Abstract

1,227,159. Reciprocating pumps. A. H. CROUCHER. Aug. 8, 1969 [Nov. 18, 1968J, No.54634/68. Heading F1A. An apparatus for metering quantities of flowable material comprises two double-acting pumps 17 and 18 driven by hydraulic ram 14, the working members of the pumps being linked so that their relative delivery volumes may be varied. A manually variable pump 3, driven by a motor 2, supplies fluid via a change-over valve 11 to drive the ram, the valve being actuated by microswitches 16 co-operating with an extension 15 of the ram at the end of each stroke. A slide 20 fixed to the working member of the pump 17 is driven by the ram, and a rocking member 22 is pivotally attached to the slide 20 and a slide 21 on the working member of pump 18. Rollers 25 between trunnions 26 slidably mounted on a frame 27 from a variable fulcrum for the rocking member 22, the fulcrum being adjusted by means of a screw 28. The output of the pump 3 may be varied by operating a lever 4 and more than two pumps similar to 17 and 18 may be used. The apparatus is especially useful for metering viscous liquids.
