    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 closed cycle engine power structure and a power generation method, includes a cylinder block and an inner shell. The inner shell is located at the cylinder block, and the inner enclosed cavity of the cylinder block is divided into an outer duct and an inner duct, and an electric coil is arranged in the inner shell. An Archimedes pump is arranged in the inner duct, the electric coil is in drive connection with the Archimedes pump to form a motor structure. Tension structures are arranged in the outer duct. The Archimedes pump is driven to rotate to form a pressure difference between the top and bottom of the cylinder block, generating airflow around the tension structures. According to Bernoulli principle, the pulling force is generated by tension structures. The tension structures concentrate on the cylinder block to form the power of the engine power structure.

    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 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.
