Abstract
891,775. Valves. SEABORNE, T. L. April 5, 1960 [June 24, 1959], No. 21710/59. Class 135. A vacuum compensator relief valve 6, spring or weight loaded at 12 is opened by air pressure acting on primary and secondary pressure responsive means for small vacuum fluctuations and on tertiary means for large openings to compensate large fluctuations. For small fluctuations air enters through openings 18 adjustable by rotation of sleeve 13 and acts primarily on the area of valve 6 and, by deflection in seat recess 8, secondarily on disc 9 attached to the valve 6. Larger fluctuations produce a pressure reduction in the valve inlet chamber 30 so that atmospheric pressure acting via sleeve openings 23 on the bottom of piston 20 opens the valve still further. A plastic disc 15 sliding within the sleeve 13 damps valve movement. A rubber cap 26 seated on top of the valve has a stopper 27 sealing a casing opening 24. The cap may be reversed so that a narrow stopper 28 no longer obturates the opening 24 but extends therethrough to hold the valve closed and a metering opening 29 allows sufficient air to pass to test the reserve vacuum in the milking machine.
