PISTON ENGINE PROVIDED WITH A MOTION TRANSLATION DEVICE

摘要

The invention relates to mechanical engineering and can be used for developing and using piston engines, piston pumps actuators, piston compressors, transport means and hand and power tools. In the inventive device for converting translational displacement into rotational movement and vice-versa, the conversion of motions from one type into another is produced with the aid of a groove (tongue) which is circularly closed along the helicoidal lines and the conjugation lines thereof on the lateral internal or external surfaces of the device. The inventive piston engine in the variants thereof for the novel use of the method according to the application N DEG 2000107495 RU and carrying out said method according to said application N DEG 2000107495 RU, comprises said device. The working cylinder of the piston engine comprises at least one channel for positive fuel delivering (vapour or gas under pressure) which is arranged between the top dead centre and the low dead centre of the working piston during a cycle. When an auxiliary piston of the piston engine is used in a gas-distributing device, the working cylinder comprises only one window in the displacement area of the auxiliary piston. Said window is arranged above the top dead centre of the working piston during the cycle and is used for supplying atmospheric air or combustion products and for exhaust emission. The window is simultaneously connected to intake and exhaust manifolds comprising valves which are opened by pressure difference between manifolds and the working cylinder, said pressure difference is created by vacuum produced when the working piston moves for the valve of the intake manifold and a gas pressure of a combusted fuel for the valve of the exhaust manifold. Said working cylinder can comprise two windows arranged on the same level in the displacement area of the auxiliary piston above the top dead centre of the working piston during the cycle, one window being linked to the intake manifold and another is linked to the exhaust manifold. Said manifolds comprise the valves which are opened by pressure difference between the manifolds and the working cylinder.
