摘要： A pressure adjustment device applicable in particular, but not exclusively, to stretch blow molding machines. More particularly, the invention relates to a pressure adjustment device for stretch blow molding machines of containers made of plastic material. The device includes an opening for dispensing a blowing fluid, a hollow body having a first inlet opening for a high pressure fluid and a second inlet opening for a piloting fluid. A shutter is slidably arranged within the hollow body, the shutter being held in a closed position by elastic means, wherein the adjustable opening of the shutter occurs, in contrast with the elastic means, by introducing—through said second inlet opening—the piloting fluid into a piloting chamber arranged between the hollow body the shutter, and wherein the piloting fluid has a controlled and adjustable pressure.

摘要： A blow molding apparatus for expanding plastic preforms into plastic containers may include a blow piston extending in a longitudinal direction and a blow nozzle extending from the blow piston in the longitudinal direction. The blow nozzle may be configured to apply a gaseous medium to a preform for the expansion thereof. A connection device may be structured and arranged to supply the gaseous medium to the blow molding apparatus via at least two connection lines, and a control block may be arranged between the connection device and the blow piston. The control block may be configured to control the supply of the gaseous medium during the expansion process using at least partially varying pressure levels and may have a plurality of channels for guiding the gaseous medium. The plurality of channels may be separated from each other at least in sections and may be distributed in a circumferential direction of the control block. At least two valves may be on an outer circumference of the control block. The valves may be distributed in a circumferential direction around the control block, and may be controlled independent of one another for controlling the supply of the gaseous medium to the blow nozzle. A distribution member may be configured to guide the gaseous medium into said channels. The distribution member may be arranged between the connection device and the control block if viewed in the flow direction of the gaseous medium. The channels may extend within the control block at least in sections substantially parallel to the longitudinal direction of the blow piston.

摘要： A device for molding a container from a thermoplastic material in which a heated parison is pre-blown by supplying low-pressure blowing air from a low-pressure air supply and then the blow molding is completed by subsequent supply of high-pressure blowing air and in which the high-pressure blowing air flowing out of the container that has been completely blow molded is supplied to the low-pressure air supply via a reversing mechanism during a transitional phase. A pressure monitoring is performed in the area of the low-pressure air supply and in which, after the transitional phase, the container is vented with respect to an ambient pressure whereby the pressure in the low-pressure air supply is controlled by varying the duration of the transitional phase.

The distributor block has a mixing chamber that can be directly connected to an internal space of a preform so that a combustion chamber is formed from the mixing chamber and the internal space of the preform. A feed device is provided for feeding an explosive fluid into the combustion chamber and a firing device is provided for firing the explosive fluid in the combustion chamber. Of importance is that the distributor block can be connected directly to a preform or to a formed container. The apparatus is desirably a round rotor machine with a rotatable carousel for receiving a plurality of distributor blocks having a mixing chamber that can be directly connected to an internal space of a preform. The distributor blocks are desirably arranged in such a way that they can be rotated together with the carousel. The invention also includes an apparatus, in particular a round rotor machine, for coating the inside walls of a plastic container with a barrier layer which is impermeable in relation to gases, aroma substances and the like, in which a stretch blowing mould is connected by way of a connecting portion to valve-controlled fluid lines in order to fill the container in the mould with at least one gas.

摘要： The present invention relates to a device for regulating the flow rate and/or the pressure of a fluid transferred from a high-pressure reservoir (H) to a reservoir (S). A first valve (1) provided with a control (2) is mounted in a pipe (10, 11, 12) connecting the two reservoirs (H, S). A Laval nozzle (3) located downstream of the first valve (1) is provided with an electrical pressure-drop sensor (4). A second valve (5) provided with a control (6) is connected between the downstream part of the Laval nozzle and an exhaust orifice (R). A micro-programmed system (7), designed to receive the values read by the pressure-drop sensor (4) and to drive the two controls (2, 6) of the two valves (1, 5) makes it possible to regulate the flow rate and/or the pressure of the fluid transferred from the first reservoir (H) to the second reservoir (S).
