摘要： The invention relates to a control device for controlling a pneumatic component, the device including a compressed air supply circuit for connecting to an inlet of the pneumatic component. The circuit comprises both a normally closed monostable valve having an inlet for connecting to a compressed air source and an outlet for connecting to the pneumatic component, and also a bistable directional valve having both a first port for connecting to the compressed air source and also a second port connected to a first port of a normally passing monostable directional valve, the monostable directional valve having a second port connected to a pneumatic control port of the monostable valve; the bistable directional valve is capable of adopting a passing state in which a connection is created between the first port and the second port of said directional valve, and a non-passing state in which the first port and the second port are disconnected from each other; and the monostable directional valve is capable of adopting a rest state in which a connection is created between the first port and the second port of said directional valve, and an exhaust state in which the second port of said directional valve is connected to an exhaust outlet.
