FIELD: transport. ^ SUBSTANCE: hydraulic damper comprises high-pressure tube 10. Piston 14 divides tube 10 into compression chamber CC and draft chamber CT communicated via piston 14. Hydraulic fluid tank 14 communicates with compression chamber CC. Control valve VC communicates draft chamber CT with tank 20 and comprises tubular case 40 with radial channel open toward tubular case inner chamber and tank 20. Locking rod 60 displaces axially in tubular case 40 between control valve open and closed position to communicate draft chamber CT with tank 20. Actuator A displaces locking rod 60 in tubular case 40. ^ EFFECT: higher tightness, fine adjustment. ^ 23 cl, 12 dwg |
