ABSTRACT:
An actuator and valve assembly is disclosed which comprises an electrically-energizable actuator assembly and a device for communicating, collecting and draining damping fluid with respect to at least one cavity of the actuator assembly. If too much damping fluid remains in the actuator and valve assembly after shutdown, that damping fluid may cool off and cause slow response of the actuator and valve assembly when it is re-energized. The end result is that quick starting and/or operation of the actuator and valve assembly may be hindered, particularly under cold operating conditions. The communicating, collecting and draining means permits at least a portion of the hot damping fluid to automatically drain from the cavity after the actuator and valve assembly has been shutdown.
