Abstract
The invention relates to a pneumatic brake-booster comprising, in series, a control rod (10) substantially fixed to a plunger (12) by a pivot mechanism (14), a reaction disk (16) and a push rod (18), the control rod (10) actuating a three-way valve with two seats (24, 26), s specific space being provided at rest between the reaction disk (16) and the plunger (12). According to the invention, one of the two seats of the valve consists of the end of a sleeve (30) coaxial with the plunger (12), a prestressed compressible mechanism (32) tending to shift the sleeve (30) and plunger (12) axially away from one another, the sleeve (30) coming axially up against one end of a piece (36) fixed to the control rod (10) after the relative positions have been set.
