Beschreibung
Zusammenfassung:	FIELD: pneumatics, applicable as an actuator of door leaf opening - closing of buses and trolleybuses. SUBSTANCE: the door pneumatic drive has a pneumatic cylinder, air distributor and an emergency valve connected by flexible pipe-lines. To prevent a loss of force at the door leaves at an emergency loss of pressure in the pneumatic system, a shut-off valve automatically closing the air pressure in the working cavity of the pneumatic cylinder is built in the working cavity of the pneumatic cylinder responsible for closing of the door leaves. EFFECT: enhanced reliability. 1 dwg
