ROTARY PISTON INTERNAL COMBUSTION ENGINE Russian patent published in 2014 - IPC F02B53/08 F01C1/12 

FIELD: engines and pumps.

SUBSTANCE: invention relates to propulsion engineering. A rotary piston internal combustion engine comprises a body, a guide shaft with a front tooth, a rear tooth and a partition between them, front and rear slave shafts with gates having a groove for a tooth. The body is divided into front and rear sections with rotation of the front section relative to the rear section around the axis of the guide shaft in direction of its rotation by the angle of 135°. Opposite to a compressing chamber in the front section near the tooth there is an input hole of the channel in the partition, which leads to a radially directed valve hole arranged in the middle part of the partition. In the middle of the angle of sections rotation at the distance remote at one side from the line of crossing of cylindrical surfaces of the front section, equal to the sum of widths of a seal and an input hole of the channel, and at the distance remote at the other side from the line of crossing of cylindrical surfaces of the rear section, equal to the width of the seal, there is a segment bore located in the body and designed for contacts of the spark plug and the combustion chamber. The end of the segment bore is arranged opposite to the middle of the partition for communication with the valve hole of the channel as the latter is located opposite to it. Opposite to the edges of the partition in the body there are grooves with sealing rings. The edge of the tooth top, which is front along with the rotation of the guide shaft, in the front section, and the rear edge of the tooth top in the rear section are on the same line. Thickness of each tooth is equal to the sum of widths of the seal, the input hole of the channel, the segment bore.

EFFECT: invention is aimed at increased efficiency of an engine.
