The actuator includes a reciprocating rod connected at one end to a diaphragm and adapted to be connected at the other end to a pivoted lever for actuating the valve. A bearing is provided for the reciprocating rod with the bearing being moveably supported by a leaf spring arrangement mounted on the actuator for absorbing vibrations and transverse movement of the reciprocating rod.
