Device for use in exhaust gas recirculation system of thermal engine of motor vehicle to transform rotational movement of wheel into translation movement of valve element, has cam passage connected to valve element

摘要

The device (6) has a body (9) formed as a single piece, and a tubular guiding wall (7) arranged in pivot-sliding connection with a tail section of a valve element, where the body is anodized. A cam passage (11) is formed in a tubular cam wall (10). The cam passage is connected to the valve element. The body comprises a tubular seat wall (24) that is provided with a seat (25) for the valve element. Two lip joints (27) are arranged in a central thickness portion (22) to cooperate with the tail section. The body is made of wrought alloy. Independent claims are also included for the following: (1) a method for fabricating a movement transformation device (2) a valve comprising a rotary actuator.
