Abstract

The oil pump has an uneven number of cylinders arranged in a drum pattern round a spindle, with double-acting cylinder plungers driven by a single driving member engaging the end of the plunger rods in a plane at a constant angle to the drum axis. The drum and the driving member rotate in relation to each other on the drum axis, being driven by an engine or motor. The driving member is a sleeve (10) rotated coaxially to the drum and incorporates a cylindrical socket (15) on an axis inclined to the drum axis. A swashplate spider (20) has spherical bosses (122) spaced round the periphery and fitted in annular sockets formed in the ends of the plunger rods and also a cylindrical trunnion (24) fitting in the sleeve socket (15). The drum axis passes through the spider centre.
