Abstract: The present invention is for a means for transmission of force whereby linear movement is transferred into rotating movement or reverse. The invention is primarily intended to be used by combustion engines. The invention is for a means to transmit force between a forward and backward movement and a rotating movement by means of a ballbearing which runs in several tracks comprising a ball which is surrounded by ballholder which is fixed onto a piston rod for each respective ball or corresponding device for transmission of the linear movement. Fixed connected to each piston (4,5) is a piston rod (6,7) which in its opposite end has a holding device (17,18) for the ball (15,16) through which the force from the forward and backward movement is transmitted to the rotating disc (13). The balls (15,16) also serve as bearing between the stationary disc (8) and the rotating disc (13).

Abstract: A rotary internal combustion engine of the type having pistons mounted for reciprocatory movement in respective cylinders which are arranged in equally-spaced relationship around a longitudinal axis of rotation, said axis being the axis of rotation of an output shaft passing rotatably and sealably through apertures of respective first and second end plates of a housing within which the pistons and cylinders move as part of a rotatable rotor assembly secured to said output shaft, while the pistons are simultaneously movable reciprocably in the cylinders, cam follower means being associated with each piston and adapted to coact with undulating cam track means around the housing. Cyclical combustion of fuel in the cylinders imparts reciprocation to the pistons with resultant thrust against the cam track means so as to cause rotation of the rotor assembly and output shaft.

Abstract: A rotary power device of modular construction is disclosed in which one or more pistons are reciprocably received in a cylinder sleeve, and the sleeve is rotatably supported in a bore within a housing. A cam and follower mechanism acting between the housing and piston governs reciprocating motion of the piston(s) within the sleeve. Rotary power can be extracted from the sleeve, or reciprocating power can be extracted from the piston(s). The rotating cylinder functions as a sleeve valve and permits, depending on the porting, use of the device as a gas-expansion engine (e.g. steam or compressed air) or pump, or as a two-stroke or four stroke internal combustion engines using spark or compression ignition. Engines built according to the invention are simples, compact, and can be perfectly balanced, and multiple engine modules may be coupled together in various configurations to form power plants of various sizes.

Abstract: A radial piston engine comprising: a housing, an annular cam disk fixedly mounted in said housing, a cylinder block rotatably mounted about an axis with respect to said cam disk, a plurality of bores arranged in said cylinder block in a position radially with respect to said axis of rotation, a plurality of pistons respectively mounted in said bores, and cylindrical rollers for supporting said pistons on said cam disk, said rollers having axes which extend parallel to the axis of rotation of the cylinder block, and wherein said bores of said cylinder block which are adapted to receive and pistons are provided with recesses in the area of movement of said rollers, so as to receive sections of said rollers on both endfaces of said rollers.

Abstract: A self-propelled vehicle includes a body and a set of four internal-force generating devices, in the form of radial piston engines. Each device has a central axis about which some internal portions rotate. The four devices are configured in two opposed pairs, the two devices of one pair having parallel axes but turning in opposite directions, the two devices of the other pair also having parallel axes but turning in opposite directions. The axes of one pair are at right angles to the axes of the other pair. Each device provides an eccentric orbit for each of three pistons about a central axis the piston cylinders being defined by a rotor which rotates uniformly about that axis. As a result, the angular momentum and resulting centrifugal effect generated within each cylinder at its furthest displacement from the axis is significantly greater than the angular momentum and centrifugal effect when it is at its closest approach. The difference in these two effects is utilized to generate lift.

Abstract: A rotary internal combustion engine comprising a rotatable gear ring disposed between axially spaced first and second casings, the gear ring having teeth disposed internally thereon, piston-cylinder units fixed to the gear ring and moveable therewith, first and second annular cam rings mounted in the first and second casings, respectively, and rotatable in the same direction as the gear ring, the cam rings being in engagement with piston portions of the piston-cylinder units, and a drive gear having teeth interconnected with the gear ring and rotatable responsive to rotation of the gear ring, the speed of the cam rings being selectively variable to selectively vary the speed of the compression strokes of the engine.

Abstract: Rotary power engines driven by explosive or expansive media have pistons which reciprocate in cylinder cavities of a rotor at opposite sides of the rotor axis and which contact the walls of a stator by means of rollers. The rotor is turned by the reactive force of the pistons on the stator and by the reactive force of the working medium which exhausts from the cylinders as jets. In an internal combustion embodiment, one set of cylinders is used for compression of the working medium, and the compressed medium is transferred cyclically to adjoining cylinders for driving the rotor.

Abstract: This invention provides a power converting device capable of use as a pump and as a motor. The device includes a rotor shaped like a disc and secured to a shaft about which it rotates. Provided in the rotor are a plurality of piston chambers extending from the outer circumferential surface inwardly at an angle to a radiant from the axis. Each of the chambers opens through both side walls of the rotor, and each contains a piston. Each of the pistons is pivoted on either side to an arcuate drive segment adapted to move around an annular recessed channel within structure which defines a stationary enclosure for the rotor. There are two annular recessed channels, one on either side of the rotor, and the channels are aligned with each other and eccentrically located with respect to the axis of the rotor. With this arrangement, rotation of the rotor within the stationary enclosure is simultaneous with reciprocatory movement of the pistons in their respective piston chambers.

Abstract: A rotary engine for two cycle operation having arcuate combustion chambers formed in a rotor and correspondingly arcuate pistons mounted for swinging reciprocation in the combustion chambers on connecting rods pivoted to the rotor. The housing contains the rotor and provides an oblong inner periphery forming a raceway for cam followers mounted on the pistons so that, when ignition of the fuel mixture occurs at the beginning of a power stroke, the pistons are forced outwardly against the relative incline of the raceway in such a manner as to cause the pistons to impart rotary motion to the rotor. At about the end of the power stroke, the movement of the rotor causes recesses formed in the rotor at the inner end of the combustion chamber to communicate with exhaust and intake ports formed in the housing on opposite sides of the rotor for venting the spent gases through one of the recesses and receiving a fresh charge of fuel mixture under pressure through the other recess in a scavenging fashion.

Abstract: A rotary internal combustion engine comprising a generally cylindrical stator member having two pairs of sockets located in the periphery thereof, and a rotor member mounted to rotate about the stator member. Two pairs of opposing wedges are pivotally mounted at their vertices on the periphery of the stator member to pivot in and out of respective ones of the sockets as the rotor member is caused to rotate about the stator member. The rotor member has side walls and an interior peripheral wall which, in cooperation with the periphery of the stator member and the two pairs of pivotal wedges, define a combustion cavity and a compression cavity there between. The combustion cavity and compression cavity are disposed on opposite sides of the stator member adjacent the periphery thereof.
