Abstract

The actuator has two pressure-fluid cartridges (1,2), each comprising a piercing piston (3,4) as an energy carrying unit. Discharge pressure chambers (16,17) are associated with the pressure-fluid cartridges and can be connected to actuators of the ventilation flaps. Associated with the discharge pressure chambers is a safety valve (15) which works depending on pressure and which controls one or more pressure-relief passages (20,19,21). The safety valve bearing against the two piercing-piston housings is held by these.
