摘要： A variable compression piston assembly includes a plurality of pistons, a transition arm coupled to each of the pistons, and a rotating member mounted for pivoting movement to slide along an axis of the drive member. Movement of the rotating member relative to the drive member changes the compression ratio of the piston assembly. An engine assembly includes first and second piston assemblies mounted back-to-back and 180° out of phase. A joint for positioning between first and second pistons includes an outer member and an inner member. The outer member is configured for movement relative to the pistons along a first axis perpendicular to the common axis of the pistons. The inner member is mounted within the outer member for rotation relative to the outer member about a second axis perpendicular to the first axis and the common axis.

摘要： A hydraulic pump includes a housing, at least two pistons mounted to the housing to rotate relative to the housing, and a transition arm coupled to each of the pistons to rotate therewith. The transition arm is set at a predetermined angle relative to a longitudinal axis of the pump. An adjustment mechanism sets the transition arm at the predetermined angle. A cylinder is mounted within the housing to rotate relative to the housing and defines pump cavities for receiving the pistons. A face valve defines inlet and outlet channels in fluid communication with the pump cavities. An apparatus for varying the output volume of a piston assembly includes at least two pistons, a transition arm coupled to each of the at least two pistons, and a rotatable member. The transition arm includes a nose pin, and the rotatable member is coupled to the transition arm nose pin. A radial position of the nose pin relative to an axis of rotation of the rotatable member is adjustable while the rotatable member remains axially stationary.

摘要： A reciprocating engine comprising a cylinder assembly having a pair of connected pistons for reciprocation therein, a drive ring having a rotational orbit substantially encircling the cylinder assembly and a power transfer mechanism for coupling and converting reciprocating motion of the piston to rotating motion of the drive ring. The engine with drive ring can be more compact than an equivalent conventional engine with crankshaft, can generate higher torque and can be subject to less cylinder wall wear due to side thrust of the pistons.

摘要： A flexible line trimmer is powered by a two-stroke internal combustion engine. The engine is scavenged in a uniflow fashion and has a scavenging cylinder and an exhaust cylinder connected by a common combustion chamber. Each cylinder has a piston turning one of two cantilevered crankshafts that are geared through adjacent counterweights having integrally formed teeth. The crankshafts extend in opposite directions for self-balancing. One crankshaft is coupled to a flywheel fan and other coupled to a starter. A fuel and air mixture is transferred to a common crankcase for the crankshafts through an intake port located on the exhaust cylinder. The piston of the scavenge cylinder is retarded with respect to the exhaust cylinder. An exhaust window opens prior to a scavenge window. The scavenge window closes after the exhaust window. The exhaust window is shortened to improve crankcase compression. The cylinders are joined in a siamese fashion, fabricated from a single piece, and skewed toward each other. A carburetor and muffler are mounted on substantially opposite sides of the exhaust cylinder.

摘要： Disclosed is a hydraulic motor with a nutating member. The nutating member mounted for nutation on a spherical surface bearing which in turn is mounted on a casing, has first and second bevel gears on respective end faces thereof, the first bevel gear on one end face being in mesh with a bevel gear rigidly mounted on the casing while the second bevel gear on the other end face being in mesh with a bevel gear carried rigidly by a shaft. A swash plate mounted on the casing for coaxial rotation with the shaft has an inclined end face against which said one end face of the nutating member is made to contact and being pressed thereagainst under the forces of pistons so that the swash plate with the inclined end face is caused to rotate, whereby the nutating member is made to nutate. Such nutation of the nutating member due to extension and retraction of the pistons under hydraulic pressure in a predetermined sequence results in the rotation of the shaft or the casing with respect to each other.

摘要： A fluid driven mechanism in the form of a fluid motor or fluid pump which is transmissionless, wherein speed and power are selectively varied by the operator through corresponding adjustment in the orientation of angularly disposed power transmitting structure. A large capacity unrestricted rotating fluid distributor vortically and cyclically directs ingress fluid successively to a series of pistons which is power-related to the power transmitting structure. The fluid distributor is uniquely caused to float during its rotation by oppositely imposed fluid under pressure within aligned eccentric chambers, each chamber being formed partly in the rotating distributor and partly in adjacent stationary structure.

摘要： An internal combustion engine in which the longitudinal center line of the cylinders are parallel to and equally spaced around the longitudinal center line of the engine.The pistons, working within said cylinders, are mounted on a swash plate mechanism, by means of which the reciprocating motion of the pistons is translated into the rotary motion of a carrier plate to which the said swash plate is mounted and, from which, is taken the drive into the vehicle transmission.Said swash plate is mounted on a post at the circumference of the carrier plate and pivots around said post when moved, on a longitudinal axis, by a mechanism.As each piston, in turn, passes the point on the swashplate adjacent to the mounting post, it is at the top-dead-center position in its cylinder. As said piston passes the diametrically opposite point on the swash plate it is at the bottom-dead-center position.When the swash plate angle is changed, by moving said mechanism, the bottom dead center position is changed thus causing the stroke of the piston to be changed.A circular form cylinder head contains a combustion chamber for each cylinder and a disc, driven by a forward projecting shaft mounted on the carrier plate, through gearing, and having cam forms on the face actuates the valve mechanism to cause the inlet and exhaust gases to flow to and from the cylinders as required for operation of the running cycle.
