摘要： A bearing device includes a piston arranged in a cylinder of a rotor, and a half bearing mounted on the piston to support a roller. The piston includes a recessed holding surface, and holding side surfaces on both axial sides thereof. Each holding side surface includes a ridge portion having an arc-shaped or elliptic-arc-shaped profile protruding toward a radially inner side of the piston. The half bearing includes a partially cylindrical portion, and protruding portions at a circumferential center thereof. Each protruding portion has a protruding portion end face which includes a central recessed surface, and two support recessed surfaces located on both circumferential sides thereof, that have an arc shape or an elliptic arc shape to correspond to the profile of the ridge portion, so that only the two support recessed surfaces are in contact with the ridge portion.

摘要： A radial piston device includes a housing and a pintle fixed thereto that includes an inlet and an outlet, each aligned with a pintle axis. A rotor is rotatably disposed around the pintle and includes radially oriented cylinders. A piston is axially displaceable in each cylinder and includes a head defining a spherical contact surface. A thrust ring is rotatably disposed within the housing about the rotor and is in contact with each piston, such that a rotation of the rotor rotates the thrust ring. An inner surface of the thrust ring defines a toroidal contact surface. A contact location between the spherical contact surface and the toroidal contact surface varies as the rotor rotates about the pintle. A drive shaft is engaged with the rotor, such that a rotation of the rotor rotates the drive shaft.

摘要： A multi-piston motor/pump is disclosed particularly useful for air motor applications incorporating a cylinder block having a plurality of radially extending pistons and cylinders. Each cylinder is provided with a bronze insert at the top of the cylinder having an intake and exhaust port therein. Rotary valves are mounted on an output shaft and include axial flanges having openings therein that align with the input or exhaust openings in each cylinder. As the rotary valves rotate, the openings therein sequentially align with the input/exhaust ports provided in the bronze inserts such that air or fluid entering each cylinder enters axially of the cylinder. A center mounting plate is secured to the cylinder block and separates the input ports from the exhaust ports to enable fluid flow into the input ports and exhaust from the exhaust ports while isolating each port from the adjacent port in each cylinder.

摘要： The rotary reciprocating piston engine as a rotor rotatably journaled in a housing and a plurality of pistons movable in radial direction in the rotor between outer and inner dead points. Each piston has a piston rod mounted on a transverse shaft carrying at each end a sliding element which is displaceable in radial grooves formed in the rotor on both sides of the piston. The sliding elements are each provided on the outer side thereof facing away from the piston with a pin received in a housing-fixed star-shaped endless guide groove. The guide groove extends about the axis of rotation of the rotor and controls the movement of the pistons in radial direction between the inner and outer deadpoints.

摘要： A Hybrid Piston/Rotary engine has a stationary elliptical housing with a circumscribed inner cam surface to provide thrust, and sides with bearing supports for rotation of a rotor, at least one cylinder, a shaft with apertures therein to provide rotary valves combined with intake and exhaust ports within the bearing supports. Each cylinder has two opposed pistons connecting cam followers pivoted to the rotor which reciprocate upon rotation. During the intake stroke, the pistons separate as an intake valve opens; and fuel mixture fills the cylinder and closes as pistons compress the mixture. The rotor ports become aligned with the spark plugs within the bearing supports, and ignited gasses force the pistons apart causing the cam followers to provide thrust to the rotor. The exhaust valve is opened as the pistons contract. Four strokes are completed each rotation. The valves can also be arranged to operate as a pump.

摘要： The present invention is directed to a rotary engine power transmission system for use in vehicular as well as other applications. The power system includes a rotary engine or pump, which may be pneumatic or hydraulic in configuration. The power system includes components whose purpose is to convert rotational force into pneumatic or hydraulic pressure where that same fluid pressure can be reconverted back into rotational force. This conversion can be from a source to a driven component, or from the driven component back to the same source for use, for example, in vehicular applications for use. One purpose in a vehicular specific application is to convert rotational source energy into rotational power at the vehicles wheels, for acceleration, and to reverse this process to recapture deceleration losses.
