Abstract
In order to solve the problem of the passing of an elbow piece (15) with a right-angle bend (16) through an opening (21) in a seal (19), said seal (19) is provided with a deformable slot (20). The tightness of the system, consisting of the seal (19) and the elbow piece (15), results from the existence of fir-branch shaped protrusions (27) on the base (26) of the elbow piece (15).
Claims10
Pneumatic servobrake, comprising a front chamber (1), capable of being connected to a vacuum source (2), a rear chamber (3), which can be connected to a high-pressure supply inlet, a moving tight partition wall (6) between said chambers, a moving set (8) carried along by the partition wall and connected to a hydraulic braking circuit (10), a device (4) provided for the supply of the rear chamber with a high-pressure fluid at the time of a braking operation, a seal (19) for a passage through the tight partition wall, and a hollow bent tube (13) passing through the seal, characterised in that the seal comprises a slot (20), which can be distorted to some extent for the passage of a bend of the hollow bent tube.
