VALVE FOR VENTING THE INTERIOR OF A ROTATABLE HOLLOW ELEMENT Abstract of the Disclosure A valve for venting the interior of a rotatable hollow element which is at least partially filled with liquid comprises a valve member which is movable transversely with respect to the axis of rotation of the rotatable element into and out of engage- ment with a valve seat to open and close a valve passage in which the valve seat is formed. A spring maintains the valve member in closed position when the rotatable element is at a stand-still. The valve passage has one end opening within the hollow member offset from its rotatable axis and the other end opens to the exterior of the element. The major portion of the mass of the valve member is also offset from the axis of rotation but in a direction opposite from the end of the valve opening. The mass of the valve member is such that at a predetermined rotary speed centrifugal force acting against the valve member will overcome the spring force to move the valve member away from the valve seat and to open the valve passage. -1-
