FIELD: mechanical engineering; piston machines. ^ SUBSTANCE: invention relates to internal combustion engines and compressors. Proposed piston contain ring grooves, spring-loaded compression piston rings exposed to pressure of gas getting from working space of cylinders, and gas channel. Cylindrical inserts are installed over perimeter of ring grooves to accommodate piston provided with rod. Spring-loaded rings are arranged in inserts, and gas pressure onto spring-loaded rings is conveyed by piston and rod. ^ EFFECT: elimination of non-uniformity of specific pressure of piston rings onto cylinder surface over ring generatrix. ^ 1 dwg |
