In order to avoid dead volumes in a valve for control of a branch line departing from the main line in a valve chamber located in a valve housing, the valve chamber contains an elastomer part provided with a main channel and a branch channel departing from it, and the two ends of the main channel are sealingly connected with the main lines. The free end of the branch channel is sealingly connected with the branch line, and further that a valve lifter be provided in the valve housing, which acts on the branch channel in the branch-off area directly adjacent to the main channel of the elastomer part, thus reducing the cross-section of the branch channel, which is held in place by a counterpiece in the valve housing.
Valve for control of a branch line extending from a main line in a valve chamber located in a valve housing, wherein an elastomer part is provided with a main channel and a branch channel extending therefrom, said main channel and said branch channel lying in a common plane, opposing ends of said main channel being sealingly connected with said main line, and a free end of said branch channel being sealingly connected with said branch line, a valve lifter provided in said valve housing, said branch channel bearing against a counterpiece in said valve housing, said valve lifter acting on said branch channel toward said counterpiece in a direction perpendicular to said plane and in an area directly adjacent said main channel of said elastomer part for reducing the size of said branch channel.
