A rotary machine with a deformable rhomb, includes a housing defining a stator for receiving a rotor which is a deformable rhomb in contact, with or without clearance, with the internal surface of the housing, the deformable rhomb including a plurality of pistons, preferably four pistons, connected one after the other by a pivotal hinge having an axis parallel to the longitudinal axis of the housing and thus defining a closed chain; the internal surface of the housing of the machine defining at least one cavity so-called external cavity, with the exterior of the deformable rhomb, and with the lateral closure walls of the housing, and at least one cavity so-called inner cavity being formed in the interior of the rotor with the lateral closure walls of the housing; at least one of the external cavities and/or at least one of the inner cavities being connected, directly or indirectly, to the inlet of at least one fluid circuit external to the machine, wherein the external cavities and inner cavities include together at least three variable-volume cavities capable of fulfilling at least three different functions simultaneously or at least three identical functions successively or at least three functions, at least one of which is different from the other two and is realized simultaneously with the other two functions which are identical and realized successively, each of the functions being selected from those of: combustion engine, turbine, compressor, pump, measuring device, mixer, flow distributor, energy converter, grinder, so as to modify at least one of the parameters of the fluid exiting the machine relative to the incoming fluid.
A rotary machine with a deformable rhomb, comprising a housing (1) defining a stator (2) for receiving a rotor (3) which is a deformable rhomb (4) in contact, with or without clearance, with the internal surface of the housing (1), the said deformable rhomb (4) including a plurality of pistons (6), preferably four pistons, connected one after the other by a pivotal hinge (7) having an axis parallel to the longitudinal axis of the housing (1) and thus defining a closed chain;
The machine according to one of the preceding claims, characterized in that it comprises means for the transfer of fluid from one variable-volume cavity to another.
The machine according to one of the preceding claims, characterized in that an inner cavity (10) is realized so as to have at least one surface in common with the intrados face (11) of at least one of the pistons (6) and/or with the intrados of at least one of the pivotal hinges (7) and/or with at least one intermediate piece connected to one of the pistons (6) or to one of the pivotal hinges (7).
The machine according to one of the preceding claims, characterized in that the said inner cavity (10) is an intrados circular cavity (18) formed by the space comprised between the intrados faces (11) of two connected pistons (6), a circular cylinder (19) internal to the deformable rhomb (4) and the lateral closure flanges (12, 13).
The machine according to one of the preceding claims, characterized in that the said inner cavity is an off-center external toric cavity (31) defined by the space comprised between the external surface of a sliding toric device, the ends of which rest on two connected pistons (6), the connected pistons (6), the pivotal hinge (7) and the lateral closure flanges (12, 13).
The machine according to one of the preceding claims, characterized in that the said inner cavity is an off-center inner toric cavity (32) defined by the space comprised between the piston of a first toric device (33) and the cylinder of a second complementary toric device (33), the piston resting on one of the pistons (6) and the cylinder on another piston (6) adjacent to the first, and the lateral closure flanges (12, 13).
The machine according to one of the preceding claims, characterized in that the said inner cavity is a off-center central toric cavity (34) defined by the space comprised between the central axis of the rhomb (4), the external surface of a toric device the ends of which rest on two median arms of the rhomb (4) and the lateral closure flanges (12, 13).
The machine according to one of the preceding claims, characterized in that the said inner cavity is a helicoidal cavity defined by the space comprised between the complementary parts of a helicoidal connection, the relative movements of which are imposed by the transmission device or by the rhomb (4).
The machine according to any one of the preceding claims, characterized in that at least two of the said external peripheral cavities (8) or at least two of the said inner cavities (10), or at least two of the external (8) and inner (10) cavities transport a different fluid.
The machine according to one of the preceding claims, characterized in that it comprises zones for the exchange of fluid with the external cavities (8), these zones being ducts formed in the pistons (6), the pivots (7), the flanges (12, 13), the profile of the housing (1), or the transmission device.
The machine according to one of the preceding claims, characterized in that it comprises zones for the exchange of fluid with the inner cavities (10), these zones being ducts formed in the pistons (6), the pivots (7), the flanges (12, 13) or the central shaft (57), or more generally the transmission device of the machine.
The machine according to one of the preceding claims, characterized in that the pistons (6), the inner surface of the housing (1), the arms of the diagonals (41, 42) or the arms of the medians (30) are provided with blades so that the variations of the dynamic parameters of the fluid predominate over the variations of the static parameters.
The machine according to one of the preceding claims, characterized in that its operation can be reversible.
