ABSTRACT:
The booster comprises, in a radial opening (21) of the valve body (6), a first positioning member (22) fastened in the valve body and a second positioning member (23) interposed between the first positioning member and an interacting shoulder (19) of the valve plunger (14), the second positioning member (23) internally associated in a hinged connection with the first positioning member and having an outer end zone (30) interacting, in a rest position of the booster, with a stationary surface (31), with which the piston structure (2-5) also interacts by coming up against it, to assign to the valve plunger (14) a specific rest position relative to the valve body (6).
