Abstract (en)
[origin: EP1016783A2] The device incorporates a control chamber (24) with drainage channel having a section (29), which contains an intermediate valve with valve member (57). A connection channel (69) with a first connection profile (70) is provided between valve chamber and control chamber. The intermediate valve member is moved from its closed position towards the control chamber and against a closing force, by the head of the closing valve member (34). This creates a second connection profile between valve chamber (30) and control chamber, which is larger than the first one.
