Abstract
A radial piston pump in which the sliding shoe has a central region that engages the driven end of the piston and an outer region or rim surrounding the driven end of the piston and projecting into the pumping chamber bore a distance such that for all positions of the piston relative to the drive member, at least a portion of the outer region of the shoe remains within the pumping chamber bore. In another aspect, the invention is directed to a sliding shoe for a radial piston pump, wherein the shoe has a concave bottom side, a socket portion projecting centrally on the top side, and a plurality of guide arms projecting upwardly on the top side and spaced laterally from the socket portion. Preferably, the projecting rim is in the form of guide arms that are spaced apart to form a castellated, substantially annular rim around the socket portion.
