摘要： A vortex expander, comprising: a housing (10); and an expansion mechanism provided in the housing (10) and used for expanding high pressure fluid having an intake pressure into low pressure fluid having an exhaust pressure. The expansion mechanism comprises a fixed scroll (22) and an orbiting scroll (24) and defines an exhaust cavity (26), an air inlet cavity and a series of closed expansion cavities. A back pressure cavity (C) is provided in the expansion mechanism; the back pressure cavity (C) is in fluid communication with a medium pressure cavity in the series of expansion cavities, and is provided with at least one passage (L) in fluid communication from the back pressure cavity (C) to a low pressure region (A1) having an exhaust pressure; the passage (L) is configured such that: the passage (L) is opened when the pressure in the back pressure cavity (C) is lower than the pressure of the low pressure region (A1), and the passage (L) is closed when the pressure in the back pressure cavity (C) is higher than or equal to the pressure of the low pressure region (A1). The vortex expander can avoid the problem of being unable to be started and to operate normally; moreover, the vortex expander is simple in structure, easy to process and manufacture, and high in cost effectiveness.

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： The invention includes a" floating scroll" mechanism for scroll type fluid displacement apparatus (10). The dual orbiting scroll (60) has spiral vanes (62, 62') on both sides of the end plate (61, 61'). In a floating scroll, the orbiting scroll is dynamically well balanced, axially and radially. The scrolls are fully or semi- axially and radially compliant for maintaining minimum contacting forces between components, hence achieving good sealing for high speed, high efficiency, low friction wear and power loss. A crank shaft-sliding knuckle (64, 64') and/or peripheral crank handles-sliding knuckle mechanism (168a, 168'a) provide the dual orbiting scroll with radial compliant capability. A synchronizer (170) is used to synchronize the orientation of the crank handles (162a, 162b, 162c) to avoid the mechanism from jamming during operation and start up.

摘要： The invention relates to a rotary engine comprising a circular stator (10), a circular rotor (12) rotating about the stator, the rotor and the stator being separated by a circular cylinder (14), and at least one element with two flanges (24, 26). The rotor includes two compression pistons (16, 18) attached onto the inner surface of the rotor, said two pistons being located at both ends of a first diameter of the rotor and kept substantially in contact with the outer surface of the stator. The stator includes a recess (42, 44) at each end of a diameter, each recess forming a compression chamber with the compression piston inserted into the end of the recess in the direction of rotation of the rotor and one of the flanges of the element with two flanges, referred to as the cylinder head flange (34), the motive force being applied to the compression piston when the pressure of the gases inside the compression chamber is suddenly increased to a predetermined value.

摘要： An air turbine motor (1) has a turbine wheel (3) mounted for rotation in a housing (2). A first set of elements (8) distributed around the circumference of the turbine wheel (3) drive the wheel (3) in rotation in response to an axial flow of drive air. A second set of elements (9, 10) on a face (11) of the wheel (3) drive the wheel (3) in rotation in response to radial flow of drive air. Stators (4, 5) direct drive air to the first elements (8) in an axial direction and to the second elements (9, 10) in a radial direction.

摘要： A work unit, such as a blower, compressor, supercharger or engine is shown with a main shaft (1) and a pair of pistons (3) mounted on respective shafts (4). The main shaft (1) and the shafts (4) are connected by suitable gearing to hold the pistons (3) in a stationary orientation relative to the axis of the main shaft (1) and the housing (5). The main shaft (1) has a pair of opposed part cylindrical recesses (55) to accommodate the respective pistons (3). The arcuate surfaces (R4) of the pistons (3) cooperate with the concentric arcuate surface (R5) of the shaft (1). As the shaft (1) rotates, the edges or tips (48) of the pistons (3) can cooperate with the respective top and bottom arcuate surfaces (R1, R2) of the inner surface (49) of the housing (5) on either side of the blades (53, 54), while the external arcuate surfaces (R4) of the piston (3) can cooperate with the concentric arcuate surfaces (R3) of the internal surface (49) of the housing (5).
