an axis; a sealing member having an opening through which the fluid flows, the sealing member being disposed on a radially outer side of the rotor; a housing that accommodates the rotor and the sealing member; and a cover placed on the housing in such a way as to face against the rotor and the sealing member in an axial direction along the axis, and the cover includes a pressing portion that presses the sealing member when the cover is placed on the housing.
Claims4
A rotary valve comprising:
- a rotor that controls circulation of a fluid by rotating about an axis;
- a sealing member having a plurality of openings through which the fluid flows, the sealing member being disposed on a radially outer side of the rotor;
- a housing that accommodates the rotor and the sealing member;
- and
- a cover placed on the housing in such a way as to face against the rotor and the sealing member in an axial direction along the axis, wherein
- the cover includes a pressing portion that presses the sealing member when the cover is placed on the housing,
- the plurality of the openings are formed in the sealing member along a circumferential direction of the rotor,
- the pressing portion includes a plurality of protrusions along the circumferential direction, and
- each of the plurality of protrusions is arranged at a position that is aligned with a position of each of the plurality of openings.
