Abstract
A valve rotating device has an annular main body, an annular cover body, and an annular axial spring element. The main body has multiple pockets of variable depth so that raceways are formed for balls situated therein, wherein tangential springs press the balls against ends of the pockets in the circumferential direction. The cover body is rotatable relative to the main body about an axis and is axially displaceable, and has an annular first support element, an annular second support element, and a connection, wherein the support elements are axially spaced apart from one another and the connection connects the support elements so that they are fixed relative to one another. The axial spring element at a first end rests on an annular stop surface of the main body, and at a second end rests on a surface of the first support element, wherein the axial spring element is situated between the first support element and the second support element. A surface of the second support element facing away from the axial spring element rests against the balls, and the balls and the axial spring element are arranged in an overlapping manner in the axial direction.
