<p>The disclosure relates to a pneumatic pressure regulator for pressure adjustment of a regulating pressure in a pressure chamber with a regulator membrane which is held in force equilibrium by a regulator spring and the regulating pressure, wherein the regulator membrane is coupled with a control valve in such a way that the control valve opens or closes in dependence upon the actual regulating pressure. For increasing the stability and the constancy of the regulating pressure it is proposed to form the control valve by a dimensionally stable ball which is seated in a loaded manner by means of a spring in a conical bore which tapers in the direction of the regulator membrane and is in a housing wall which lies opposite the regulator membrane with regard to the pressure chamber, the regulator membrane having a reinforcement in the contact region with the ball, and the ball following the movement of the regulator membrane in its normal direction.</p> |
