Abstract
A combination reciprocating piston device, such as an internal combustion engine, and a rotary machine of the intermeshing gear type, such as a hydraulic pump, are afforded in a compact arrangement that eliminates the need for separate crankshafts or separate rotary machine rotors. This reciprocating piston machine operates with a pair of oppositely rotatable crankshafts which are drivingly connected to the piston such that the piston reciprocates in its cylinder in a true straightline motion. The crankshafts are respectively provided with a pair of balance gears which directly intermesh with one another to coincide the rotational movement of the crankshafts. The balance gears also serve as the rotors for a rotary fluid machine in which the lobes of the rotors provide positive fluid displacement.
Claims10
A combination piston engine and rotary machine comprising:
- a piston reciprocally movable in a cylinder having fluid inlet and outlet connections thereto, a pair of oppositely rotatable crankshaft means disposed on opposed sides of the longitudinal axis of said cylinder within a crank case, each crankshaft means having an element intersecting with a longitudinal plane of said cylinder, a one-piece translator connected to said piston, engaged by said elements and disposed in said longitudinal plane extending from said cylinder into said crank case for moving in a true straight line motion along said longitudinal axis, and a rotary unit comprising a pair of intermeshing gear wheels disposed in an enclosed casing separate of said crank case and connected to said elements for coinciding the rotation of said pair of crankshaft means, said casing having fluid inlet and outlet connections thereto, whereby said rotary unit functions to coincide the rotation of said engine crankshaft means and operate as an expansible-chamber, fluid machine.
A rotary fluid machine comprising a pair of wheels of intermeshing gear configuration, said wheels disposed in a housing having fluid inlet and outlet connections thereto, said wheels connected respectively to a pair of oppositely rotatable crankshafts operatively connected to a piston reciprocally movable in a cylinder, wherein said crankshafts are contained in a crankcase and said wheels are contained in a chamber defined by said housing separate of said crankcase.
