Working method and device of a vane piston internal combustion engine

Priority: Luxembourg
Patent application dated June 26, 1964

The development in the field of conventional internal combustion engines, in particular that of piston engines, seems to be approaching its climax. One can assume that in principle with regard to the efficiency and the Reduction of the power-to-weight ratio, no greater successes are to be expected.

909842/03 * 7

In order to reduce the existing efficiencies and, above all, the power-to-weight ratio significantly, a working method is used proposed a vane piston internal combustion engine in which a number of profiled vane pistons in more appropriate Way, individually and independently of each other, radially on an eccentric one axially mounted in the center of a rotor Eccentric shaft is rotatably arranged and the eccentric shaft has as many eccentrics as there are vane pistons. The invention relates to a method and an apparatus in which a number of appropriately profiled Vane pistons, which extend axially on both sides in the same plane within a centrically rotating rotor are, independently of one another, individually by means of appropriate offset eccentrics of an eccentric shaft, which is axially mounted centrally in the rotor, inevitably be controlled radially in an elliptical orbit, whereby between the vane piston working surfaces, the inner elliptical housing track of the housing, the radial rotor face and the inner housing walls that are axial on both sides the housing parts continuously migrating suction, compression, working and expansion spaces are formed and the vane piston faces inevitably control the inlet and outlet channels for gas exchange, with the eccentric shaft in opposite direction of rotation of the rotor and the vane piston rotates at the same speed.

To illustrate the invention, the following description of an exemplary embodiment should be based on the drawings to serve. In the drawings is

Figure 1 is an end view of the internal combustion engine, partially on average;

Figure 2 is an axial longitudinal view of the internal combustion engine in Figure 1, partially in section.

The eccentrics 7, 8, 9 and 10 are individually axially adjacent to one another and radially at equal distances from one another on their crank circle, appropriately offset on the eccentric shaft 11 arranged so that the vane pistons 3, 4, 5 and 6 on the one hand free the eccentrics of the eccentric shaft within the rotor 1 and on the other hand individually by means of circular segment-shaped bearing shells or slotted pendulum bolts 2 at equal distances from one another in the circular arc-shaped bearing sections 47 of the rotor circular ring sections 58 of the rotor are coupled with this inevitably and movably, so that the circular segment-shaped bearing shells or pendulum bolts with the vane pistons stored therein perform a free pendulum movement and the vane pistons perform a radial sliding movement in them can.

Due to the above-mentioned arrangement of the vane pistons between the rotor and the eccentric shaft and the opposite direction of rotation of the rotor to the eccentric shaft at the same speed, the radial vane piston faces inevitably run through an elliptical circular path with a major axis AB and a minor axis cd without any constriction - the center of which is also the center of the rotor axis and the eccentric shaft is. At the end points of the small elliptical axis cd the vane pistons run flush with the outer face diameter of the rotor / while at the end points of the large elliptical axis AB the vane pistons have their greatest projection from the rotor, which corresponds to the respective eccentric stroke of the eccentric shaft. This' elliptical circular vane piston path is expediently assigned a housing 55 with a parallel inner elliptical housing track 18, the vane piston end faces being almost brought up to this and sealing strips 13 which act radially outwardly are arranged in the end faces of the vane pistons. As the rotor rotates, the required working spaces are now alternately and inevitably formed between two vane pistons, the rotor face and the inner housing track, or the suction chamber 17, the compression chamber and the combustion chamber 14 and ^r ^> the expansion chamber 16, at the same time the Vane piston end face

torque generated on their surfaces by the combustion pressure directly transferred to the rotor and its axis as usable work.

Furthermore, the rotor cheeks of the rotor on both sides are axially perpendicular or conical to the outer diameter Associated with the rotor axis extending circular ring surfaces 66, on each of which a non-rotating piston ring-like sealing element 28, 29 with the same outer diameter of the rotor on the one hand is pressed by means of spring elements 26 and on the other hand axially movable with its radial clamping force in the cylindrical fitting bores 64 of the housing and the housing cover is stored. Furthermore, the rotor and the rotor axis run axially on both sides partially directly in the coolant, with the Rotation surfaces cause the cooling circuit.

The working method and embodiment will be explained for example on an internal combustion engine operating with four vane pistons. If the one shown in Figure 1 Rotor 1 rotated by 45 ° in the direction of the arrow, for example, the projection of the vane piston 3 from the rotor 1 is due to the Inevitable control caused by the eccentric 7 of the eccentric shaft 11 and also the eccentric 7 is 45 ^

of the eccentric 7 lies on the largest axis AB. Here has the eccentric 7 reaches its final stroke and the wing piston 3 reaches its maximum projection.

If the rotor 1 is now rotated by a further 90, the vane piston 3 is inevitably withdrawn by the eccentric 7 until the radial longitudinal axis of the vane piston 3 coincides with the minor axis cd of the elliptical circular path 18, so that the end face of the vane piston 3 is flush with the end face of the rotor 1, close to the elliptical housing track 18 is at the end point of the minor axis cd. This cycle inevitably repeats itself for all four in rotor 1 arranged wing pistons 3, 4, 5 and 6 and their eccentrics 7, 8, 9 and 10.

In the combustion chamber 14 (Figure 1), between the two vane pistons 3 and 4, the end face of the rotor 1, its recess 23 and is formed by the inner elliptical housing track 18, is the final compression of the ignitable mixture reaches and is ignited at that moment, while, £ J

Gases are expelled from the wing piston 3 into the exhaust duct 20. In the intake chamber 17, the intake stroke is ended, with the Vane piston 5 overflows the intake channel 19 and the compression is initiated. As a result of the persistence, the rotor 1 continues to run. Here becomes from the ignition point on the piston surface of the vane piston 3, on which the combustion pressure acts / increasingly larger, while the piston area of the vane piston 4 becomes smaller and

and at the end point of the minor axis cd is zero, the The work-performing piston surface of the vane piston 3, on the other hand, is at the same moment on the end point of the major axis AB on biggest. The wing piston 3 does work until the Piston areas of the wing pistons 3 and 4 are the same size have, at the same moment the exhaust channel 20 is exposed by the wing piston 3 and the burned gases are pushed by the wing piston 4 via the outlet channel 20 into the open. It follows from this that with one revolution of the rotor 1 with the four wing pistons 3, 4, 5 and 6 inevitably four intake cycles, four compression cycles, four work cycles and perform four exhaust strokes.

In FIG. 2, the rotor 1 is shown with its hollow axis 45 and the one axially supported therein by means of the ball bearings 41 and 42 The eccentric shaft 11 is shown with the eccentrics 7, 8, 9 and 10, the vane piston 3 being rotatably arranged on the eccentric 7 and the remaining wing pistons 4, 5 and 6 are mounted with a hinge-like offset suspension (not shown here) on their Eccentrics 8, 9 and 10, which are offset from one another by 90, arranged, the wing pistons 3, 4, 5 and 6 also with 90 spaced from each other in the rotor circular ring sections 58 of the rotor 1 are mounted.
