Abstract
A radial piston pump having a drive shaft with camlike protuberances. The pump has a plurality of pistons movable in the radial direction, and one plate is retained on the end of each piston to engage the drive shaft. One or more recesses are disposed in the plate facing the piston, the recesses are engaged by snap hooks on a plate retainer on the piston. In a first variant a blind bore with a circumferential groove recessed out of the middle of the plate facing the piston is engaged by a snap ring retained in a notch on the piston. In a second variant a blind bore is recessed out of the plate facing the piston, and two parallel bores extend transversely to the blind bore, the center lines being tangent to the blind bore, and the bores receive two pins, which engage a notch on the piston.
