ABSTRACT:
A diverter valve assembly arranged and constructed to be coupled in fluid communication between fluid inlet and a pair of outlet openings for normally conducting fluid through one outlet until the other outlet is opened, to automatically divert the fluid to the other outlet. The assembly comprises a housing having first and second spaced chambers. A conduit interconnects the first and second chambers and is provided with at least one port for conducting fluid from the first chamber to the one outlet. A tubular member is positioned in the conduit and is adapted to reciprocate therein when the other outlet is opened and closed. Means is coupled to the tubular member and positioned within the first chamber to provide a fluid tight seal when the other outlet is opened, and to prevent flow of fluid through the one outlet. Piston means is disposed in the second chamber and is coupled to the other end of the tubular member, so that when the other outlet is opened and closed, the tubular member is reciprocated by the change in fluid pressure. Also valve means may be associated with the seal means and the tubular member to prevent a backflow of fluid to the inlet opening when reduced pressure occurs within the first chamber.
