Abstract: An automobile exhaust valve is provided, in particular for an automobile combustion engine and more particularly for an embodiment of an implementation of a gas passage shutter. A valve body defines a gas circulation passage along a longitudinal axis and is composed of only two identical half-bodies whose axes, parallel to the longitudinal axis, are offset radially, in order to define inside the valve body two seats on which sides of the gas passage shutter come into flat contact in a closed position. An exhaust pipe equipped with such a valve, and a vehicle equipped with such an exhaust pipe, are also provided.

Abstract: A valve comprises a valve body delimiting a passage for exhaust gases, a flap arranged in the valve body, and a drive shaft configured to drive the flap, and which is integrally secured to the flap. At least one guide bearing is configured to guide the drive shaft of the flap in rotation in relation to the valve body, and is connected to the valve body. The valve also includes an actuator and a transmission comprising an adapter rigidly attached directly to the drive shaft of the flap. The transmission is arranged in order to transmit a motor torque between the actuator and the adapter. The adapter has a contact surface that is in sealed contact with a complementary surface provided on the guide bearing.
