    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.

    Abstract: An apparatus for shaping plastics material pre-forms into plastics material containers has a movable carrier on which are arranged a plurality of shaping stations for shaping the plastics material pre-forms into the plastics material containers. Each shaping station has a stressing device which acts upon the plastics material pre-forms for the expansion thereof with a gaseous medium, and a pressure preparation device which prepares the gaseous medium. The pressure preparation device is arranged in a stationary manner and supplies the shaping stations with the gaseous medium for the expansion of the plastics material pre-forms by way of at least one connection line. A distribution device is provided which distributes the gaseous medium from the pressure preparation device shaping stations. A control air line supplies the valve device with a control gas, and a blowing air line supplies the shaping stations with the gaseous medium, are separate from each other at least downstream of the distribution device in a flow direction of the gaseous medium.

    Abstract translation: 用于将塑料材料成形为塑料材料容器的成型装置具有可移动的载体,在该载体上布置有用于将塑料材料预成型塑塑成塑料材料容器的多个成形工位。 每个成形工位都具有一个应力装置,其作用于用气体介质膨胀的预塑料的塑料材料,以及制备气体介质的压力调节装置。 压力调节装置以静止的方式布置,并且通过至少一条连接管线向成形站供应气态介质以用于膨胀塑料材料预成型件。 提供一种分配装置,其从压力准备装置成形站分配气态介质。 控制空气管路为阀装置提供控制气体,并且吹送空气管线向成形站供应气态介质,在气体介质的流动方向上至少在分配装置的下游彼此分离。
