PISTON MACHINE Russian patent published in 1994 - IPC

FIELD: engine engineering. SUBSTANCE: machine has rotor mounted in bushings for rotation. The bushings are rigidly secured to a case of the machine. Cylinders are rigidly secured to the rotor. The cylinders are provided with pistons. Connecting rods are rigidly secured to the pistons. The rods are connected to crankpin of the crankshaft through bearings. The cylinders are provided with two sleeves. One of the sleeves is fixed and the other is movable. The movable sleeves is provided with lateral slot in the middle. Longitudinal bearing inserts are received in the slot. The inserts enclose the crankshaft. The crankshaft is mounted in bushings with a shift and kinematically connected with the rotor. In the case of internal combustion engine the machine can have two mechanism for forced removing of exhaust gases from the cylinders. The first mechanism has electromagnet valve controlled by electromagnets which are fed from rings-disconnectors. Positioning of the exhaust can be controlled from a cabin immediately. In the second case outlet ports are provided in the movable sleeve. In operating the movable sleeve moves synchronically to the pistons but has half as much speed. EFFECT: decreased sizes. 6 cl, 2 dwg
