Abstract: A trochoidal design rotary piston engine design has a rotary piston housing with a double curve inner contour and triangular type rotary pistons. Sliding bearings distribute lubricating oil from a pressure cycle into a high pressure circuit and a low pressure bypass circuit branches to the side parts and axial cooling channels of the rotary piston housing to supply the cooling oil.

Abstract: A bearing arrangement and drive transmission arrangement of a rotary piston internal combustion engine having trochoidal-shaped casing mantle raceway surfacing and having a triangular piston controlled by a synchronous drive transmission consisting of a hollow gear and a pinion, with which the teeth of the hollow gear are machined or worked out of a piston bore extending over the entire width by impact pushing/cutting and broaching. A further bore is concentrically provided in the piston bore and extends from a side remote from the synchronous drive transmission as far as to the hollow gear and of which teeth only tooth butt ends are left standing upon which a bearing sleeve of the eccentric bearing is pressed thereon. Cooling passages or channels result between the bearing sleeve and the tooth butt ends. Transfer of contact heat from the piston onto the eccentric bearing is considerably reduced by engagement of the bearing sleeve only upon the tooth butt ends.

Abstract: A lubrication system for a rotary piston internal-combustion engine of the trochoid type, including a roller or needle bearing for the rotor on the eccentric, wherein internal engine oil seals may be eliminated. A narrow annular clearance is provided between the shaft and the pinion of the synchromesh gearing, into which a dosed quantity of fresh oil may be pumped through the adjoining side part. At that side of this annular clearance which opens towards the eccentric, a splash edge is provided which is surrounded by a collector groove arranged at the eccentric. A passage in the eccentric leads from a radially outermost part of the collector groove towards the center of the rotor bearing. The pressurizing oil flowing into the annular clearance forces the oil to leave this space whereupon it is splashed off the splash edge under the action of the centrifugal force of the rotating shaft, and transferred into the collector groove from where it is passed through the bore in the eccentric into the rotor bearing.

Abstract: A triangular piston is journalled rotating in a planetary manner upon an eccentric of an eccentric shaft journalled in a housing of a rotary piston internal combustion engine of trochoidal type of construction with a fluid cooled system in the housing with a multi-arcuate casing runway surfacing of which the side walls have the eccentric shaft passing therethrough. An eccentric bearing is cooled directly by a cooling medium conveyed via a bypass of the cooling system of the housing branched off from the cooling system and the cooling medium is conveyed via hollow spaces in the eccentric shaft into a location at the eccentric journalling the triangular piston. The cooling medium is supplied and carried away via lines opening into an annular groove extending around the eccentric in a location below and radially inwardly of the eccentric bearing. A supply line is provided in the eccentric shaft for supply of cooling medium to the annular groove and this supply is continuously in connection and in communication with at least one radial bore to the annular groove in a region of the eccentricity maximum of the eccentric and in a region of the eccentricity minimum of the eccentric there is arranged at least one bore leading back from the annular groove, which latter groove opens into an axial return flow line in the eccentric shaft and that furthermore the feed and return lines are connected to the bypass of the cooling system of the housing.

Abstract: In a mixed cooling system for the piston of a rotary-piston internal combustion engine having a trochoid construction with a triangular piston and a liner surface in the form of a double arc of a circle, a fuel injector is arranged in a side-wall of the liner and its jet is directed toward the inside wall of the corresponding corner of the piston which forms the driving corner of the expansion chamber when the piston is about to reach its bottom dead point. The starting of the injection cycle is determined by a piston position in which the corner of the piston forming the driving corner of the expansion chamber intersects the straight line located in the axis of the injection jet, and the end of the injection cycle is determined by a piston position in which the driving corner of the expansion chamber has moved past the exhaust opening.

An eccentric shaft passes through the housing and a triangular rotary piston turns upon the eccentric of the eccentric shaft. Clamping rings are provided at each of two ends of the housing. The clamping rings are circular in axial plan view and have a diameter equal to the length of the long axis of the housing and have a transition in radial direction via the housing in a region of the short axis thereof; the clamping rings are connected by adjustable bolts in a region of the short axis of the housing; a disc or cup spring is arranged at one of the two clamping rings and the cup spring is pressed by tensioning of the adjustable bolts by the clamping ring against the end of the housing as well as pressing the housing against the other clamping ring. The cup spring engages against a steel ring introduced in an end of the housing.

Abstract: A rotary combustion engine includes a peripheral housing, side housing plates, a piston, and an eccentric shaft, where the triangular piston mounted on the eccentric shaft rotates between the side plates around an epitrochoidal orbit with a long and short axis inside the housing to form three working spaces, where the gas exchange is controlled by an intake port and an exhaust port. Fuel is supplied by an injection nozzle located on the short axis of the peripheral housing, and combustion is initiated by a spark plug located shortly after the injection nozzle in the housing relative to the direction of rotation of the piston. Nozzle bores in the injection nozzle are designed in such a way that, in conjunction with a multi-fuel injection system, they guarantee reliable ignition of the fuel during each cycle.

Abstract: An eccentric shaft for an internal combustion engine, especially for a rotary combustion engine, the working unit of which comprises essentially a peripheral housing, side housing plates, and a triangular piston mounted on an eccentric of an eccentric shaft, the tips of the piston moving along an epitrochoidal orbit inside the peripheral housing to form three separate working spaces, where the rotary combustion engine can have several working units. The eccentric shaft consists of several parts, which have radial teeth at their ends, by means of which these shaft parts can be connected positively to each other by the use of a tie rod. In rotary piston engines with more than one working unit, as many inner shaft parts of identical design as there are working units can be used in modular fashion to construct the eccentric shaft.
