Abstract

PURPOSE: To improve the engine ability, by means of preventing oil accumulation by eliminating the trouble which is generated on the problem of a mould structure when the engine is in moulding, and of prevening an irregular combustion and the yawing etc. of an engine plug.
CONSTITUTION: In an engine having a carburetor 1, crank chambers 2,2', cylinders 3,3', pistons 4,4' and a crank shaft 5 etc., a path part 10 whose bottom is lowered toward the side of the carburetor 1 is formed for the purpose of taking a releasing inclination when a wall 7 of the main body forming an air absorbing path 6 at the crank chambers 2,2', is moulded in one body, and when the wall 7 of the main body is moulded in a lower path 6" of the air absorbing path 6, and a path part 13 whose bottom is lowered toward the side of the carburetor 1 is formed for the purpose of taking a releasing inclination when a connecting hole 11 of a reed valve 8 is moulded. And, guiding walls 14,15 consisting of triangle pieces becoming to the inversed inclination to the inclination of each path parts 10,13 by the inclined surfaces 14',15' are arranged, thereby the oil accumulation is prevented.
