Abstract
A hydraulic pump having one or more pistons which are moved backwards and forwards by one or more spherical eccentrics, in which the contact between a spherical eccentric and the spherical head of each piston is ensured by means of a sliding shoe has the geometric axis of each piston (13) set over against the mid plane of the ball of the eccentric (4). The mind plane of the eccentric runs vertical to the geometric axis of the drive shaft (3). The displacement of piston (13) axis and mid plane is such that the sliding shoe is constantly rotated in a uniform motion.
