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.
Claims12
A valve device comprising:
- a shaft extending along an axial direction, the shaft being configured to rotate about a predetermined axis;
- a housing defining a flow passage through which a fluid flows, the housing having a plurality of openings each of which communicates with the flow passage and functions as at least one of an inlet through which the fluid flows into the flow passage or an outlet through which the fluid flows out from the flow passage;
- and
- a first movable disk and a second movable disk provided to be aligned with each other in the axial direction while being spaced apart from each other inside the flow passage to divide the flow passage in the axial direction, the first movable disk and the second movable disk being configured to rotate along with rotation of the shaft,
- wherein the plurality of openings includes a plurality of one-side openings provided on one side in the axial direction with respect to the first movable disk, and a plurality of other-side openings formed on an other side in the axial direction with respect to the second movable disk,
- wherein the housing includes a one-side partition wall partitioning the flow passage on the one side in the axial direction with respect to the first movable disk into a plurality of one-side flow passages communicating with the plurality of one-side openings, and an other-side partition wall partitioning the flow passage on the other side in the axial direction with respect to the second movable disk into a plurality of other-side flow passages communicating with the plurality of other-side openings,
- wherein the first movable disk has a first through-hole penetrating through the first movable disk in the axial direction, and the first movable disk is configured to switch a flow passage, within the plurality of one-side flow passages, communicating with the plurality of other-side flow passages, by being caused to rotate along with the rotation of the shaft, and
- wherein the second movable disk has a second through-hole penetrating through the second movable disk in the axial direction, and the second movable disk is configured to switch a flow passage, within the plurality of other-side flow passages, communicating with the second through-hole, by being caused to rotate along with the rotation of the shaft.
