摘要： A rotary fluid device comprises: a cylinder (21) having an annular cylinder chamber (50); an annular piston (22) which is accommodated in the cylinder chamber (50) to be eccentric relative to the cylinder (21), the annular piston (22) dividing the cylinder chamber (50) into an outer working chamber (51) and an inner working chamber (52); and a blade (23) placed in the cylinder chamber (50) and partitioning each of the working chambers (51, 52) into a high-pressure space and a low-pressure space. The cylinder (21) and the piston (22) relatively rotate. The outer working chamber (51) constitutes a compression chamber which compresses and discharges a sucked fluid with the progress of the relative rotation of the cylinder (21) and the piston (22). The inner working chamber (52) constitutes an expansion chamber which expands and discharges a sucked fluid with the progress of the relative rotation of the cylinder (21) and the piston (22).

摘要： A rotary internal combustion engine comprises a chamber, a cam member (8), within said chamber, a rotor (3) surrounding said cam member and mounted for rotation with respect to said cam member about a fixed axis in the chamber, fuel and air inlet means (10) to the chamber, an ignition device (12) and exhaust outlet means (9) from the chamber angularly spaced about said axis, and a plurality of radially displaceable sealing members (5) angularly spaced with respect to said axis and each passing through said rotor radially, portions of the sealing members contacting the rotor and the chamber wall and to divide the chamber into compartments, inward portions of the sealing members contacting the rotor and the cam member forming interior compartments. The sealing members are divided into radially inner and radially outer portions and means (34) is provided urging said portions radially apart. Lubricating fluid is pumped from the interior compartments for cooling and/or filtering upon rotation of said rotor and said sealing members. The cross section of the chamber perpendicular to said axis is a continuous circular curve with two diametrically opposed arc shaped bulges each defining a space between the rotor and the chamber, and the shape of the cam member follows that of the chamber so that the radial distance between the cam surface of the cam member and the interior wall of the chamber is substantially constant, and such that the rotation of the rotor is accompanied by radial displacement of the sealing members through said rotor by the cam member to maintain contact between the sealing members and the chamber wall. A pump or compressor may be similarly constructed.

摘要： The casing (1) of a positive displacement machine has a cylindrical internal surface (3) delimiting an operating chamber which accommodates an orbiting piston (4) having a cylindrical external surface. At least one of the said surfaces, e.g. the internal surface (3), is at least partly constituted by a peripheral wall (2) having a front surface facing the operating chamber and a rear surface. The peripheral wall (2) having through-slots (22) which extend parallel to one another and accommodate respective compliant strips (24) extending from the front surface to the rear surface. The strips (22) are retained in the slots (22), against pressure in the operating chamber, by a retaining device such as a clamping member (28). An assembly of three positive displacement machines and engines comprising first and second positive displacement machines are also described.

摘要： The engine according to the invention comprises: a) a casing (12) inside which an annular cavity is formed; b) an annular rotor (14), housed within the annular cavity; c) multiple mobile chamber elements (10), secured to the rotor (14). The annular cavity has, in some regions, cross-sectional sizes substantially greater than the cross-sectional sizes of the rotor (14) so as to define multiple hollow chambers (16, 18). The mobile chamber elements (10) can be displaced, within at least part of the hollow chambers, transversally relative to the annular body of the rotor (14) while contacting the walls of the same annular cavity and separating in fluid-tight manner the hollow chamber portion in front of the mobile chamber element (10) from the hollow chamber portion behind the mobile chamber element (10).

摘要： ® In a fluid power converter, such as a hydraulic pump or motor, having a rotor and stator with vanes in both the rotor and stator, the improvement in the vane slots on one or both of the rotor and stator in which a ramp is provided on both sides of the open ends of each slot. The ramps are directed outwardly towards the annular space between the rotor and stator for allowing a crossing vane to cam out of the opposing slot thereby preventing the crossing vane from catching in the opposing slot.
