Abstract
An actuator for operating a driven device in an emergency comprises: an actuator mechanism having a cylinder, a piston slidably disposed within the cylinder and coupled to the driven device, an operational chamber defined by the cylinder and piston, and a passage communicating with the operational chamber; a high pressure gas generating source comprising a container vessel having an opening, a high pressure gas generating medium contained within the vessel, and a sealing member for sealing the opening of the vessel; and unsealing means operating in response to an emergency operation signal from the outside to unseal the sealing member of the high pressure gas generating source. High pressure gas from the high pressure gas generating medium flows through the opening and passage into the operational chamber upon unsealing of the sealing member of the high pressure gas generating source and operates the piston thereby to drive the driven device.
