Abstract:
1. A reciprocating air pump apparatus, comprising: a frame; a pump for compressing air through a series of linear close-strokes and open-strokes performed between a first portion that is fixed in position with respect to said frame and a reciprocating portion, and said pump having plural cylinders slideably and sealably engaged therein and arranged as multiple-chambers defining multiple-stages, and thereby enabling said series of close-strokes and open-strokes to compress air; a manifold, having an air inlet cavity with an inlet vent disposed on the exterior of said manifold, and having a compressed air outlet cavity formed therein with an outlet vent disposed on the exterior of said manifold; an outlet valve body disposed between said first portion of said pump and said manifold, and threadably engaged with said manifold, and having an outlet valve therein, which is pneumatically coupled to direct high-pressure compressed air into said outlet cavity, and having an inlet port formed therethrough to pneumatically couple inlet air from said inlet cavity, and wherein said inlet cavity and said air port are pneumatically coupled by an annular cavity defined between said manifold and said outlet valve body when threadably engaged together, and wherein said annular cavity is disposed about said outlet valve; a reciprocating linear drive having an electric motor, said drive fixed to said frame to deliver linear force to said reciprocating portion of said pump, and a control system coupled to said electric motor and operable to sequentially alternate the direction of force of said reciprocating linear drive, thereby enabling reciprocating application of linear force to said reciprocating portion.
