What is indicated is a switching arrangement for pressure-actuated, especially pneumatically actuated doors or door leaves in vehicles, such as buses or the like, in which, for the purpose of the selective fixing of at least one door or door leaf (10), the closing cylinder (121) actuating the door or door leaf (10) is preceded by a regulating valve (22) which selectively shuts off or opens the closing-pressure line (14) leading to the closing cylinder (121). The regulating valve (22) is bridged, at least in its shut-off position, by a non-return valve (23), the transmitting direction of which is effective towards the closing cylinder (121). The regulating valve (22) is preferably designed as a 2/2-way solenoid valve (27). …<IMAGE>… |
