FIELD: machine building. ^ SUBSTANCE: engine consists of crank shaft with radius of crank equal to quarter of piston stroke, of mounted of crank shaft eccentric with eccentricity equal to quarter of piston stroke and of slide put on eccentric and resting on side surfaces of carter. The slide is coupled with the piston by means of a rod. To pass dead points the mechanism is equipped with holders in form of spring-loaded rollers facilitating rotation of the crank shaft only in one direction, and rotation of eccentric - into an opposite one. For example, a stop is installed on the eccentric in form of an involute tooth or a cylinder pin, while response recesses are made on the carter. ^ EFFECT: raised efficiency and resource of engine due to reduced friction of pistons against walls of cylinder. ^ 3 cl, 13 dwg |
