Abstract: A structure for reducing a refrigerant flow loss in a compressor includes a refrigerant flow resistance reducing unit to reduce a refrigerant channel resistance at a lower surface of a rotor facing a compression mechanism unit. When the high temperature and high pressure refrigerant gas discharged from the compression mechanism unit flows to the discharge pipe through the refrigerant passage including the gap between the rotor and the stator of the electric mechanism unit, the flow resistance of the refrigerant gas is reduced. Therefore, since the refrigerant can flow smoothly, a flow loss of the refrigerant can be reduced and, as a noise generation is reduced, a reliability can be heightened.

Abstract: A drive rod has pins on each end of its body. Each pin has tapered threading and little or no undercut thereby enhancing its ability to transfer rotational motion through the drive rod string by increasing the surface area through which torque is transferred. The tapering of the threading on the pins allows for connectors having thicker walls. This means the connectors can withstand higher rotational stress. The drive rods and connectors are especially well suited for use with progressive pumps.

Abstract: A vane supporting apparatus for a hermetic compressor supports vanes contacting to both cam faces of a dividing plate using torsion bars having square or circular cross sections, and thereby a height of the supporting apparatus supporting the respective vanes is lowered to reduce a distance between a motor device unit and a compression device unit, and accordingly, a length of the compressor in shaft direction is reduced to realize miniaturization of the compressor.

Abstract: A toroidal engine is provided having opposed rotor assemblies supporting pistons arranged on each rotor assembly. Part toroidal working chambers are formed between the pistons in which a combustible mixture of air and fuel is compressed and then ignited at minimum working chamber volume forcing the then active pistons and rotor assemblies to accelerate. The rotor assemblies drive a planetary member for rotation about its axis through a sliding pin connection. The or each planetary member is supported on a crankpin of a crankshaft and is integral with a planet gear meshed with a sun/annulus gear centered on the crankshaft axis. The crankshaft may be arranged to counter-rotate relative to the rotor assemblies by meshing the planetary member gear with an annulus gear or in the same direction by meshing with a sun gear.

Abstract: An oscillating-piston engine comprises a housing, in which several pistons configured as two-armed levers are arranged pivotably, respectively, around a pivot axis being parallel to a central housing axis and movable commonly in a revolution direction. The pistons comprise running surfaces on their side facing away from the housing inner wall, which are guided alongside at least one control cam when the pistons revolve in the housing, of a centrally housing-fixed cam piece, in order to control the pivot movements of the pistons in revolution. The control cam is configured as inner contour on the cam piece, alongside of which the pistons are guided supported to the side of the centrifugal force via the running surfaces. The cam piece comprises another, inner contour configured as a control cam alongside of which the pistons are guided supported to the direction of the central housing axis via the running surfaces.

Abstract: Apertures through each face of a planetary rotor, volutes for low loss delivery and collection of fluid to and from the working volumes of a planetary rotary pump, compressor, or turbine, and zero clearance seals by using continuous carbon fiber reinforced polyetheretherketone (PEEK) or other self-lubricating materials significantly improve the volumetric flow rate of such rotary pumps compressors or turbines. By establishing a means to vent each working volume to an intake or exhaust port at arbitrary rotor positions, apertures linking working volumes to intake or exhaust ports allows each working volume of a multilobe planetary rotary pump to function independently near peak volumetric efficiency. An additional means to improve the performance of planetary rotary pumps has been established by using scroll-like volutes which collect and deliver the exhaust and intake flow for each working volume in a manner which reduces the fluid dynamic loss associated with conventional sudden expansions and contractions found at the inlet and exit of a plenum. To minimize leakage between the separate working volumes and improve performance, self lubricated continuous carbon fiber reinforced polyetheretherketone seals are employed for components in high speed sliding contact. The continuous carbon fiber reinforced PEEK can withstand high sliding speeds, high temperatures with low wear and excellent foreign object impact resistance.
