ABSTRACT:
An apparatus for moving a fluid medium comprising a positive displacement member movable to move the fluid medium and a drive mechanism adapted to be driven by a motor for driving the positive displacement member to move the fluid medium. The drive mechanism includes a wobble plate coupled to the positive displacement member for driving the positive displacement member. The drive mechanism is responsive to back pressure on the positive displacement member for adjusting the angle of the wobble plate to thereby change the volume of the fluid medium movable by the positive displacement member.
