Abstract:
PCT No. PCT/EP89/00045 Sec. 371 Date Aug. 31, 1989 Sec. 102(e) Date Aug. 31, 1989 PCT Filed Jan. 17, 1989 PCT Pub. No. WO89/06764 PCT Pub. Date Jul. 27, 1989.The invention relates to a process for controlling the medium inlet into at least one leakage cavity of a valve according to the opening part of claim 1. When applying the proposed process to a polyway-switching valve, the construction of which is novel per se, a valve is created which is novel with view to the switching function and with view to its properties, in particular the leak-proof property of each individual seat region. In the procedural technique this is inter alia achieved in that in the valve position deviating from the normal position there is provided at each switched valve seat a substitution of the closing member or shutter element by the respective other one for shutting off the leakage cavity from the inner space.
