Abstract
Improvements in hydraulic master cylinders, in particular for motor vehicle brake circuits, of the type that comprise a box, provided with a bore in which a piston slides to define in it a hydraulic pressure chamber adjacent to the front face of the piston, the front face of the piston cooperating peripherally with a fluid-tight seal and with the bore to separate the pressure chamber from a supply port, when the piston moves from its rest position, characterized in that the front face of the piston it has a cylindrical projection, the free end of which is slidably mounted in the bore, by means of a support surface called the front support surface, the axial position of the front support surface with respect to the fluid-tight seal being such that, During the full stroke of the master cylinder piston, none of the super Sliding race faces between the front bearing surface and the bore wall can slide over the joint.
