Abstract
A pressure regulator device, particularly a dome-loaded pressure regulator, regulating a blowing pressure in a blowmolding machine, including a regulator chamber. The regulator chamber includes a primary pressure port for introduction of primary medium into the regulator chamber with primary pressure, and a secondary pressure port for discharging primary medium from the regulator chamber with secondary pressure. A regulator piston is mounted displaceably inside the regulator chamber, movable into an open and a closed position by a switch position of a valve control device for controlling and/or setting the primary and/or secondary pressure. The valve control device includes a control chamber, and a sealing device arranged at a lower movement stop inside the control chamber between the secondary pressure port and the control means, such that contact of the primary medium with the control means is prevented at least partly, preferably completely, independently of the control pressure and/or primary pressure.
