pressdruckregelvorrichtung for a antriebszylinder of a tool or werkzeugteils is glasmaschine

摘要

The regulating device is formed as an electropneumatic or electrohydraulic pressure regulating valve (6) that is subjected to fluid pressure prevailing in the pressure fluid source (4). In the first position the fluid passage is blocked by the fluid line (3), in a second position a fluid pressure on the inlet side is further led to the working cylinder (2) so that the tool, driven by the working cylinder, or tool piece (1) does not encounter counter pressure, and in a third position its outlet side fluid pressure is regulated corresponding to a prescribed theoretical pressure as soon as the tool or tool part encounters counter pressure. Mold pressure regulating device has a pressurized fluid source (4), a fluid line (3) connecting the pressurized fluid source and the working cylinder (2), and a regulating device (6) arranged between the pressurized fluid source and the working cylinder in the fluid line and by which the pressurized fluid impingement of the working cylinder can be regulated.
