Abstract
A radial piston pump has a housing, a shaft mounted for rotation in the housing and including an eccentric provided with a cam track, inlet and outlet ports in the housing, valve means installed in the ports, a plurality of radially reciprocable pistons spaced about the eccentric and each having a radially inner surface in sliding engagement with the cam track, and a layer of synthetic plastic material having a low coefficient of friction on each of the surfaces, so as to reduce friction between the same and the cam track.
