Abstract: A piston suspension for a reciprocating piston engine, especially a prime motor or pump with one or two pistons per cylinder, has for each piston at least three force transmissions, which each consist of connecting rod or thombus and of a crank, wherein the axes of the crankshafts are not congruent.

Abstract: A burner device for combustion of a combustible mixture of two flowable components consists of a chamber housing, first feed means for the first component, second feed means for the second component and an outlet opening for the combustion gases. Serving as feed means for the first component is an injector pipe, which has a rearward axial bore at its end oriented towards the outlet opening, a narrower forward axial bore at its other end, a constriction between the two bores. The feed means for the second component consists of at least one inclined channel which extends radially and obliquely relative to the injector axis with the apex of the angle .alpha.

Abstract: A rotary engine in which the expansion pressure of a working gas is converted into a mechanical rotary movement consists of an inner engine element with an outer circumferential surface and an outer engine element which surrounds the inner element and has an inner circumferential surface, the two surfaces being disposed closely adjacent and facing each other. Disposed at, for example, the inner surface are three spaced projections, which transmit the expansion pressure of the gas to the inner element, and three expansion chambers between the projections. Four reaction members, which are each movable into the expansion chambers in turn and transmit the gas expansion pressure to the outer element, are mounted at the circumferential surface of the outer element. The two circumferential surfaces have the form of complementary annular surfaces, wherein in cross-section the inner surface has the shape of a concave, parabola-like curve and the outer surface the shape of a convex, parabola-like curve.
