ABSTRACT:
A no-drip valve apparatus for regulating a fluid flow from an inlet to an outlet. A pressure activated supply valve means controls the flow of fluid through the valve. A partition member cooperates with a vacuum chamber to retract and retain any remaining oil in the valve or the oulet nozzle when the pressure activated supply valve means cuts off the flow of oil through the valve. The partition member is resiliently displaced by pressure fluid from a supply chamber adjacent the inlet and is displaced in one direction prior to flow of fluid to the outlet and is displaced in the other direction upon termination of the flow of fluid through the outlet.
