Abstract
1344576 Diaphragm pumps DORR-OLIVER Inc 8 March 1972 [12 March 1971] 10718/72 Heading F1A In a gas or liquid pressure actuated diaphragm pump having a diaphragm 10 separating an actuating chamber 14 from a pumping chamber 13, a spring 32 is compressed during the discharge stroke by a rod 21 connected to the diaphragm, and effects or assists the suction stroke. The precompression of the spring is adjustable by nuts 34a, 34b to control the pump stroke and suction stroke acceleration. The stroke also may be limited by an adjustable stop engageable by the upper end of the rod, Fig.1a (not shown). An air-tight casing 23 surrounds the spring. A timer-controlled solenoid valve V-I controls fluid-flow to and from actuating chamber 14. An additional valve, Fig.4 (not shown), may connect vacuum to the actuating chamber for the suction stroke. In Fig.9 (not shown), a valve connects the actuating chamber to a pressurized liquid supply for the discharge stroke, the supply incorporating a pump and a pressurized tank.
