    Abstract: A three-position stop type swing actuator has a main piston freely moving in forward and backward directions in an axial direction within a casing, an output shaft placed at a coaxial position with the main piston in such a manner as to be fixed in an axial direction and freely rotate around an axis, a conversion and transmission mechanism converting a forward and backward motion of the main piston into a rotating and swinging motion of the output shaft, and a sub piston having a stroke smaller than that of the main piston a fluid pressure operating force larger than that of the main piston and arranged within the casing in such a manner as to freely move in the forward and backward directions and be capable of being brought into contact with the main piston so as to restrict a middle stop position of the main piston.

    Abstract: A rotary disc having at least two radial concave portions and two radial convex portions on one end is opposed at the concave/convex surface to a concave/convex surface of a non-rotary disc having the concave/convex surface of the same shape, and one of the discs is made axially slidably and engaged to the other resiliently. Two variable volume chambers formed between the concave/convex surfaces of the two disc are used as a set of engine chambers in which a suction port is disposed to a slope of the first chamber on the side that the concave/convex surfaces of discs get into engagement, and the exhaust port is disposed to the slope of the second chamber on the side that the concave/convex surfaces of discs get out of the engagement. A gas reservoir combustion chamber communicating by way of a compression communication channel is disposed between the first chamber and the second chamber, and the compression stroke and the exhaust stroke are conducted simultaneously, while the expansion stroke and the suction stroke are conducted simultaneously in the two concave portions of the rotary disc passing through the two chambers.

    Abstract: A rotating cylindrical piston engine with a variable effective compression stroke. The present engine shuttles the piston during the power stroke as far as possible in the cylinder to maximize the use of the power provided by the fluid explosion. Since as much as possible of the explosion force is used, i.e., preferably until the exhaust gas reaches ambient temperature or pressure, the exhaust gas is cooler and thus the engine may need no external water cooling, allowing internal air cooling in the cylinder by intake air to be complemented by the cooling with the exhaust gas. Preferably, such linear motion of the shuttling piston over such a great length is converted to rotary motion by forcing the piston to spin in the cylinder as the piston is driven the length of the cylinder. The relative great length of the stroke of the piston captures a great amount of air during the intake stroke, and some of this intake air is expelled during the compression stroke to provide for an effective compression stroke such that the power stroke is of a greater length than the effective compression stroke. The present engine further includes a plate-like cylinder head, a plate like rotary valve, and plate like manifold to provide for a compact head arrangement. The present engine further includes a compression release port which may be opened during the power stroke to permit the piston to act like a brake relative to the power output shaft. The present engine further includes a track and rider arrangement for converting the linear shuttling motion of the piston into rotary motion. The present invention further includes a gear assembly between the piston and a power output shaft for transmitting the rotary motion of the piston to the power output shaft. The present engine further includes a fuel pump assembly, a timing assembly, and an engine isolation arrangement.

    Abstract: A double-acting, rotating piston reciprocating in a cylinder with the motion of the piston providing the valving action of the Sibling Cycle through the medium of passages between the piston and cylinder wall. The rotating piston contains regenerators ported to the walls of the piston. The piston fits closely in the cylinder at each end of the cylinder except in areas where the wall of the cylinder is relieved to provide passages between the cylinder wall and the piston leading to the expansion and compression spaces, respectively. The piston reciprocates as it rotates. The cylinder and piston together comprise an integral valve that seqentially opens and closes the ports at the ends of the regenerators alternately allowing them to communicate with the expansion space and compression space and blocking that communication. The relieved passages in the cylinder and the ports in the piston are so arranged that each regenerator is sequentially (1) charged with compressed working gas from the compression space; (2) isolated from both expansion and compression spaces; (3) discharged of working gas into the expansion space; and (4) simultaneously charged with working gas from the expansion space while being discharged of working gas into the compression space, in the manner of the Sibling Cycle. In an alterate embodiment, heat exchangers are external to the cylinder and ports in the cylinder wall are alternately closed by the wall of the piston and opened to the expansion and compression spaces through relieved passages in the wall of the reciprocating, rotating piston.

    Abstract: A piston-type power generating machine, useful as a prime mover, internal combustion engine, pump or the like, is disclosed wherein a piston having an eccentric center of gravity with respect to its longitudinal axis is reciprocatingly guided in a cylindrical working chamber of a machine housing. The piston is connected to output conversion gears through guide slots by means of output members which penetrate the housing and which impart a rotational movement to the piston about its longitudinal axis.
