Abstract
A system includes a crank, a motor coupled to rotate the crank, a swash plate coupled with the crank, a plurality of cylinders, a plurality of pistons moveable in the cylinders, and a plurality of cranks rods. The crank rods couple the pistons by ball joints with the swash plate. Rotation of the crank causes reciprocating movement of the swash plate, the crank rods, and the pistons, and the reciprocating movement of the pistons pumping a fluid through the fluid inlet to the fluid outlet.
