Abstract

759,086. Revolving-cylinder pumps. CAMBI IDRAULICI BADALINI SOC. PER AZIONI. May 12, 1954 [March 8, 1954], No. 13850/54. Class 102(1). [Also in Group XXIX] In a hydraulic pump the cylinder block 1 is driven from a shaft 8 through a splined coupling 9 and the end of the cylinder block is concave and spheric al and bears against a convex distributor valve 2. The pistons 5 have spherical ends which engage shoes 6 bearing on an inclined plate cam 7. The plane of the centres of the spherical ends of the pistons intersects the axis of the shaft 8 in the zone of the splined coupling 9.
