摘要

The valve has a body for connecting an air intake circuit of an engine to a gas exhaust circuit. An electrical motor (4) controls the valve by displacing a valve tube (3) in the body. A crown (10) is placed at a junction between an inlet channel and a bent part (12) of the body. The valve tube comprises a head (5) that is in contact with the crown. An annular electrical resistor (11) heats the crown by Joule effect.
