Abstract
A throttle valve for adjusting the feeding of a gas to a fuel cell, which includes: a valve body, divided into a first and a second portion; a gas feeding duct obtained in the first portion; a throttle plate arranged in the feeding duct; a shaft which is rotatably mounted in the first portion and supports the throttle plate; and an actuator which is mounted in the second portion and is configured to rotate the shaft. The throttle valve further comprises a magnetic joint, which transmits the motion from the actuator to the shaft and is divided into a first half coupled to the shaft, and a second half facing the first half and coupled to the actuator. The throttle valve also includes an insulating wall which insulates the first partition, in a pneumatically sealed manner, from the second portion of the valve body and is arranged between the two halves of the magnetic joint.
