ABSTRACT:
An engine for driving the compressor of an air conditioner system which is powered by the heat of the exhaust manifold of a vehicle internal combustion engine. The engine of the invention includes a closed cylinder with a piston dividing the cylinder into two compartments, and with the piston rod extending beyond one end of the cylinder to power both the air conditioner compressor pump and a liquid pump that supplies the engine with pressurized liquid. The inlet port of the engine is located on a cylinder wall midway between the cylinder ends, with bores in the piston linking the inlet port with each cylinder compartment at the position of the cylinder that reduces the particular compartment to its minimum volume. Each end of the cylinder is surrounded by a heated exhaust jacket so that the liquid fed into the cylinder compartment is vaporized to expand the cylinder compartment and drive the piston. An exhaust port extends from each cylinder end with each exhaust port blocked in turn by a slide rod that extends axially through the cylinder and into each exhaust port. A piston is fixed to the slide block in an auxiliary cylinder chamber inside the piston so that the pressurized gas in one engine cylinder compartment is led by ports in the piston to one of the two auxiliary cylinder compartments to maintain the slide rod in bearing engagement against the exhaust valve opening leading from the pressurized engine cylinder compartment until the piston reaches the end of the expansion stroke. The exhaust gas of the engine is led through a condenser, with the condensate led through the liquid pump and a cooler to the intake port.
