Abstract
A shaft device for a bellows-type gas meter. A first eccentric cam assembly and an element having a radial groove are both coupled to the shaft. A second eccentric cam assembly having an opening is placed on the shaft. A rotatable insert element is inserted in the opening in the second eccentric cam assembly. A follower is provided on the insert element for engaging the radial groove in the element coupled to the shaft. A radial protrusion is provided for axially locking the shaft by rotating the insert element. The angle between the centerline of the first eccentric cam assembly and the centerline of the second eccentric cam assembly is adjusted by rotating the insert element.
