Compound movement elliptic valve cylinder head

摘要

The invention aims at achieving better filling of the cylinders located in the body of the valve (1) by implanting valves (2) with an elliptical head (3) whose linear opening/closing movement is complemented by a lateral rotation with a 55° amplitude, said rotational movement being accomplished by using a guide (8) having two symmetrical and helicoidal tracks (9) on which two pivots (10) that are provided for said purpose can slide on points diagonally opposite to the stem pertaining to the corresponding valve (2). The overhead with the composite movement elliptical valves can be used in all internal combustion engines such as spark ignition or compression ignition internal combustion engines regardless of the number of cylinders and their utilization.
