Abstract
The device includes a circular array of rolling bodies (2) disposed in sloping pockets formed in a base member (3). An annular spring disc (1) normally presses the rolling bodies (2) fully down into their pockets. In use of the device, a valve spring so stresses the spring disc (1) during valve opening, as to result in the rolling bodies (2) being relieved of loading by the disc (1) under the urging of springs (8) housed in the pockets, these bodies (2) now move up to the shallower ends of the pockets. As the valve closes, the rolling bodies (2) are loaded again by the disc (1) and the resultant rolling of the bodies (2) down into their pockets causes the base member (3) to rotate relative to the spring disc (1). Further rolling elements (6) are interposed between the spring disc (1) and base member (3), intermediate the rolling bodies (2) and the zone of action (7) of the valve spring on the disc (1).
