Abstract
1,167,224. Diaphragm pumps. LEWA HERBERT OTT. Feb.22, 1967 [March 1, 1966], No.8547/67. Heading F1A. In a hydraulically-actuated diaphragm pump comprising a diaphragm 7, Fig.1, reciprocated by a piston 10 of adjustable stroke acting through a liquid column in a chamber 5, a valve 18 releases excess pressure in chamber 5 to a reservoir 6, and is biased to its closed position by a spring 19 loaded by a hydraulic actuator 30 responsive to the pressure in the pumping chamber 4 or the delivery line 4a. The actuator 30, Fig.2, comprises a piston 33 acting through a rod 34 on spring 19, the initial loading on spring 19 being adjusted by a threaded sleeve 20, and the maximum loading of the spring by piston 33 being adjustably limited by a threaded sleeve 39. The connection 31 to actuator 30 incorporates a check valve 47 and an adjustable throttle 45, both of which may be omitted when the actuator is connected upstream of pump delivery valve 13. An adjustable make-up valve 14, Fig.1, controls flow from reservoir 6 to actuating chamber 5.
