Abstract
1344668 Reciprocating pumps FICHTEL & SACHS A G 2 Dec 1971 [16 Dec 1970] 56098/71 Heading F1A In a radial piston pump comprising spring- loaded pistons 6 engaging an eccentric 2 via slippers 8, liquid is drawn into the cylinders 15 from eccentric chamber 3 via groove 10 in the eccentric and a passage through the piston, and is discharged via passages 28 and a common non-return valve 16, the piston passage being restricted by an orifice plate 9, such that above a predetermined speed the pump output is substantially constant. The shaft bearings are lubricated by liquid from chamber 3 via passage 13, chamber 30 and passages 11, 12 and 27. Valve 16 comprises an annular plate 22 loaded by a plurality of springs 23, and having an aperture aligned with discharge passage 21.
