Gasket device and pneumatic valve system for a commercial vehicle

A pneumatic valve system, for a use in commercial vehicle, said pneumatic valve system comprising:

• a gasket device comprising:
• a gasket part being adapted to be inserted into at least a groove of a flange face of a first casing part,
• at least one gasket chamber for sealingly connecting channels of a mounted second casing part,
• a body part being adapted to be received in a valve seat of said second casing part, and
• at least one spring part connecting said body part and said gasket part,
• wherein said body part is moveable in an airflow direction relative to said gasket part by bending or stretching said at least one spring part,
• wherein in an unbiased basic condition of said gasket device said body part is positioned above a gasket plane defined by said gasket chamber,
• wherein said gasket device is made as a single part of a flexible, elastic material,
• the first casing part comprising a first flange face and at least one first air flow channel, and
• the second casing part comprising a second flange face and at least one second air flow channel,
• wherein said at least one first air flow channel and said at least one second air flow channel are sealingly connected by said at least one gasket chamber of said gasket device,
• said gasket part of said gasket device being inserted into at least one groove of said first casing part and at least one groove of said second casing part, and
• said body part being pressed against the valve seat of the second casing part, thereby realizing a check valve,
• said check valve allowing an airflow in an airflow direction and blocking in the reverse direction
• wherein said pneumatic valve system is an air supply system for a use in a commercial vehicle, and
• wherein said first casing part is an adapter and said second casing part is a solenoid valve device comprising at least two solenoid valves.
