ABSTRACT:
A valve driving apparatus for impartation of a motive force to a valve component which employs a flexible drive member intermediate the actuator member and the valve component to be moved. The flexible drive member is capable of storing energy momentarily so that the speed of movement of the actuator member and the speed of movement of the valve component may be different, preferably with the motion of the valve component being slower than the motion of the actuator member. In the preferred embodiment, the actuator member, flexible drive member, and valve component operate substantially on a common axis.
