Abstract: A housing has a housing main body and an outlet port. The housing main body includes a cylindrical housing inner wall that defines an internal space therein. The outlet port fluidly connects the internal space and an outside of the housing main body to each other. The valve has a valve body rotatable about an rotation axis along a rotation axis of the cylindrical housing inner wall. The valve is configured to selectively open and close the outlet port depending on a rotation position of the valve. The housing inner wall is formed such that a distance between the housing inner wall and the axis of the housing inner wall varies in a circumferential direction.

Abstract: A housing has a housing main body that defines an internal space therein, an inlet port that fluidly connects the internal space and an outside of the housing main body to each other, and a relief port that fluidly connects the internal space and the outside of the housing main body to each other. Coolant water flows into the housing through the inlet port. A relief valve is disposed in the relief port and configured to selectively allow and block fluid communication between the internal space and the outside of the housing main body via the relief port by selectively opening and closing the relief port in accordance with conditions. A valve has a valve body rotatable about a rotation axis in the internal space, and a shaft disposed along the rotation axis. A covering portion is configured to cover the relief valve not to be visible through the inlet port.

Abstract: A valve device includes a shaft, a housing defining a flow passage and having a plurality of openings, and a first movable disk and a second movable disk being rotatable. The plurality of openings includes one-side openings and other-side openings. The housing includes a one-side partition wall partitioning the flow passage into a plurality of one-side flow passages and an other-side partition wall partitioning the flow passage into a plurality of other-side flow passages. The first movable disk is rotated to switch a one-side flow passage communicating with a first through-hole. The second movable disk is rotated to switch an other-side flow passage communicating with a second through-hole.

Abstract: A rotary-type valve device includes a driving unit, a shaft, a valve, and a housing. The valve includes an outer circumferential portion that defines an outer circumferential opening. The housing defines a valve housing space, an inlet opening, and an outlet opening. The valve includes a passage and a valve end surface that faces the housing and that defines an end surface opening. The housing includes a housing inner surface that faces the valve end surface. The valve is housed in the housing so that a gap is defined between the valve end surface and the housing inner surface. The housing inner surface includes a protrusion protruding in the axial direction from the housing inner surface.
