Master cylinder with hydraulic reaction dynamics governed by a difference of the sections

摘要

"Master cylinder with hydraulic reaction dynamics governed by a difference of the sections", which consists of a central piston plug (4),Subsequent to the tappet slider (3) according to the first direction (s +) and equipped with a radial extension (41) requested against an internal table (121) of the main piston by a first elastic force theRientada according to the first direction, the piston central plug (4) and, on the other hand,A front face (42) oriented towards the first direction and taking a seat plug (43); a piston (5) with reaction steps and hollow.Presenting a first internal section (51) in which the piston central plug (4) is mounted for sliding watertight.In the second section internal (52) succeeding the first section in the first direction and an internal external section (53) sliding in watertight manner the secondary hole (120).This piston (5) being requested by reaction with a second elastic force oriented in a second direction (s -) inverse to the first direction and intensity lower than the first elastic force.To a rest position in which it is in support against radial extension (41), the piston (5) by reaction in turn the tappet slider (3), according to the second direction (s).Against a stop mobile (81) moving with the radial extension (41).
