ABSTRACT:
The valve rotator comprises a body to be attached to and rotatable with the valve. The body has at least one groove therein extending partially around said valve stem. Shiftable means is disposed within the groove. A collar receives the valve spring biasing force and encircles the valve stem adjacent the body. The body and the collar are movable in axial and rotational directions relative to each other. A pair of spring washers encircles the valve stem and is interposed between the collar and the shiftable means. One of the spring washers has a portion bearing on the shiftable means and another portion bearing on the body when the valve is closed. The other of the spring washers acts between the collar and the another portion of the one spring washer and has a first portion which overlies the another portion of the one spring washer when the valve is closed and a second portion spaced at least in part from the one spring washer when the valve is closed. Each of said spring washers has an inner circumference and an outer circumference. The overlying portions of the one and the other of the spring washers cooperate with each other adjacent the inner circumferences thereof to transmit surges of the valve spring from the collar through the overlying portions of the one and the other of the spring washers to the body to thereby isolate surges of the valve spring from the shiftable means.
