Description

A rotary internal combustion engine (ICE) is two-section with two compression chambers parallel to each other and inclined to the projection of the shaft axis, located above the engine casing with gas distribution.

The second version of the engine is single-section, also in two compression chambers, parallel to each other and perpendicular to the projection of the shaft axis, located above the engine casing and with gas distribution.

Both engines achieve compact design, smaller dimensions and weight.

The invention relates to mechanical engineering of rotary ICE for any purpose.

Known rotary ICE, patent RU 2315189 C2. The engines have: a fixed two-section housing divided by a transverse partition into two sections; two-section rotor with a radial groove; the separation element of the working chamber between the rotor and the housing is a three-layer sliding gate with a labyrinth seal installed in the rotor groove with the possibility of radial movement to form variable volume chambers for gas inlet, compression, expansion and exhaust, respectively; two compression chambers parallel to each other and inclined to the projection of the shaft axis, located in the thickened part of the housing, with two-sided cut-off them from the respective chambers of variable volume by valves; U-shaped seal in the housing, in the area of constant linear contact of the rotor with the housing along the cylindrical generatrix and continued along the end surfaces from both sides to the rotor shaft. Gas distribution of the engine is carried out by four valves - the transfer of gases from the chambers of variable volume (KPO) to the compression chambers (KS) and from the KS to KPO, and two spools, one - the intake of fresh air or a combustible mixture in the KPO, the other - the release of exhaust gases from the KPO, for actuating valves and spools, the engine has a camshaft, two support rollers, four rocker arms for valves and two for spools, as well as two gear sectors with springs for spools. Spools have a flat cut along the length of the windows. The motor housing has eccentric internal and external surfaces.

The disadvantage of these engines is located above the body valve timing, which increases their size and weight.

The purpose of the invention is to reduce the size and weight of the engine.

The goal is achieved by using only spool valve timing, as well as using a concentric body shape instead of an eccentric.

In another embodiment, the goal is achieved in addition to the gas distribution and concentricity of the housing surfaces by the absence of a transverse partition in the housing, i.e. single-section engine.

SUMMARY OF THE INVENTION The cylindrical housing of the engine has concentric outer and inner surfaces with tides for the spools. Engine gas distribution is carried out completely by two spools, each of which, in its length equal to the respective windows, has two through cuts dividing the outer circumference of the spool into four equal parts, and at an angle of ninety degrees relative to each other. Two compression chambers, with their two-sided cut-off from the corresponding volume chambers / KPO / slide valves, are located above the engine casing, parallel to each other and inclined to the projection of the engine axis. The cycle of working processes of a two-section engine is carried out in one revolution of the engine shaft, in one section - suction and compression, in the other - stroke and exhaust. In compression chambers, compression and expansion processes alternate through one revolution of the motor shaft, i.e. cycle for two shaft rotations.

In another embodiment, the engine housing is also cylindrical and has concentric outer and inner surfaces with tides for the spools, the compression chambers are perpendicular to the vertical central plane of the engine above its body, the gas distribution is carried out by two spools having three separate channels, each of which has its own the length of two cutouts in the dimensions of the corresponding windows and at an angle of ninety degrees relative to each other, moreover, in the two extreme channels, the cuts are a quarter ok guns, and in the middle channel a cutout in half a circle. The engine is single-section. The cycle of engine work processes in pairs takes place in four revolutions of the shaft, i.e. one revolution - suction and exhaust, the second revolution - suction and compression, the third - stroke and compression, the fourth - stroke and exhaust.

Thus, a rotary internal combustion engine containing a two-section cylindrical fixed housing, divided by a transverse partition into two sections with inlet and outlet windows, in each section there is a rotor with a radial groove rigidly connected by a common shaft and placed in the corresponding sections with surface contact in the end and linear in the cylindrical parts of the housing, the element for separating the working chamber between the housing and the rotor is a three-layer sliding gate for a tight permanent fit to housing, with a labyrinth seal, mounted in the radial groove of each rotor with the possibility of radial movement to form chambers of variable volume, a U-shaped seal in the housing in the area of constant linear contact of the rotor with the housing along the cylindrical generatrix and extending along the end surfaces from both sides to the rotor shaft , two compression chambers, and as a gas distributor the engine has two spools, characterized in that the spools are made in the form of cylindrical rods with slots in the dimensions of the case windows , the full cycle of processes in both sections occurs in two shaft rotations, in one section - suction through a non-locking inlet window and compression, in the other section - a stroke and exhaust through a non-locking exhaust window.
