Piston with central valve for hydraulic brake.

The invention relates to a piston with a central valve, particularly for AMPLIFIERS HIDRAULICOS. PISTONS ARE KNOWN TO HAVE A INSERCION (6) VALVE consisting of a INSERCION (8) radially SURROUNDED BEARING A SEAT (7) valve. HANDICAP OF SUCH INSERTS VALVE IS THAT NOT ENOUGH POWER CONNECTION between the two elements in the axial direction in some cases. TO HELP SOLVE THIS PROBLEM, THE INVENTION INTENDS TO CUT LESS, SO THE SEAT (7) interacts VALVE INSERTION (8) BEARING FROM BACK IN BOTH DIRECTIONS. In an advantageous OF THE INVENTION DEVELOPMENT, insertion (6) valve is disposed symmetrically AND HAS A PROJECTION SEALING ON PROFILING valve seat. GUIDE PUSHER (19) VALVE IS PROVIDED IN THE SAME PISTON (1).
