摘要： A valve rotating device with valve stem seal includes a valve rotating device, with a cylinder head rest and a spring rest intended to bear against a valve spring during operation. The valve rotating device is designed to rotate the spring rest relative to the cylinder head rest during operation. A valve stem seal is attached to the cylinder head rest of the valve rotating device. The valve stem seal being designed to bear against a valve stem and to seal same during rotational and axial movements.

摘要： A cover body (2) for a valve rotating device includes a ring-shaped upper part (4) and a ring-shaped lower part (6). The upper part (4) and the lower part (6) are axially spaced apart and are adapted to accommodate an axial spring element (24) therebetween. The upper part (4) and the lower part (6) are connected to one another by at least one connecting piece arranged at the location opposite an insertion position of the axial spring element (24).
A valve rotating device (12) having such a cover body is also provided. A ring-shaped base body (22) has a plurality of pockets (16) oriented in a circumferential direction, in each of which a ball (14) and a tangential spring (32) are arranged. The pockets (16) have a variable depth in the circumferential direction such that inclined raceways (26) for the balls (14) arranged therein are formed. The tangential springs (32) push the balls (14) toward an end of the respective pocket (16). The axial spring element (24) is ring-shaped and a first end of the axial spring element (24) is supported on an ring-shaped stop surface (18) of the base body (22) and a second end of the axial spring element (24) is supported on a surface of the upper part (4) of the cover. A surface of the lower part (6) facing away from the axial spring element (24) rests against the balls (14), and wherein the halls (14) and the axial spring element (24) are arranged overlapping in the axial direction.
A method for producing a cover both (2) for a valve rotating device is also provided.
