- a combustible gas mixture for example from a carburetor or injection device
- the inlets 53 to the working spaces are arranged on a common division circle, in such a manner, that the cylinder barrel 49 upon its oscillation only projects over one inlet 53 at a time (FIG. 4). Due to lthe fact, that the shaft 42, eccentric 45 and bearing 46 rotate in operation in the direction indicated by arrow, the inner sleeve 47 is caused to oscillate.
- This oscillating movement is also transferred to the cylinder barrel 49 by means of the blades 48 displaceably mounted in the body 50.
- the working spaces 54 defined between the cylinder barrel 49 and the guide body and blades 48 will continuously change the volume, and also the inner working spaces 55 defined by the inner sleeve, the inner periphery of the guide body 50 and the blades 48.
- the outer Working spaces thus, compress the gas mixture entering at 53.
- the compressed volume is the smallest in the working space 54e and 54d (FIG. 4)
- the portions of the inlet channels 51 arranged in the guide body 50 and blades 48 coincide, whereby the combustible gas mixture is directed into the inner working space 55a.

- the outflow from every inner working space 55 can occur individually, or outs-ide the housing 41 a collecting pipe (not shown) may be arranged for all of the outlets 56.
- the gas mixture flowing into the working space 55a is ignited in a later phase, for example in the working st-age 55b or 55C.
- the channels in the guide body 50 and blades 48 do not longer coincide, but the gas expansion effected by the ignition causes the inner sleeve to continue its rotation in the shown direction of rotation.
- the combfusted gas is blown out when the portions of the waste gas channel 52 in the guide body 50 and blades 48 again coincide, as described above.
- the Working chambers will operate in turn, which results in an extremely uniform power or impulse distribution which in the embodiment shown corresponds to that of a l2-cylinder four-stroke engine (six power irnpulses per revolution).
- a rotary machine is achieved which includes several advantages over known machines of this type.
- the machine may be applied as a pump or engine. In both cases the capacity of the machine can be increased in a simple way without increasing its size, by utilizing an inner working space.
