Abstract

1329051 Reciprocating pumps PHILIPS ELEC TRONIC & ASSOCIATED INDUSTRIES Ltd 21 May 1971 [25 May 1970] 16308/71 Addition to 1155826 Heading F1A [Also in Division G1] A hydraulic pump 29 comprises a cylindrical casing 35 connected by ball valves 31, 33 to pipes 9, 7. A bellows 37, mounted on the lid of casing 35, is contracted when a motor 55 drives a lever 44 through a rack and pinion, allowing liquid to enter casing 35 from pipe 9. When the motor is de-energized a spring 43 restores the bellows to its original position, forcing liquid into tube 7. A switch 61, operated by the lever 44 in the rest position, ensures that the motor 55 is not reenergized until the pump bellows is fully expanded. In use the motor 55 is fed with pulsating current to produce corresponding pulsating flow of liquid in tube 7.
