摘要： A shaft extending along a longitudinal axis has fluid channels that increase and decrease pressure in chambers formed between the interior ends of curved pistons and adjacent closed ends of curved chambers within which the pistons reciprocate as the chamber pressure increases and decreases. The chambers and pistons are in separate cylinder block segments extending outward from opposing sides of the shaft. Each segment may have two sides extending along radial planes and joined by a curved outer surface. Pistons may be provided in pairs and have an interior piston end of each piston in a different cavity in different segments. Exterior ends of each piston in a pair of pistons are connected to a piston connector that extends inwardly from a housing so the housing rotates with the pistons.

摘要： A linear energy harvesting device that includes a housing and a piston that moves at least partially through the housing when it is compressed or extended from a rest position. When the piston moves, hydraulic fluid is pressurized and drives a hydraulic motor. The hydraulic motor drives an electric generator that produces electricity. Both the motor and generator are central to the device housing. Exemplary configurations are disclosed such as monotube, twin-tube, tri-tube and rotary based designs that each incorporates an integrated energy harvesting apparatus. By varying the electrical characteristics on an internal generator, the kinematic characteristics of the energy harvesting apparatus can be dynamically altered. In another mode, the apparatus can be used as an actuator to create linear movement. Applications include vehicle suspension systems (to act as the primary damper component), railcar bogie dampers, or industrial applications such as machinery dampers and wave energy harvesters, and electro-hydraulic actuators.

摘要： An engine housing has the shape of a regular dodecagonal, and includes a piston of the same shape that moves with a circular pivot movement about the axis of a main shaft. The piston is guided in parallel by three crankshafts synchronously rotating about this center of rotation. Through this pivot movement, the piston in six combustion chambers each consecutively brings about the four cycles of a spark ignition or diesel engine. The three crankshafts are in permanent engagement through gears which are attached in a fixed manner with a sun wheel, which is seated on a main shaft in a fixed manner, driving it.

摘要： The subject matter of this specification can be embodied in, among other things, a locking apparatus for a rotary actuator includes an outer housing comprising a cylindrical interior surface having a recess. A rotor is disposed within the outer housing. The rotor has an interior cavity and a port extending radially from the interior cavity to the cylindrical exterior surface. A piston is disposed for reciprocal movement within the interior cavity between a first position and a second position and includes a first portion having a first thickness, a second portion having a second thickness larger than the first thickness. A key is disposed for radially reciprocal movement within the port and includes a radially proximal end and a radially distal end. The radially proximal end contacts the first portion and the radially distal end does not extend into the recess when the piston is in the first position.

摘要： An engine configuration that places multiple pistons on one or two oscillating discs. The engine can be configured to operate as an internal combustion engine that uses diesel fuel, gasoline, or natural gas, or it can be configured as an expander to convert high pressure high temperature gas to rotary power. For any given set of choices of numbers of pistons and sizes of pistons, disks, and gears, there are disclosed dimensional constraints useful for more efficient functioning of the engine. This engine is especially suited as a driver for electrical power generation as it delivers high torque at low engine speeds, among other uses. Its compact design results in high power to weight ratios.

摘要： A combustion chamber in an opposed-piston, internal-combustion engine is disclosed in which the pistons tops are designed so that when they approach each other, they induce a tumble flow in one or two hemispherical spaces defined in the piston tops. The combustion chamber further includes injectors side mounted in the cylinder wall. In one embodiment, the tumble flows in the two hemispheres are in the same direction and in another embodiment, in opposite directions. In yet another embodiment, there is only one injector and one hemisphere in which a tumble flow is induced.

摘要： A hydraulic machine includes oscillating radial cylinders close to an external shell of a crown or star of cylinder-piston groups. The pistons of the groups are made sliding on a crank shaft with throw or on interposed concentric elements, which create an alternative movement in the oscillating radial cylinders. The oscillating cylinders are placed in contact with a spherical oscillation surface made on a body or shell of the hydraulic machine. A passage of the hydraulic liquid to and from the oscillating radial cylinder, to create feeding and discharge of the cylinder, is formed through at least a flat lateral external surface on the side of the oscillating cylinder, parallel to an oscillation plane of the cylinders, to and from a feeding channel on a lateral body or cover of the hydraulic machine. A seal ring, fitted at least with a contact surface that is resistant to abrasion on the wall of the lateral flat sliding surface, is interposed between the flat lateral surface in contact for passage of the liquid under pressure, and a thrust member is formed on the oscillating cylinders against the spherical oscillation surface outside of the cylinders themselves.
