Air compressor device for motor car, has valve comprising valve element for changing pressure-controlled operation behavior of valve against another valve, where valve element is designed as spring element with different rigidities

摘要

The device (10) has valves for mechanically controlling an intake flow or an outlet flow. The valves are formed as non-return valves (12) such as flutter valves. One of the valves comprises a valve element for changing a pressure-controlled operation behavior of the valve against the other valve. The valve element is designed as a spring element with different rigidities and as a valve seat with different non-uniform broken edges. Multiple displacement pistons (68, 69) are arranged around a rotation axis (67), and include connecting rods (70).
