<p>The assembly (27) has an actuator i.e. magnetic coil (55), for activating damper-valves (53). A discharge outlet (61) of the damper-valves is connected parallel to an emergency operation valve (69a) by an emergency operation channel (63a) i.e. radial channel. The emergency operation valve is connected parallel to another emergency operation valve (69b), where the latter operation valve has different opening characteristics from the former operation valve. The former operation valve has a valve body (75a) that is biased by a spring (71a) in a closed position.</p> |
