ABSTRACT:
A pneumatically actuated lubricant pump wherein air is forced into the cylinder through a passage extending longitudinally through the piston rod. The rod is part of a piston assembly reciprocably mounted within a pump housing. The air passage extends from a lateral rod entrance through the rod and through the piston head. Air is forced into and released from the air cylinder through the passageway. In an alternative double-action embodiment, a second air flow passage extends through the pump housing alone directly to the air cylinder permitting compressed air to be alternately supplied to the opposite sides of the piston head.
