Abstract
A power system includes: a rotating body; a housing that accommodates the rotating body; and a storage portion that is provided in a bottom of the housing to store a liquid medium. The rotating body is partially located in the storage portion, and an inner surface of the housing includes a protrusion that extends above the rotating body to intersect with a rotation direction of the rotating body.
Claims10
A power system comprising:
- a rotating body;
- a housing that accommodates the rotating body;
- and
- a storage portion that is provided in a bottom of the housing to store a liquid medium, wherein
- the rotating body is partially located in the storage portion,
- an inner surface of the housing comprises a protrusion that extends above the rotating body to intersect with a rotation direction of the rotating body, and
- the protrusion has a first guide surface that is gradually inclined or curved toward a downstream side in the rotation direction of the rotating body from an axial center portion, which serves as a vertex, of the rotating body toward both axial sides.
