Description

 The invention relates to engine building, and in particular to structures of rotary piston internal combustion engines, and can be used as power plants of various machines.

 Known engines with a rotating cylinder block (US patents 2990820, M. CL F 02 B 57/00 and 3499424, M. CL F 02 B 57/00) containing a stationary housing, a rotating cylinder block (rotor) with pistons and gear -Crank-connecting rod power mechanism. The engines are compact, well balanced, however, in terms of fuel consumption they have no advantages over conventional internal combustion engines. In addition, their constructive scheme does not provide for the use of three, six, nine and another number of pistons, a multiple of three, as well as the use of pressurization of air and continued expansion of exhaust gases.

 The invention is aimed at improving fuel efficiency and improving engine speed.

 The solution to this problem is achieved in that the design of the engine with a rotating cylinder block provides for the use of double-acting pistons and a change in the gear ratio of the power mechanism gears.

 The inventive engine is characterized in that it has pistons moving in the sleeves of antifriction material and separating the cylinders into the supra-piston and sub-piston cavities, which allows to reduce friction losses and organize air pressurization, as well as the gear ratio of the fixed and movable gears (three instead of four), which makes it possible to apply three, six, nine, etc. pistons and organize a cycle with continued expansion of the exhaust gas.

 The engine (see drawing) contains a fixed housing 1 in which a movable (rotating) cylinder block 2 with pistons 3 with rods 4 mounted in bushings 5 made of antifriction material is installed. Pistons 3 are connected to the pinion gears by means of fingers 6 and connecting rods 7. The latter are movably fixed in the cylinder block 2 and are meshed with the stationary gear 9. In the housing 1 there are made inlet 10 and outlet 11 and 16 windows connecting to the over-piston 12 space each cylinder during rotation of the cylinder block 2. The piston cavity 13 is connected to the atmosphere through holes in the cylinder block and windows in the side covers of the housing 1 (not shown). In the housing 1 holes are made, interconnected by a pipe 14, and a threaded hole for the spark plug 15.

 The engine operates as follows. When the rotor 2 is rotated, the pistons 3 move in the radial direction due to the gear-crank mechanism and at the same time rotate together with the rotor. Change over-piston volume 12 is used to organize the workflow. When moving the piston 3 to the center of the rotor (to the bottom dead center) at the moment of coincidence of the cylinder with the inlet window 10 under the influence of rarefaction, the fuel mixture is sucked into the over-piston space. Rotating, the rotor 2 overlaps the inlet window 10, the piston 3 moves from the center to the periphery and compresses the fuel mixture. When it approaches the top dead center, a spark jumps between the electrodes of the spark plug 15 and the working mixture ignites. Then there is an expansion of the gases formed during the combustion process and a working stroke is carried out, during which the movement of the piston 3 to the center of the rotor under the action of gas forces is converted into the rotational movement of the rotor 2 by means of a power mechanism. At the same time, part of the gases from the cylinder flows through pipeline 14 to the next (in the direction rotor rotation) cylinder and thus their continued expansion is carried out (simultaneously in two cylinders). After that, the piston again moves to the periphery and the exhaust gases are ejected through the exhaust window 11 (if the cylinder coincides with it) into the atmosphere. Gases are ejected from the second cylinder through window 16. The described processes in the remaining cylinders proceed similarly.

 The use of continued expansion increases engine power without increasing fuel supply, i.e., increases its efficiency. The under-piston space 13 is used to suck in air and pressurize it into the combustion chamber (into the over-piston space) and increase power.
