Additional supply for vehicle exhaust - has non-return valve element with bi=metallic strip closing supply line at predetermined temperature

摘要

The supply has a non-return valve in the exhaust end, designed such that the valve (2) has an element (5) closing the supply (1) at a predetermined exhaust gas temp. The valve element has a temp. dependent change in shape, closing the cross-section of the supply or valve housing (3). This change of shape occurs via the action of a bi-metallic strip (6) located against a planar wall section. The bi-metallic strip has a straight right-angular profile, located in a square section housing. The housing connects to a circular pipe (1) via diffusor type connections (4). ADVANTAGE - It provides a simple, reliable valve operation.
