Abstract
The valve (110) comprises a hollow body (111) with gas passage ducts (112, 119), flow control elements (122a, 122b) for the ducts, at least one translatory actuator (125) to move the control elements, at least one kinematic transmission to connect the actuator to a permanent magnet (132), which is arranged within the gas passage region and turned by a step motor (137) arranged outside the gas passage region. The flow control elements comprise at least one closure plate for a corresponding port formed in a partition which is interposed in the ducts. The plate supports a sealing gasket on a surface which faces the partition, and is rigidly coupled to a stem of an armature magnet which, in an inactive condition, pushes the plate into a position to close the port. The permanent magnet is cylindrical and supports a shaft, which is keyed to it and is provided for kinematic connection to the actuator. The shaft has one end that lies opposite to an end for keying to the permanent magnet being inserted in a corresponding dead hole form at a base of the hollow body.
