Abstract
A selector valve assembly controlling the flow of different flow paths of fluid. The assembly includes a body member having a compartment with an end wall, an outlet passage in the end wall, two ports connected to the body member and communicating with the outlet passage in the end wall, and two passages communicating with the compartment. A rotatable member is sealable positioned in the compartment and has a side wall and an end wall. A first passageway extends a distance into the rotatable member from the end wall thereof and a second passageway extends through the side wall thereof and communicates with the first passageway. Rotation of the rotatable member selectively orients the second passageway with each of the two passages to cause liquid in the two passages to pass to the first and second passageways and subsequently to the outlet passage and at least one of the ports.
