ABSTRACT:
A linear engine/hydraulic pump system provides an efficient source of controllable fluid power thay may be used for a hydrostatic drive system of a vehicle. The engine/pump has a prompt first stroke full power capability and capability of prompt power increase from a lower power operation. A supplemental engine (bounce engine) produces output work to operate the power engine of the free piston engine pump during a compression stroke of the latter. The engine is of the opposed piston type with a synchronizer and cross drive to maintain controlled interrelated operational movement of the two oppositely moving pistons thereof while combining output work effort and holding approximately constant the approximate center of mass of the engine. A novel starter also is disclosed.
