Abstract
A switching valve includes a base having a bottom wall. The switching valve includes a body that couples to the base to define a cavity between the body and the bottom wall. The body includes through holes that are each fluidly coupled to the cavity. The switching valve includes a driven slider set disposed within the cavity and having sub-sliders evenly distributed about the base. The switching valve includes driving rods each movably coupled to one of the through holes of the body. Each driving rod moves in a linear direction relative to the through holes to block or unblock each through hole. Each sub-slider slides in a linear direction responsive to movement of the driving rods. Only one through hole is unblocked at one time.
