Abstract

1,020,627. Reciprocating pumps. CESARE GALDABINI S.p.A. Feb. 11, 1964 [Feb. 20, 1963], No. 5601/64. Heading F1A. In an hydraulic reciprocating pump having a pulsating output, a number of cylinders are located about a restricted arc in a rotary cylinder block. In a seven cylindered pump, three adjacent cylinders deliver through conduits 6<SP>1</SP> to a delivery outlet in the delivery block 8<SP>1</SP> while the remainder deliver through conduits 9<SP>1</SP> into the delivery block. The pump, is driven by an electric motor via a flywheel 2<SP>1</SP> and the cylinder block is mounted on trunnions 14<SP>1</SP> for pivoting about a line 0. Since the drive to the block is transmitted through the pistons the full complement thereof is provided, whereas in an alternative radial embodiment, in which the cylinder block is directly coupled to the drive shaft, only four cylinders are provided (Fig. 5, not shown).
