Abstract:
The invention relates to a rotary internal combustion engine containing rotors (6, 7) comprising circular tracks and at least one fixed central disk (1,2,3), where radial valve elements move (9,10) with an axial movement as they follow the profile of the circular tracks, said circular tracks having a cam profile (37) and being designed such that the admission-compression is carried out on the side of one of the rotors (6) and the combustion-exhaust on the side of the other (7), the compressed air transfer being performed via the radial valve elements (9,10). In an alternative embodiment, it can act as a compressor.

Abstract:
A casing (1) with a circular cylindrical internal surface (3) delimits an operating chamber. A rotor (4) orbits about a chamber axis which is the axis of the internal surface (3). The rotor (4) has a circular cylindrical external surface (11), a generatrix of which is adjacent to the internal surface (3), a diametrically opposite genetrix being spaced from the internal surface (3). A vane member (17), mounted on the casing (1) and pivotable about a pivot axis parallel to the chamber axis, is accommodated in a fluid inlet/outlet aperture (18) in the casing, the vane member having a passageway (17a) communicating between the exterior of the casing and the operating chamber. The vane member (17) has an arcuate face (17b) coaxial with the pivot axis, end faces (17b) towards the pivot axis, end faces (17c) extending from the respective lateral ends of the arcuate face (17b) towards the pivot axis, and a tip face (17g) adjacent the rotor (4), these faces (17b, 17c, 17g) being sealing faces with respect to corresponding surfaces of the aperture (18) and the rotor (4). A linkage (28) connects the vane member (17) to the rotor (4) so as to keep the tip face (17g) in sealing contact with the external surface (11) of the rotor, the linkage being connected to the vane member by an articulation having an articulation axis (30) such that a plane containing the articulation axis (30) and the axis of the external surface (11) passes through the region of sealing contact.
Abstract:
A multi-stage expansion device having bypass capabilities and a variable speed drive is disclosed. In one example, the multi-stage expansion device has a housing within which a first stage, a second stage, and a third stage are housed. The housing may also be configured with internal working fluid passageways to direct a working fluid from the first stage to the second stage and/or from the second stage to the third stage. Each of the stages may include a pair of non-contacting rotors that are mechanically connected to each other and to a power output device such that energy extracted from the working fluid is converted to mechanical work at the output device. In one example, a bypass line is provided to bypass working fluid around the first stage and a bypass line is provided to bypass working fluid around the second stage.
