Pneumatic switching valve for raising and lowering aircraft fuselage - has pressure-operated control chamber coupled to return pocket via magnetic valve during switch=over to stop position

摘要

Air suspension is used to control positions for lift, lower, go and stop. A throttle (32) for narrowing the flow cross-section is provided in the pipe (31) leading from the return space (27) to atmosphere. The control chamber (26) is connected via the magnetic valve (34) to the return space on switching to the stop positioon. ADVANTAGE - Danger of over-control avoided.
