Abstract: The invention relates to a brake force transmission device for a brake force amplifier with an elastic reaction element (7), an input body (22), with an associated working surface (d4), an output body (24), with an associated working surface (d4), with a first transfer ratio, defined by a working surface ratio, actively dependent on the reaction element (7). The aim of the invention is to provide a means, of simple construction, where possible arranged in the form of an assembly, which gives the driver of a motor vehicle increased support when high braking force is required. According to the invention, means (2,4, 6,11) are provided, which reduce the reaction force supplied to the input body (22) by a certain proportion, after a certain pressure in the reaction element (7). The driver is thus given additional support and a relatively reduced increase in input force is required for a further increase in output force.

To improve its service life, the reaction plate includes a recess in the area of the abutment of a valve piston extension, in which recess a substantially incompressible, elastic insert is placed.
