Abstract (en)
[origin: EP0341595A1] The control device consists merely of a single control valve (11) with an integrated self-holding mechanism (1, 4). A time-control mechanism with throttle opening (13) is integrated in the actuating cylinder (9) of the suction valve (10), so that overall a very simple, reliable control for such vacuum drainage installations results, in which the suction valve is to be kept open for a certain length of time after the suction operation to allow the flow of air to continue. <IMAGE>
