The torsion spring element, designed as a helical spring, has two spring wire ends constructed as spring legs (6,7) extending tangentially or radially to the windings of the spring element. The whole axial length of the spring element (1) is smaller than the sum of the spring wire diameter (d) or all the individual windings (2). Each winding of the helical spring has a different diameter than the winding following it. The diameter of the windings from both axial ends (3,4) increases in the direction of the middle (5) of the spring. An independent claim is included for an actuating device for operating components in internal combustion engines, whereby the actuating device is coupled to a torsion spring in such a way that with rotation of a shaft energy is stored in the spring so that the spring can return to a predetermined initial position. |
