DAMPING-ADJUSTABLE SHOCK-ABSORBER WITH A DOUBLE-FRONT-SEALED DEVICE FOR CONNECTION BETWEEN AN INTERMEDIATE TUBE AND A CONTROL VALVE

摘要

The shock-absorber (10) comprises a pressure tube (12), an outer tube (20), an intermediate tube (22) fitted onto the pressure tube (12), a control valve (28) for controlling the flow of a damping fluid to/from the intermediate tube (22) and a sealed connection device (36) for sealed connection of the control valve (28) with the intermediate tube (22). According to the invention, the sealed, connection device (36) comprises a spacer body (40) axially interposed between the intermediate tube (22) and the control valve (28), a first front sealing member (48) in contact with a front face (44) of the control valve (28), and a second front sealing member (54) in contact with the outer cylindrical surface of the intermediate tube (22), in such a manner as to form a double front seal between the control valve (28) and the intermediate tube (22).
