Throttle valve for adjusting the feeding of a gas to a fuel cell and electric drive vehicle including the throttle valve

A throttle valve (10) for adjusting the feeding of a gas to a fuel cell (3);

• the throttle valve (10) comprises:
• a valve body (12) including a first (12A) and a second portion (12B);
• a gas feeding duct (14) obtained in the first portion (12A) of the valve body (12);
• a throttle plate (15), arranged in the feeding duct (14);
• a shaft (16), which is rotatably mounted in the first portion (12A) of the valve body (12) and supports the throttle plate (15);
• and
• an actuator (8), which is mounted in the second portion (12B) of the valve body (12) and is configured to rotate the shaft (16);
• the throttle valve (10) is characterized in that it comprises:
• a magnetic joint (20), which transmits the motion from the actuator (8) to the shaft and comprises a first half (25) coupled to the shaft (16) and a second half (26) facing the first half (25) and coupled to the actuator (8);
• and
• an insulating wall (27) which is configured to insulate the first portion (12A) of the valve body (12), in a pneumatically sealed manner, from the second portion (12B) of the valve body (12) and is arranged between the two halves (25, 26) of the magnetic joint (20).
