Abstract

Es wird eine Ventileinrichtung angegeben, bei der mit sehr geringem Aufwand und ohne Verwendung zusätzlicher Steueranschlüsse an der Ventileinrichtung das durch die Ventileinrichtung strömende Druckmittel wenigstens zeitweise gedrosselt hindurchströmen kann, so daß die Bewegung einer durch das Druckmittel betätigten Tür beim Öffnen und Schließen in der Nähe der jeweiligen Endlagen gedämpft werden kann.A valve device is specified in which with very little effort and without using additional Control connections on the valve device that flowing through the valve device Flow throttled through at least temporarily can, so that the movement of one through the pressure operated door when opening and Steamed close to the respective end positions can be.

Die Ventileinrichtung (9) weist Druckmittelanschlüsse (1, 2, 40, 50) und Steueranschlüsse (11, 21, 31), die mit einem elektronischen Steuergerät (60) verbunden werden können, auf. Zur Drosselung des Druckluftstromes weist die Ventileinrichtung (9) neben einem ersten Durchlaßquerschnitt (3) noch einen zweiten Durchlaßquerschnitt (4) und ein Umschaltventil (5) zur Umschaltung zwischen diesen Durchlaßquerschnitten (3, 4) auf. Das Umschaltventil (5) ist druckmittelbetätigbar und kann mit einem durch Steuersignale an den Steueranschlüssen (11, 21, 31) bewirkten Steuerdruck beaufschlagt werden.The valve device (9) has pressure medium connections (1, 2, 40, 50) and control connections (11, 21, 31) with an electronic control unit (60) can be connected. For throttling of the compressed air flow has the valve device (9) next to a first passage cross section (3) a second passage cross section (4) and a Switch valve (5) for switching between them Passage cross sections (3, 4). The changeover valve (5) can be operated with pressure fluid and can be operated with a through control signals at the control connections (11, 21, 31) effected control pressure become.

Die Ventileinrichtung (9) wird vorzugsweise in einer pneumatischen Türsteueranlage in einem Omnibus eingesetzt. Die Ventileinrichtung (9) ist elektrisch mit einem elektronischen Steuergerät (60) und pneumatisch mit einem Druckluftvorratsbehälter (70) sowie einem mechanisch mit der Tür verbundenen Stellzylinder (80) verbunden.

Figure 00000001
The valve device (9) is preferably used in a pneumatic door control system in a bus. The valve device (9) is electrically connected to an electronic control unit (60) and pneumatically to a compressed air reservoir (70) and an actuating cylinder (80) mechanically connected to the door.
