Abstract

PURPOSE: To secure stabilized operation by providing a selector valve of simple composition to a pump having fear of generating seizure out of two pumps driven by a common driving source and automatically feeding it with a liquid in a quantity required for preventing the seizure.
CONSTITUTION: When the oil pressure at the outlet 11 of a pump P2 does not reach a given pressure level, a selector valve 13 constituted in such a manner that it performs selecting operation of communication and checking automatically according to the outlet pressure of the pump P2 is moved toward an inlet 9 by a spring 16 and a passage 15 communicates the outlet 8 of a pump P1 with the inlet 9 of the pump P2, thereby a part of discharged oil at the outlet 8 being directly supplied to the inlet of the pump P2 and thus the baking being prevented. And, when the discharge oil pressure at the outlet 11 of the pump P2 reaches a given pressure level, it acts on a raised part 14, which moves the selector valve 13 to the right, thereby the opening communicating with the inlet 9 of the passage 15 being closed and the direct supply being intercepted.
