Abstract

1,212,647. Valves. GEWERKSCHAFT EISENHUTTE WESTFALIA. 21 Feb., 1969 [8 Oct., 1968], No. 9420/69. Heading F2V. A pit-prop control device has a fluid pressure admission valve 10 and a fluid pressure exhaust valve 21 both of which are actuated through plungers 12, 24 by a spring-biased cam that is reciprocated by a compressed air motor (15) and is provided with laterally-offset oppositelyinclined cam surfaces 18, (23). Opposite movements of the cam respectively connect the inlet P to the outlet St via check valve 19 and the outlet St to the return R. The exhaust valve 21 is pressure balanced by a piston 25 on which outlet fluid pressure acts via passage 26.
