A rotary valve includes a rotary component configured to rotate about an axis of rotation thereof. The rotary component includes a plurality of fluid openings formed at an exterior surface thereof with each of the fluid openings forming a fluid inlet or a fluid outlet into one of a plurality of fluid passageways formed through the rotary component. The rotary component further comprises a valve body rotatably receiving the rotary component therein. The valve body includes a five fluid ports formed therethrough with each of the fluid ports configured to be selectively aligned with one of the fluid openings of the rotary component depending on a rotational position of the rotary component relative to the valve body to allow the rotary valve to operate as a five-way switching valve.
A rotary valve comprising:
The rotary valve of 9, wherein the plurality of fluid passageways include a first fluid passageway fluidly coupled to each of the first circumferential fluid opening of the first tier and the first circumferential fluid opening of the second tier, a second fluid passageway fluidly coupled to each of the second circumferential fluid opening of the first tier, the third circumferential fluid opening of the first tier, the second circumferential fluid opening of the second tier, the third circumferential fluid opening of the second tier, and the fourth circumferential fluid opening of the second tier, and a third fluid passageway fluidly coupled to each of the fifth circumferential fluid opening of the second tier and an axial fluid opening of the plurality of the fluid openings formed through an axial end wall of the rotary component.
The rotary valve of 14, wherein the five of the fluid ports includes a first inlet port, a second inlet port, a first outlet port, a second outlet port, and a third outlet port, wherein a first mode of operation of the rotary valve includes the first inlet port fluidly coupled to the first outlet port and the second inlet port fluidly coupled to the second outlet port, a second mode of operation of the rotary valve includes the first inlet port and the second inlet port both fluidly coupled to the first outlet port, a third mode of operation of the rotary valve includes the first inlet port and the second inlet port both fluidly coupled to the second outlet port, and a fourth mode of operation of the rotary valve includes the first inlet port fluidly coupled to the third outlet port and the second inlet port fluidly coupled to the second outlet port.
