ABSTRACT:
Controls for operating fluid pressure fueled reciprocating piston engines are simplified by passing fuel directly to a cylinder inlet port from a synchronously timed rotary distributor. This permits a snap acting diaphragm transfer valve normally opening the inlet fuel path to the cylinder to respond to a decrease in fuel pressure to quickly snap open an exhaust port and close the inlet port. Several embodiments include a battery operated fuel supply source, recycling of spent fuel, and auxiliary exhaust paths from bottom dead center cylinder positions, to increase efficiency, speed and reliability.
