Abstract

Eine Ventildrehvorrichtung zur Erzeugung von Drehungen eines Gaswechselventils eines Verbrennungsmotors umfaßt den Ventilschaft mit einem Grundkörper, der mit mehreren in Umfangsrichtung orientierten Taschen zur Aufnahme von Wälzkörpern versehen ist. Der Grundkörper ist mit einem Deckel versehen, der gleichzeitig als Ventilfederauflage dient. Zur einfacheren und kostengünstigeren Herstellung von Grundkörper und Deckel sind diese aus umgeformten Blechteilen gefertigt.

Figure 00000001
A valve rotating device for generating rotations of a gas exchange valve of an internal combustion engine comprises the valve stem with a base body which is provided with a plurality of pockets oriented in the circumferential direction for receiving rolling bodies. The base body is provided with a cover, which also serves as a valve spring support. To simplify and cost-effectively manufacture the base body and cover, they are made from formed sheet metal parts.
