ABSTRACT:
A valve device for a vacuum brake booster in which the poppet valve arranged in the bore of the control housing is held by means of a supporting ring provided with a radially inwardly extending flange. The flange holds a tubular part serving to hold and support of the valve spring which, on one end rests on the rear annular surface of the valve flange of the poppet valve and which, on the other side is supported on a collar of the piston rod. The valve spring has a cylindrical spring section and a conically shaped spring section, the length of the cylindrical section approximately corresponding to the length of the tubular part of the supporting ring.
