Abstract
A double acting dual stroke fluid pump with pressure assists is disclosed. First and second pistons are mounted to a common shaft which reciprocates within first and second cavities during compression and suction strokes. The second piston may have a one way valve which opens and closes during the compression and suction strokes to enable the fluid pump to force fluid out of the outlet during both the compression and suction strokes.
