Description

Rotary piston internal combustion engine with abutment slides The subject of the invention is a rotary piston internal combustion engine with abutment slides that are spring-loaded be pressed against the peripheral surfaces of the rotating body with wing lugs.

Rotary piston machines rotating in the center with arranged in the housing Abutment slides are well known, as is the arrangement of the inlet and outlet openings next to one of these sliders. In the known machines with two wing-like Approaches to the rotating body also have a work cycle every half turn, the compression and ignition of the gas mixture partly outside the rotation space, on the other hand takes place within the rotating body in special chambers. By the location of the compression chambers can therefore have a direct effect of the inflamed Gases on the rotary lobe do not take place, as this only occurs after the ignition Channels or slots must be routed in order to act on part of the rotary piston to be able to.

By the internal combustion engine according to the invention, which differs from the well-known rotary piston machines through the arrangement of two associated slides, between which the combustion chamber is formed; differs, becomes an immediate Effect of the ignited gases on the rotating body achieved.

This direct effect of the gases on the rotating body is made possible by the special The design of the pair of sliders and the slider control edges of the sash enables so that the ignition chamber that is formed opens and closes without valves. At the same time, there will be room for expansion enlarged compared to the inlet space and the amount of residual gas is reduced to a minimum by the pair of slides.

How it works: The body rotating inside this motor a (Fig. I) has protruding parts arranged symmetrically to one another at the top and at the bottom a1 and a2 (Fig. 7, 8 and 9), which have the task of controlling the sliders b, c and d (Fig. I) control.

The slide b (Fig. Io, i i and 12) has at the places where the leading edges of the rotating body protrude, each a loose, spring-loaded part b1, so that the spaces next to the slide are tightly sealed in every position of the rotating body (Fig. i and 4).

The slide c (Fig. 13 and 14) and d (Fig. 15 and 16) consist of two independently sprung parts c and cl or d and dl, so that with a certain position of the rotating body either the spaces next to the slide are separated (Fig. I and 17, section A-B) or a gap is released for the gas to pass through will (abbot). 3, section C-D and Fig. 5, section E-F).

So while the slide b (Fig. I) in every position the spaces next to separates the slide, c only seals a1 and d only seals a2.

The wing a, which moves in the direction of the arrow i, sucks automatically the gas from the inlet opening e (Fig. i and 6).

In Fig. I the rotating body has turned 180 degrees. That through e sucked in gas is precompressed here up to the point in time since a2 of the rotating body Pushes slide c outwards (Fig.4) in order to allow gas to pass through (Fig.5, section E-F) into the actual combustion chamber f (Fig. 2).

Figure 6 shows the shape of the combustion chamber f and the position of the slides as well as the rotating body, in which the combustion takes place through spark plug g. The exploding and expanding mixture (Fig.6) pushes the rotating body in the direction of the arrow, where the slide d is held up by a1 up to the position Fig. z and the Gas is able to expand (Fig.3, section C-D).

The slide d, which slides down on a2 by spring force as it rotates further, pushes the expanding gases into the expansion space except for the small remainder h (Fig. 4), in which the expansion continues. Meanwhile there is gas again in room i (Fig.4) precompressed, and fresh gas is sucked in again. The expanded gases enter in the position of the rotating body (Fig. 6) through k, for which there is no valve, as in the case of letting in is required. In every vertical position of the rotating body (Fig. 6) takes place so one work cycle takes place, so that with a rotating body two per revolution Work cycles come. With a corresponding number of axially adjacent rotating bodies, which are offset against each other in their own rotation room a large number of work cycles per revolution can be created.

Figure 6 shows the proportions of the inlet and expansion space and it can be seen that the expansion space is kept larger than the Inlet space.

Claims (3)

PATENT CLAIMS: i. Rotary piston internal combustion engine with abutment slide valves and wing lugs on the centrally rotating body, characterized in that there are three abutment slides, two of which are next to each other and so on work together so that they form a combustion chamber between them. 2. Rotary piston internal combustion engine according to claim i, characterized in that the rotating body is axially adjacent to the wing lugs Control edges (a1 and a2, Fig. 1, 2 and 3) on which loose, spring-loaded parts (b1, fig. io, i i and 12, cl, fig. 13 and 14, and dl, alb. 15 and 16) the abutment slide slide. 3. Rotary piston internal combustion engine according to claim 2, characterized in that the control edges (a1 and a2) are shaped so that, in cooperation with the abutment slide, pushing the compressed mixture through a gap between the wing attachment of the rotating body and the abutment slide (c) in the combustion chamber between the two slides, and that after ignition, the slide (d) is held up and, towards the end of the expansion, pushes the combustion gases into the expansion chamber with the exception of a small residue.
