FIELD: mechanical engineering; transport engineering; four-stroke internal combustion engines. ^ SUBSTANCE: invention relates to device designed to control inlet and outlet gas mixture in engine. Know designed limit possibilities of four-stroke engine because of their weight and conditions of flow of gas mixture. Proposed invention eliminates all these drawbacks as proposed valve has small weight and provides better conditions of gas mixture flowing. According to invention, inlet and outlet gas mixtures can flow inside valve body. Weight of valve is reduced and higher efficiency is provided owing to the fact that valve stem is not in middle part of flow path. ^ EFFECT: improved conditions of gas flow. ^ 6 cl, 4 dwg |
