<p>The regulator has an inlet aperture (2), an outlet aperture (3), a valve seat (4), a closure means (5) co-operating with the valve seat (4) and actuated by a diaphragm (6), and a calibrating spring (7) acting on the diaphragm to push the closure means into the open position, and is characterised by a device sensitive to a variable, e.g. temperature, and controlling an actuator, such as an armature (12) of electromagnet (11), acting on the closure means against the action of the calibrating spring (7). <IMAGE></p> |
