Abstract

An oiler pump (50) comprises, a housing defining a cylinder (80) and a chamber (82), a manually displaceable piston (120) received in the cylinder (80), a spring (110) in the chamber (82) between the housing and the piston (120), a first one-way check valve (90) on a first end of the piston (120), a second one-way check valve (100) on the housing, and a fluid displacement member substantially completely filling the chamber when the piston is in a retracted position and to substantially completely open the chamber when the piston is in the first position. The fluid displacement member is formed by an outer skirt member and an inner guide member formed integrally with the piston member (120). The fluid displacement member increases the priming height and efficiency of the pump by reducing the volume area in the chamber in the fully compressed state which might accumulate gas to zero.
