Abstract

FIELD OF THE INVENTION The invention relates to engine-building and makes it possible to reduce the force interaction of the rotors with the housing. In the rotary-piston engine there are three rotors: two lateral 5 and 6, installed in a fixed housing at the same angle to the axis of the central rotor, and central made in the form of a disk, having pistons 11 in the form of spherical segments rigidly and symmetrically mounted on it. On the side rotors there are similar pistons 13, which are symmetrically mounted on them in alternating order with the pistons of the central rotor. In the central and lateral rotors 5 and 6, cuts are made in the form of pistons coupled to them. In the housing there are two combustion chambers 17 connected by passage and outlet channels with variable volumes at the pistons of the central rotor and side rotors. The side rotors 5 and 6 are mounted in the housing symmetrically to the plane of symmetry of the central rotor, and the central rotor is rigidly mounted on a straight shaft mounted in bearings located on the side walls of the housing. 2 hp ff, 3 ill.

Description

IfufS

The invention relates to a diesel engine and can be used as a power plant for various purposes.

The purpose of the invention is to reduce the force interaction of the rotors with the body, by the way. reducing the surface area of the rotors, perceiving the pressure of the working fluid, and reducing the uneven load on the rotor bearings.

Fig, I shows the engine, a longitudinal section; figure 2 - section aa in figure 2; on fig.Z - part of the engine sweep. "

The engine contains a stationary body 1 with side walls 2, in cavity 3 of which three rotors with pistons are formed with variable volume chambers: a central 4 made in the form of a disk and two side 5 and 6 mounted on hollow conical bushings 7 whose axes located at the same angle to the axis of rotation of the central rotor.

The engine also has gas exchange organs with inlet 8 and exhaust 9 channels connected to chamber 10. The pistons 11 of the central rotor 4 have the shape of spherical segments and are installed on both sides of the disk on its flat surfaces in pairs symmetrically with respect to the plane 12 of symmetry of the engine, perpendicular disk axis. The pistons 13 of the lateral rotors 5 and 6 are also made in the form of spherical segments and are located symmetrically with respect to the plane 12. The pistons 31 are installed in alternate order with the pistons 13. In the central 4 and lateral 5 and 6 rotors there are corresponding cuts 14-16, made in the form of pistons 11 and 13, opposite them and conjugated with them when combined (.fig.z).

Gas exchange organs include two combustion chambers 17 with spark plugs 18, a bypass channel 19 and individual channels through 20 channels located in a housing symmetrically with the plane 12. In the latter, the axis of the bypass channel 19 is located, which can be periodically communicated with variable volume chambers 21 The pistons 13 of the lateral rotors 5 and 6 are located, the output channels 20 of the combustion chambers 17 are made with the possibility of a period of 5

The communication with variable volume chambers 22 is located between the side surfaces of the pistons 11 between them and the side walls 1g 2 of the housing 1. On the side opposite to the combustion chambers 17, the exhaust channels 9 of the engine are located in its side walls cp.

The rotor 4 and the pistons 11 are made to periodically overlap the inlet channel 8, the axis of which is located in the plane 12. The cutouts 16 in the rotors 5 and 6 are designed to periodically communicate with the exhaust channels 9. To reduce leaks and leakages through the mating surfaces in alternating chambers volume used known means of sealing. For example, spring-loaded plates 23 are installed between pistons 11 and 13. Angular regulators of the central rotor 4 with pistons 11 and lateral rotors 5 and 6 with pistons 13 in the longitudinal, engine section are made the same. The rotor disk 4 is rigidly coupled to an output straight shaft 24 mounted on bearings 25 located in the side covers: 2 bodies. The engine also has means of synchronizing the movement of the rotors.

The engine works as follows.

During rotation of the rotors 4-6 of the variable volume chamber 21, the fuel-air mixture is sucked through the outflow channel 8, which, with further rotation of the rotors, is injected; cutting the bypass channel 19 into the combustion chambers 17, in which, after separation from these variable volume chambers 21, is ignited by the spark plugs 18. The resulting working gases flow through the outlet channels 20 into the chambers 22. of variable volume and are emitted after expansion through the exhaust channels 9 into the atmosphere.
