Patent ID: 8439001

Claim:
An engine system comprising; a housing, a plurality of pistons disposed in said housing and reciprocally movable relative to one another to generate a reciprocating motion, a crankshaft disposed in said housing presenting a central axis, said crankshaft connected to said plurality of pistons thereby converting the reciprocating motion of said plurality of pistons into a rotational motion of said crankshaft; a plurality of plates having a planar configuration and being sandwiched by said side portions of each of said pistons, said side portions extending perpendicularly and outwardly from each of said plates thereby creating said vacuum inside said side portions; and each of said pistons presenting a plurality of side portions connected to one another to form a vacuum therein and movable relative to one another as each of said pistons is moved reciprocally between engaging and disengaging positions with one of said side portions connected to said crankshaft and extending in parallel and linearly plane and movable from said engaging position as said side portions abut one another to said disengaging position as said portions move away from one another thereby maintaining said parallel and linear plane between said side portions as said crankshaft rotates about said central axis.
