Valve mechanism control device and method and process for fixing return spring device

1. The present invention relates to a valve mechanism control device. In addition, the present invention relates to a method for fixing a return spring device of a valve train control device.

Background technique:

2. Valve train control equipment is known, for example, from de 10 2018 108 271 a1. A valve train control device of an internal combustion engine is described therein. The valve train control device has at least one valve in each cylinder, and the valve lift of the valve is respectively preset by at least one cam of a camshaft. The valve lift can be selectively shut off or switched to another lift direction by the axial movement of the switch pin protruding from the side wall via the switchable tow bar, wherein the switch pin of the tow bar is connected to at least one thrust via a leaf spring The element is connected, the thrust element is arranged in the cylinder head parallel to the camshaft and can be moved longitudinally from the rest position to the switching position via the linear actuator against the return force of at least one return spring device. The return spring device for returning the thrust element to its rest position includes a coil spring which is arranged on the actuator side end of the thrust element between the angled end and the outer wall of the cylinder head of the internal combustion engine . The coil spring is accommodated on a guide sleeve which is pressed into the guide hole of the thrust element.
