ABSTRACT:
A pump actuated by a reciprocal oscillating motion, the pump including a casing member enclosing an elongated substantially cylindrical chamber therewithin, a pair of flexible bellows disposed at the opposing distal ends of the chamber, each of the bellows, in a normal unflexed state, extending inward into the chamber, and each of the bellows enclosing a pumping chamber, each of the pumping-chambers having a one way intake port and a one way output port, a piston positioned within the chamber for reciprocation therewithin under the influence of gravity in response to the reciprocal oscillating motion, the piston including a substantially spheroid member, the piston having a reciprocal stroke such that, at the extremes of the reciprocal stroke, the piston alternately compresses each of the flexible bellows, thereby alternately decreasing the volume of each of the pumping, and a cap member disposed at each of the distal ends of the casing member, each of the cap members abutting one of the flexible bellows to thereby enclose the pumping chambers between the cap members and the flexible bellows.
