Device for achieving variable compression ratio in lifting cylinder motor, has pin whose cylindrical sections are coaxial to each other, and piston pin comprising fixing agents fixed with respect to rotationally fixed piston of motor

摘要

The device has a piston pin (110) provided with three cylindrical sections. The first and third cylindrical sections are coaxial with each other. The second cylindrical section is arranged between the first cylindrical section and the third cylindrical section. A central axis of the second cylindrical section is moved via distance parallel to a common center axis of the first cylindrical section and the third cylindrical portion for forming an eccentric cam. The piston pin comprises fixing agents fixed with respect to a rotationally fixed piston (108) of a lifting cylinder motor (100).
