ABSTRACT:
The pump is formed by a body having a cavity with a cylindrical chamber in which a piston is reciprocated toward and away from an inlet and outlet aperture. A crank shaft extends through an aperture formed through the piston transverse to its axis and through opposite walls of the cavity. The crank shaft has a cam located in the piston aperture. Upon rotation of the crank shaft, the cam alternately engages opposite facing cam surfaces of the piston in the piston aperture to reciprocate the piston to draw fluid into the chamber from an inlet path and then to pump the fluid out through an outlet path. The piston has spaced apart O-rings on its outer wall which engage the chamber wall upon reciprocation of the piston.
