Abstract: Previous compressors have employed compressors to compress and circulate refrigerant through a circuit, and have been unable to combine the differing advantages of rotary compressors, scroll compressors and screw compressors. The present invention combines these advantages, as well as inhibiting refrigerant leakage and improving overall performance, by particularly fixing the position of the compression member of the compression element relative to the driving element. The driving element is stored in a sealed container of the compressor. The compression element includes a cylinder having suction and discharge ports and a compression member which compresses a fluid (refrigerant) sucked from the suction port to discharge the fluid via the discharge port; and a vane partitioning the compression space in the cylinder into a low pressure chamber and a high pressure chamber.

Abstract: A compressor having a compression element with a cylinder in which a compression space is constituted, a suction port and a discharge port which communicate with the compression space in the cylinder, a support member which closes an opening on the cylinder and a rotary shaft which is rotatably supported by a main bearing as a bearing formed on the support member. A compression member, whose one surface crosses an axial direction of the rotary shaft is inclined continuously between a top dead center and a bottom dead center and is disposed in the cylinder to be rotated by the rotary shaft, compresses a fluid sucked from the suction port to discharge the fluid via the discharge port. A vane which is disposed between the suction port and the discharge port to abut on one surface of the compression member partitions the compression space in the cylinder into a low pressure chamber and high pressure chamber.

Abstract: The invention can be used as a high pressure rotor vane pump or hydro motor. Rotor vane machine comprises a rotor including working and supporting parts connected via force chambers of variable length so that they rotate synchronously with a possibility of little reciprocal axial movements and tilts required to provide sliding insulating contact of face surfaces of the working and supporting pans of the rotor with the surfaces of the working and supporting cover plates of the housing correspondingly. Between the supporting cover plate of the housing and supporting part of the rotor there are made supporting cavities hydraulically connected via the means of local pressures balancing to the force chambers of variable length and cavities of the working chamber in the annular groove of the working part of the rotor. The losses on friction and cavitation decrease and the reliability increases.

Abstract: The present invention may be used in pumps and hydraulic engines and increases the functional capacities of rotary machines. This invention relates to a rotary machine comprising a body in which an adjustment member is mounted so as to be capable of displacement along the rotation axis. A plurality of systems, that define the axial and mutual disposition of sliders, are mounted so as to be capable of changing their position relative to the rotor and the body, and are cinematically connected to the adjustment member. The sliders are mounted so as to be capable of changing their position upon displacement of the adjustment member.

Abstract: A steam engine of the rotary type including a housing with two annular chambers with each chamber having a piston assembly operable therein. The piston assemblies are carried by a common shaft and displaced 90 degrees apart. Each piston assembly includes two pistons. The pistons have their working end surfaces 180 degrees of rotation apart. The rotor shaft is hollow along a portion of its length. The hollow portion of the shaft delivers fluid under pressure from an external source through channels within the pistons to fluid troughs in the circumferential surfaces of the annular chambers. Additional channels in the annular chambers and housing provide fluid under pressure to actuate shuttle valves at specific rotation locations of the pistons in each chamber. Each chamber includes side wall vents for exhausting spent working fluid. A screen is positioned vertically between the adjacent vents to cause condensate to be directed to a collection sump by gravity.

The recesses are made in movable elements of the stator such that the depth of the recesses can be made variable thus providing a device of variable capacity. The device is applicable to brakes and dampeners, as well as to engines and pumps.

Abstract: A rotary machine which can function as a pump or compressor or a motor, having a stator having a cylindrical working chamber within which is housed a rotor. The rotor is a disk having a major side flat surface and peripheral surfaces in contact with inner surfaces of the housing defining the working chamber. A partition divides the working chamber in two working spaces on a major side of the disk opposite to the flat side thereof. The resliently biased partition makes sliding contact with two symmetrically disposed surfaces of the opposite side. These symmetrical surfaces merge smoothly with an eccentric flat surface and define two symmetrical portions of the disk radially of the eccentric flat surface which have a thickness progressively decreasing axially and in a radial direction away from the eccentric flat surface, i.e., in a direction toward the periphery of the disk.

Abstract: An apparatus for chemically processing an item by submersion in a liquid bath having a means for rotating the item while it is submerged. The means for rotating the item includes a positive displacement continuous-rotation motor capable of submersion in the liquid bath jointly with the item being processed. Operation of the continuous-rotation motor is energized by a flow of pressurized fluid which also serves to exclude the processing liquid chemical from the interior of the motor.

Abstract: The Toroid Sweep Engine with Reciprocating Jut generates power within a toroidal-shaped chamber whose walls are divided into two ring-like sections which are free to rotate relative to one another around the toroid axis. An obstacle juts from each of the wall sections into the chamber. Fresh air is pumped at high pressure and high temperature into a region of the chamber between the two obstacles, and fuel is then injected into and burned in this region. The products of combustion force the obstacles apart, turning a wall section, and when the obstacles eventually meet after circumnavigation of the toroid, one of them withdraws from the chamber allowing the obstacles to pass. More fresh air and fuel are introduced between the again separating obstacles following the rendezvous, while spent gases from the previous burning are swept and squeezed out an exhaust duct leading from that volume within the chamber which is compressed between the obstacles.

Abstract: A vane pump has a cam member carried upon a drive shaft in coaxial relationship therewith. The axial sides of the cam member define annular cam surfaces which each engage an array of vanes disposed in a fixedly mounted stator. An interior portion of the drive shaft is hollowed to provide a fluid inlet to passages in the cam member which communicate with the cam surfaces. The cam member is provided with additional passages to receive discharge flow from intervane volumes and direct such flow to the radially outer periphery of the cam member.

Abstract: A reversible fluid device (motor/pump) of the sliding vane type, in which the vanes slide in radial slots formed through the cylindrical periphery of a rotor from side to side in a direction parallel to the axis of rotation of the rotor. Sliding of the vanes is effected by opposed complementary cam surfaces at either end of a cylindrical chamber within which the rotor rotates. The periphery of the rotor and a top edge of each vane, are maintained in constant sliding contact with the cylindrical chamber wall. Opposed edges of the vanes are in constant contact with the cam surfaces. Thus, as the rotor rotates, the vanes, rotor, chamber and cam surfaces define varying volume pressure cells. Selective pressurization of these cells via fluid conductors rotates the rotor (motor operation); rotation of the rotor selectively pressurizes the conductors (pump operation).

Abstract: The invention relates to positive-displacement fluid machines which may be used as pumps, compressors or motors.The machine includes a piston integral with the stator and engaged in an annular cylinder formed in the rotor. Movable partitions slide in longitudinal grooves in the rotor and create fluid-work chambers in the cylinder. Cams for actuating the partitions determine, between the rotor and the stator, periodically-variable volumetric spaces filled with fluid under pressure suitable for providing an assisted control for the displacement of the partitions.
