Abstract

1,005,131. Reciprocating pumps. PRESNA MECHANIKA, NARODNY PODNIK. June 26, 1963, No. 25441/63. Heading F1A. [Also in Division F2] A diaphragm pump is actuated by a variable throw crank comprising a crankpin 9 hinged to webs 8, 10 in turn hinged to shaft members 11, 12 mounted in bearings 1, 2 which are slidable towards and away from each other together with the members 11, 12 to vary the throw of the crank.
