  • the first emergency valve 42 is z. B. designed as manually operable against a spring force 2/2-way valve. When operated manually, the first emergency actuation valve 42 causes a venting of the self-holding pressure medium branch 40.
  • the pressure medium flowing via the throttle 33 can not maintain any pressure required for maintaining the operating position of the emergency control valve 34, so that the emergency control valve 34 is switched to the emergency position by spring force.
  • the door actuation valve device 1 also has a second pressure medium connection 4 for a second emergency actuation valve 41.
  • the second emergency actuation valve 41 may be constructed, for example, comparable to the first emergency actuation valve 42.
  • the second pressure medium connection 4 can be blocked or throttled with respect to the first pressure medium connection 5 or with respect to the self-holding pressure medium branch 40.
  • This is a Shut-off valve 31 is provided, the one in the FIG. 1 has assumed (unthrottled) passage position and a blocking or throttle position.
  • the check valve 31 is formed in the embodiment with a throttle position. In this case, the check valve 31 has a throttle 32.
  • the check valve 31 is designed as a pressure medium-controllable 2/2-way valve.
  • a pressure medium control input of the check valve 31 is connected to the closing control valve 20.
  • the check valve 31 Upon actuation of the closing control valve 20 as a result of an electrical signal from an electronic control device, the check valve 31 is brought by the pressure supplied by the closing control valve 20 in the throttle position in which the throttle 32 is effective and the second pressure medium connection 4 with respect to the first pressure medium connection 5 throttles.
  • a user via the second emergency valve 41, which may be located eg inside the vehicle, with unconfirmed check valve, ie ineffective throttle 32, in the same way as with the first emergency valve venting of the self-holding pressure medium branch 40 and thus a Trigger the emergency position.
  • check valve 31 and thus effective throttle 32 is vented to the second pressure medium connection 4 upon actuation of the second Notbetusch Incsventils due to the throttle 32 only with a relatively low pressure fluid flow. During this, pressure medium can flow from the pressure medium supply via the throttle 33.
  • venting ports 3 are each connected to the atmosphere.
  • the door actuating valve device 1 may have in its valve housing a central ventilation, with which the individual venting ports 3 are connected.
  • pressure switches 43, 44, 45 are also shown, which generate pressure-dependent electrical signals.
  • the electrical signals are supplied to the electronic control device, which uses the signals for plausibility and safety testing of the vehicle door system.
