Pressure increasing unit for motor vehicles has ellipsoidal disc on axial rod in exhaust pipe with disc valve closed by a spring that opens when desired pressure is exceeded

摘要

A pressure-increasing unit for motor vehicles comprises an ellipsoid comprising two half-shells (01,02) on an axial rod (11) with axial inlet or outlet flanges (07,08) installed in an exhaust pipe. The rod passes through a disc valve (03) in the ellipsoid and a coil spring (10) presses the disc against the inlet flange. The valve opens to release exhaust gas when the inner pressure exceeds the spring force.
