20090120406 | ROTARY PISTON AND CYLINDER DEVICES - A rotary piston and cylinder assembly having two rotary piston and cylinder devices, each device including a rotor and a stator, the stator at least partially defining an annular cylinder space, the rotor being in the form of a ring, and the rotor having at least one piston which extends from the rotor ring into the annular cylinder space. In use the at least one piston is moved circumferentially through the annular cylinder space on rotation of the rotor relative to the stator, the rotor body being sealed relative to the stator, and the device further having cylinder space shutter means which is capable of being moved relative to the stator to a closed position in which the shutter means partitions the annular cylinder space, and to an open position in which the shutter means permits passage of the at least one piston, the cylinder space shutter means including a shutter disc, wherein the devices are connected by a transfer passage. | 05-14-2009 |
20100024764 | THERMAL ENGINE - A thermal engine that comprises a rotary element. A plurality of drive elements are arranged in the rotary element. Each drive has a plurality of piston/cylinder arranged around a common central expansion space. Piston heads of the pistons abut on a power transmission surface of the rotary element in order to drive the same. | 02-04-2010 |
20120145120 | AXIAL-PISTON ENGINE, METHOD FOR OPERATING AN AXIAL-PISTON ENGINE, AND METHOD FOR PRODUCING A HEAT EXCHANGER OF AN AXIAL-PISTON ENGINE - The aim of the invention is to improve the efficiency of an axial-piston motor. To this end, the axial-piston motor comprises at least one compressor cylinder, at least one working cylinder and at least one pressure line guiding the compressed fuel from the compressor cylinder to the working cylinder via a combustion chamber. The fuel flow from the combustion chamber to the working cylinder is controlled by at least one control piston driven by a control drive, and the control piston is subjected to a compensation force oriented against the combustion chamber pressure, on the side thereof facing away from the combustion chamber, in addition to the force applied by the control drive. | 06-14-2012 |
20140238337 | INTERNAL COMBUSTION ENGINE - The internal combustion engine includes at least one compression chamber, formed by a housing and therein compressor rotary pistons rotating on a shaft with compressor sealing strips, on which optionally movable toggle sealing strips are arranged. The compression chamber is in gas connection with at least one ignition chamber and this ignition chamber is in gas connection with at least one expansion chamber. This chamber is formed by the housing and by an expansion rotary piston rotating in this chamber on a shaft. An at least one flywheel rotating in the housing on a shaft provided for the power transfer together with the compressor rotary piston forms a compression chamber and together with the expansion rotary piston forms an expansion chamber. The ignition chamber is equipped with a device for igniting a compressed gas mixture. | 08-28-2014 |
20150007793 | Hybrid Cycle Combustion Engine and Methods - A method of operating an internal combustion engine having a housing with a recess, and a piston rotatably mounted in the housing, wherein the housing and the piston form, over the course of shaft rotation, initial, second and third volumes in differing amounts for the phases of compression, combustion and expansion, in a manner that is smooth and continuous, which method includes (a) compressing air into a chamber formed by the recess and the piston, (b) introducing fuel into the chamber of compressed air, and (c) igniting the mixture of compressed air and fuel. | 01-08-2015 |
20150300173 | IGNITION ENGINE OF THE ROTARY TYPE WITH A DOUBLE ROTATION CENTER - The present invention refers to a spark ignition engine of the rotary type with a double rotation center, comprising a stator (A) with a stator central body (A | 10-22-2015 |
