Abstract

1508665 Reciprocating pumps N BRUNDJERG 27 June 1975 [27 June 1974] Heading F1A A pump, e.g. for concrete, comprises a pumping piston 2, e.g. driven pneumatically or hydraulically, controlling an inlet port 8 and a piston 4 connected to the end 6 of the cylinder 1 by a compression and tension spring 5 and controlling an outlet port 9, the face of piston 4 being substantially flush with the edge of inlet port 8 in one extreme position of piston 4, as shown.
