摘要： A vane for a vane cell device comprising a stator and a rotor rotatably arranged in the stator with a plurality of guide grooves in each of which a vane can be movably mounted along a direction of movement. The vane has a high-pressure side, and a low-pressure side facing the high-pressure side, for fluid conveyed or flowing through a workspace of the vane cell device. The vane has a first side wall formed on the high-pressure side and a second side wall formed on the low-pressure side, wherein the first and second side wall are connected to each other by a plurality of ribs forming lateral limits of fluid channels. The first and second side wall are offset relative to each other so that the high-pressure side is only partially covered by the first side wall, and the low-pressure side is only partially covered by the second side wall.

摘要： A hydraulic pump or motor includes a body having a chamber and a rotor rotatably mounted within the chamber. The chamber and rotor are shaped to define one or more rise regions, fall regions, major dwell regions and minor dwell regions between walls of the chamber and the rotor. The rotor has a plurality of slots and vanes located in each slot. Each vane is movable between a retracted position and an extended position. In the retracted position, the vanes are unable to work the hydraulic fluid introduced into the chamber whereas they are able to work the hydraulic fluid introduced into the chamber in the extended position. A vane retaining member that is selectively actuable enables the vanes to be retained in the retracted position.

摘要： An engine comprises a compression portion and a combustion portion. The compression portion comprises twin-screw rotors, male engaged with female. The combustion portion comprises twin-screw rotors, male engaged with female. The male compression rotor and the male combustion rotor share a same longitudinal axis, and the female compression rotor and the female combustion rotor share a same longitudinal axis. A combustion plate is disposed between the compression portion and the combustion portion, and prevents flow of gas from the compression portion to the combustion portion, except through a small orifice centrally located on the combustion plate. A valve is affixed to the male rotors adjacent to the combustion plate, covering the lobes of the male rotors and extending beyond the lobes of the male rotors. The valve controls the flow of gas from the compression portion to the combustion portion.

摘要： Many versions of scissor-action engines have existed. All such prior scissor-action engine designs have used rotary reciprocal movement between the rotary piston members. The present invention uses two rotary scissor-action piston members symmetrically separating the housing cylinder into two pairs of air chambers. Two pairs of air intakes and air exhausts are strategically positioned in relationship to the two air chambers. A paired gear transmission mechanism, called a “Butterfly Gear”, is linked to the rotors to control scissor action. This invention design is a “friction-free” rotary piston and momentum exchanging spring mechanism, allowing the rotary members to rotate at high speed like a turbine blade; thus resulting in higher efficiency, by reducing energy loss from air leaking and friction. Rotary scissor-action air motors can be rotated in reverse to operate as a compressor. The invention design is a system utilizing a heat exchanger container connected with two Rotary Scissor Action Motors; one as a compressor and the second as an air motor to generate energy from hot air. “The Hot Air Generator” can use concentrated sunlight or any other heating source.

摘要： A hybrid elastomer/metal on metal motor for a helical gear device includes a rotor and stator comprising a hydraulic motor that produces work when a working fluid is pumped therethrough. The improvement involves the stator being, for part of its length, a conventional or even wall stator, using an elastomer to form a seal against the moving rotor. The stator's remaining length comprises a profiled rigid surface that forms a seal directly with the moving rotor. This gives the motor the high efficiency of the elastomer sealing against the rotor, and simultaneously provides a backup of the stator' s rigid section allowing continued motor operation at reduced efficiency, if the elastomer part failed in service. The invention also includes combinations of a regular disk stack with a rubber lining, a rigid material disk stack (or unitized element) and a circular rigid sleeve which react to rotor sideloading while permitting proper rotor orbiting.
