Abstract: A rotary combustion engine with one or more working units, which include a peripheral housing, a front housing plate, a rear housing plate or central plate on the output side, an eccentric shaft, and a piston, where the eccentric shaft includes an eccentric, a front sealing part, and a rear sealing part. Lubricating oil is conveyed by an oil pump from an oil tank through the eccentric shaft to a first main bearing, to a second main bearing, and to an eccentric bearing, from which it arrives by way of a conically shaped formation on the front sealing part in a piston space, from which it is conveyed in turn by way of a bevel on the piston and a rear bevel back to the oil tank to close the oil circuit. The bevels give a clearly definable direction to the oil circulation from the front of the working unit to the rear, reduce splash losses, and increase the cooling action on the internal surfaces of the thermally stressed piston.

Abstract: A rotary combustion engine includes a peripheral housing, a front housing plate, a rear housing plate, a piston, and an eccentric shaft, where the piston rotates to form three working spaces separated from each other by the tips of the piston. Shaft seals and piston seals seal off the oil-carrying interior space of the internal combustion engine, and the piston is sealed off against the front and rear housing plates by arcuate strips, which are bounded radially on the inside by an envelope curve. The gas forming in the working space during the combustion phase is under high pressure. Some of this gas leaks around the arcuate strips and flows inward along the flat surfaces of the front and rear plates by way of ring-shaped channels in the piston, thus arriving in recessed areas inside the envelope curves, from which it is then escapes through a vent channel. The leakage gas cannot create any pressure peaks in the area of the piston seals and the shaft seals, peaks which could negatively affect the service life of these seals.

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 radiai 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.

Abstract: A radial seal of a rotary piston engine with trochoidal-shaped casing inner peripheral surfacing and multi-corner piston, with which sealing strips are arranged in radial grooves in the corners of the piston. The sealing strips under pressure of the operating chambers of the rotary piston engine engage against the casing inner peripheral surfacing and respectively against under-pressure-side groove wall configuration. The sealing strip along a radial underside thereof has a narrow, deep groove extending parallel to the sides of the sealing strip. A sheet-metal strip is installed with nominal clearance in this first meshing groove and the sheet-metal strip projects beyond the groove. A groove spring for the sealing strip is inserted or installed in the base of this groove. A further groove is arranged in the base of the groove for the sealing strip and an edge of the sheet-metal strip projecting beyond the sealing strip engages into the further groove and is supported along the base of this further groove against the pressure of the groove spring. The further groove has a groove clearance which equals the groove clearance of the groove for the sealing strip. A sheet-metal strip has a edge-side projections on a side thereof located in the groove thereof and the groove spring is supported against these projections. Alternatively, the groove spring is fastened or secured along a side of the sheet-metal strip located in the groove.

Abstract: A heat pump unit comprising a compressor and an expansion machine for respectively compressing and re-expanding a medium which circulates in a heating or cooling circuit. The power used for compressing this medium is at least partly recovered in the expansion machine and is used for driving the compressor. The compressor and the expansion machine are inner axle, intermeshing rotary piston engines which are arranged directly adjacent to one another on a common shaft. The inner side walls of the rotary engines are adjacent to each other and have cavities and thermal insulating means interposed between them and, while being interconnected, are fixedly connected on the one hand to the shaft and on the other hand with outer rotors. The shaft is rotatably journalled in eccentrics of inner rotors, which eccentrics are rigidly connected with a stationary housing.

Abstract: A rotary combustion engine with at least one working unit, which has essentially a peripheral engine housing, a side housing plate on one side, a side housing plate on the power takeoff side, a triangular piston, and an eccentric shaft. The piston is configured of several parts, which are connected to each other. The connection is accomplished by electron-beam welding under vacuum, which yields excellent results as long as certain conditions are met. The one sidewall and the power takeoff sidewall of the piston are preferably welded to a piston housing, as a result of which the casting molds can be of simpler design and simpler contours can be used, which leads to welds of higher quality and to a decrease in the costs of casting.
