  • Publication number: 20150337725
    Abstract: The essence of the solution resides in that an internal combustion engine with rocking pistons is constituted by a shared working space in a shared housing (1) of the motor and a compressor in the central portion of which there are formed in a mirrored fashion combustion chambers (2, 2.1) containing rocking blades (3, 3.1) of the motor that are rigidly radially supported on a turnable central shaft (4) and in a carrier ring (4.1) and wherein the rocking blades (3, 3.1) are to advantage mutually angled with respect to each other and wherein the combustion chambers (2, 2.1) are delimited on the one side by delimiting partitions (5, 5.1) radially disposed at the inner circumferential surface of the shared housing (1) of the motor and the compressor and separating the combustion chambers (2, 2.1) from primary compressor chambers (6, 6.1) of the primary compressor part, and on the opposite side by a pair of rocking blades (3, 3.

  • Publication number: 20110131997
    Abstract: An apparatus for acquiring mechanical energy on the basis of the gravitational effect and reduced pressure, comprising at least one double-acting hollow piston (1) accommodated in a horizontally oriented cylinder (2), the essence of which re-sides in that the double-acting hollow piston (1) is provided with centrally and mutually oppositely arranged hollow piston rods (3, 3.1) that are equipped with steam inlets (4, 4.1), wherein a free end of a first hollow piston rod (3) that is closer to a first vertical elevator carrier (6) is connected to a first weight cable (5) that is guided over a first pulley system (6.2) and a free end of an oppositely oriented second hollow piston rod (3.1) that is closer to a second vertical elevator carrier (6.1) is connected to a second weight cable (5.1) that is guided over a second pulley system (6.3), wherein a first weight (7) that is slidably supported on a first guiding rod (8) is connected to the opposite end of the cable (5) and a second weight (7.

  • Patent number: 7572118
    Abstract: A rotary machine with orbiting twin blades, especially for expansion drive units and compressors, includes a stator housing bounding an internal chamber, a rotor part received in the chamber for rotation and including at least two entraining rings axially spaced from one another and at least four entraining bars interconnecting the entraining rings and defining respective slots between themselves. A carrier shaft is mounted in the internal chamber for rotation and carries for joint rotation therewith at least two pairs of eccentric members. At least two twin blades are each supported on one of the pairs of eccentric members for relative turning therebetween and each includes two blade portions passing through oppositely located associated ones of the slots into close proximity of the inner peripheral surface of the stator housing.

  • Publication number: 20080120975
    Abstract: A Stirling thermodynamic cycle rotary thermal machine includes an eccentric shaft rotatably supported in a stator housing, a plurality of double piston carriers each carrying a plurality of pairs of oppositely arranged pistons, and a rotor having a number of cylinders each accommodating one of the pistons. Hot and cold corridors, separated from one another by a thermally separating wall, are defined around the rotor. Some of the cylinders in the rotor are associated with the hot corridor and the remaining ones with the cold corridor in a heat-exchange relationship therewith. Conduits with regenerators interposed in them connect the hot and cold corridor pistons with one another such that the respective hot corridor cylinder is ahead of the associated cold corridor cylinder by 90° as considered in the direction of rotation of the rotor.

  • Patent number: 6368089
    Abstract: An orbiting blade rotary machine, especially for use in compressor and expansion motor units, includes a stator housing bounding an internal space that includes a substantially cylindrical internal chamber centered on a central axis. A power shaft extends in a centered relationship along the central axis through the internal space, being mounted on the stator housing for rotation about the central axis. Each of a plurality of orbiting blades extends substantially radially outwardly from the power shaft in the internal chamber toward the stator housing in its neutral position, being supported on the power shaft for pivoting within a limited angular range around the neutral position. An eccentric rotor is mounted in the stator housing for rotation about an eccentric axis parallel to and transversely offset from the central axis, being accommodated in the internal chamber to delimit a working space that the orbiting blades subdivide into individual compartments.
