Abstract
A rotary valve with ports connected to housing. A first valve body rotatably positioned in a housing flow chamber has a fluid pathway that connects a first and/or second port to the flow chamber in a first rotational position, and prevents flow from the first and/or second port in a second rotational position. A second valve body rotatably positioned in the flow chamber has at least one fluid pathway that connects a third and/or fourth port to the flow chamber in a first rotational position, and prevents flow from the third and/or fourth port in a second rotational position of the second valve body. An actuator positions of the first and second valve bodies, and includes an epicyclic gear arrangement for driving the second valve body such that movement of the actuator shaft that rotates the first valve body results in only a partial movement of the second valve body.
