In such a piston, an easy to assemble cooling channel cover is achieved in that a one-piece, plastic ring, U-shaped in cross-section, having radially angled outer and inner shanks around the circumference, has at least one film hinge running around the circumference of the ring. The film hinge allows at least one radial deflection of at least one of the shanks, in such a manner that in order to close off the cooling channel, the shanks engage in a stepped conical recess on the inner edge of the cooling channel. ® KIPO & WIPO 2007

摘要： PURPOSE: A piston is provided to achieve an improved engine performance and stable quality of engine by reducing pressure of a second space of the piston so as to thereby prevent an engine oil and air-fuel mixture from being leaked toward a combustion chamber and an oil pan. CONSTITUTION: A piston(15) is constituted by a header(30) and a skirt(31). The header includes a plurality of grooves(32,33,34) for maintaining an air tight contact with a cylinder, and a top land(38), a second land(39) and a third land(40) protruded from the grooves. The header further includes compression rings and an oil ring inserted into the grooves, respectively, so as to form a first space and a second space of the piston. Thus-configured piston is fitted to a cylinder arranged within a cylinder block of an engine and reciprocates vertically. A combustion energy generated from the reciprocation of the piston is converted into a rotational motion and transmitted to a crank shaft.
