    Abstract: In a tappet-driven single piston pump, piston side loads caused by return spring out-of- squareness are eliminated by effectively piloting the piston return spring, preferably the associated spring seat, by the tappet, thereby allowing the tappet to bear the spring side load. The piston engages and is returned by the spring seat, but radial clearance between the piston and spring seat is greater than radial clearance between the spring seat and tappet, thus eliminating side loading imparted to the piston. The spring seat can be considered a piston retainer, in which the piston is not closely attached to the retainer but instead exhibits a predefined radial clearance greater than the piloting clearance between the retainer and the tappet.

    Abstract: The invention concerns a pump for pumping a first liquid, called transferred liquid, and comprising a main unit (18) for pumping the transferred liquid actuated by an auxiliary unit (20) pumping a second liquid, called working liquid. The auxiliary unit (20) comprises a hub (64) mounted rotatable in a housing (16). Said hub (64) comprises a cylindrical guiding surface (SG) rotatable in the housing (16) extended by a shoulder (FE) axially positioning the hub in the housing (16). The guiding surface (SG) and the shoulder (FE) co-operate respectively with matching rotation guiding and axial positioning means (SP, FP) borne by the housing (16). The hub (64) is integral with a skew plate (62) actuating at least a piston (54) elastically returned towards said skew plate. The shoulder (FE) is urged to press against the matching means (FP) for axial positioning by the return force of the piston and the pressure of the working liquid in contact with the skew plate (62). The invention is applicable to a high pressure pump for supplying a motor vehicle engine with fuel.
