| description | Valve for an airbag system for a motor vehicle and airbag system for a motor vehicleThe invention relates to a valve for an airbag system for a motor vehicle, having:a housing (20) which extends along a longitudinal axis (21) and surrounds a cavity (22) having a taper (17) and surrounds a control chamber;an electrically switchable pilot valve (15) which selectively seals or releases a pilot opening (6) of the control chamber (5);a piston (3) which is arranged in the cavity (22) and can be displaced along the longitudinal axis (21) relative to the housing (20);an equalization line (4, 18) which connects an inlet (1) of the valve (100) to the control chamber (5) for fluid communication, wherein:a sealing seat (2) is formed at the taper (17) in order to block a gas flow from the inlet (1) to an outlet (14) of the valve (100) in a closed position, in which the piston (3) is in contact with the sealing seat (2), and to release said gas flow in further positions;the control chamber (5) is arranged on a first side (24) of the piston (3) facing away from the sealing seat (2); andthe piston (3) has a first diameter on a side (23) facing the sealing seat (2) and a second diameter (26) on the first side (24), the first diameter (25) being less than the second diameter (26). |
