    摘要： Rotary valve system for controlling communication with a port in an internal combustion engine which, in one disclosed embodiment, has a crankshaft, compression and expansion pistons connected to the crankshaft for reciprocating movement within compression and expansion chambers, a combustion chamber in which air from the compression chamber is combined with fuel and burned to produce an increased gas volume. The valve system has an outer valve member which is rotatively mounted in a bore and has an opening which moves into and out of communication with the port as the outer valve member rotates, an inner valve member rotatably mounted within the outer outer valve member with an opening at least partly overlapping the opening in the outer valve member, a flange extending along one edge of the opening in the inner valve member and through the opening in the outer valve member for sealing engagement with the wall of the bore, and means for effecting rotation of the valve members to change the degree of overlap between the openings and thereby control the timing and duration of communication between the openings and the port.

    摘要： Constant pressure internal combustion engine having compression and expansion chambers of variable volume, an elongated combustion chamber of substantially constant volume between the compression and expansion chambers, and a fuel inlet for introducing fuel into the combustion chamber where it mixes with compressed air from the compression chamber to form a mixture of fuel and air that burns as it travels through the combustion chamber. In some embodiments, the combustion chamber is folded back upon itself and has a rough, twisting interior side wall, with long, sharp protrusions extending inwardly therefrom and forming hot spots which help to provide complete combustion of the fuel mixture throughout the combustion chamber. These protrusions, together with flow turbulators within the chamber, promote complete mixing and, hence, combustion of the fuel and air in the combustion chamber.
