<p>The valve (10) has a filter unit (16) arranged inside the safety valve. The filter unit takes two different end positions based on dynamic pressure in the safety valve. A bypass is released in one of the two end positions. Compressed air reaches over the bypass by evasion of the filter unit from a compressed air input (12) to a compressed air exit (14). The filter unit has a bevel at its input opening. An effective area of the safety valve becomes larger during increasing flow rate, to keep the dynamic pressure constant. An independent claim is also included for a pneumatic gearbox control for a commercial vehicle.</p> |
