摘要： A radial piston-type hydraulic motor has a rotatable inner body element journaled in a fixed housing having a plurality of rollers disposed at equiangular intervals about the axes of the inner body element and axially parallel thereto. The inner body element has a plurality of radially extending cylinders with reciprocating pistons disposed around the inner body element at equiangular intervals preferably greater than the angular intervals between the rollers. The outer end of each piston is provided with a cam engageable with the rollers to cause rotation of the inner body element in response to reciprocation of the pistons.

摘要： In a combination of two pressurized fluid motors fed in parallel by a common feed circuit, each of the pressurized fluid motors includes a casing and a cylinder block rotatable about an axis relative to a cam constrained to rotate with said casing and having a communication side perpendicular to the axis. An internal fluid distributor is constrained to rotate with the cam. It has a distribution side perpendicular to the axis and bears against the communication side. Distribution conduits open onto the distribution side and are formed in the internal fluid distributor of each motor. The casings of the two motors are constrained to rotate together.

摘要： A hydraulic transmission circuit is provided having at least two elementary hydraulic motors, each having a secondary enclosure and a main duct for fluid feed and a secondary enclosure and a main duct for fluid discharge. A fluid distributor distributes fluid from the main ducts to the elementary motors via the secondary enclosures. A control system controls the elementary motors. Valves connecting the fluid distributor to the secondary enclosures of the first motor put a secondary enclosure into communication with a main duct independent of an operating mode of any other elementary motor.

摘要： A hydraulic motor is provided having radial pistons, with a cylinder block, two main ducts, a fluid distributor, one distribution valve per cylinder, and a control system for controlling the distribution valves. The motor includes at least two elementary motors, and can operate in various different states in which, in each elementary motor, each of the cylinders is connected on the rising ramps to a second main duct and on the falling ramps to a second main duct; a first elementary motor being driving in a first state, and inactive or opposing in a second state, the control system operating the remainder of the hydraulic motor in the same way in these two states. A hydraulic circuit including said motor and a method of controlling such a motor are also provided.

摘要： A radial-piston, multiple-action hydraulic motor comprises a casing in which a rotor with an even number of rows of radially arranged pistons is rotatable, the casing having guides with profiles containing noncontrolled and controlled sections. The pistons of one half of the rows interact first with the noncontrolled sections then with the controlled sections and the pistons of the second half of the rows interact first with the controlled sections and then with the non-controlled sections of the profiles. A journal-type distributor is installed in the rotor and has at least two coaxial journals with channels for distributing working fluid and controlling the displacement volume of the hydraulic motor by turning synchronously in opposite directions relative to their axis, the distributing channels of each journal communicating hydraulically with one half of the rows of the pistons.

摘要： A hydrostatic bridge including two hydraulic motors each having two distinct operating cylinder capacities, both motors sharing an overall casing. The bridge has four main ducts of a first type (feed or exhaust) and two main ducts of a second type (exhaust or feed). The overall casing has three upstream ducts respectively connected to the first and second main ducts of the first type themselves connected to distribution ducts of the first motor, to third and fourth main ducts of the first type, themselves connected to distribution ducts of the second motor, and to first and second main ducts of the second type, themselves connected to distribution ducts of both motors. The bridge includes an anti-spin device capable of selectively reducing the flow rate in the first upstream duct and in the second upstream duct for selectively correcting spin of the first and second motors.
