Abstract
A rotary valve is provided including a housing with an inner chamber having a first inlet, a first outlet, a second inlet, and a second outlet. A valve body is rotatably positioned in the housing. The valve body includes at least one isolated fluid pathway that, depending upon a rotational position of the valve body, provides at least one of a direct connection of one or more of the inlets to one or more of the outlets, or permits flow from at least an other one of the inlets or the outlets that are not in the direct connection created by the at least one isolated fluid pathway into or from the inner chamber. At least one actuator controls the position of the valve body.
Claims9
A rotary valve, comprising:
- a housing having an inner chamber;
- a first radial inlet, a first radial outlet, a second radial inlet, and a second radial outlet on the housing, and an axial inlet or outlet located on the housing that connects to the inner chamber;
- a valve body rotatably positioned in the housing that, dependent upon a rotational position of the valve body, provides at least the following conditions:
- (1) a direct fluid connection of a single one of the radial inlets to another adjacent single one of the radial outlets via a tubular isolated fluid pathway;
- (2) (a) the direct fluid connection of the single one of the radial inlets to another adjacent single one of the radial outlets via the tubular isolated fluid pathway, and (b) a fluid connection through the inner chamber between (i) a single one of the radial inlets or the radial outlets and (ii) the axial inlet or outlet;
- and
- (3) fluid connections through the inner chamber between (i) a first one of the radial inlets or the radial outlets, (ii) a second one of the radial inlets or the radial outlets and (iii) the axial inlet or outlet, wherein the direct fluid connection of the single one of the radial inlets to another adjacent single one of the radial outlets via the tubular isolated fluid pathway is blocked;
- and
- at least one actuator that controls the position of the valve body.
