摘要 |
The valve has a body with seat surface and leaf spring element with counter holder on a clamping surface. The seat surface (5) has a coating of thermal stress bearing elastomer, e.g. fluorcaoutchouc. The valve body (2) has a peripheral rubber ring (11) to generate a sealing action between exhaust gas return pipe and valve body, and for dampened bearing of valve body in the pipe.
