VALVE FOR CONTROLLING BRANCH LINE

摘要

PURPOSE: To perfectly function and eliminate dead space in respect to a valve which controls a branch line branching from a main line in a valve chamber arranged in a valve housing. CONSTITUTION: In order to avoid dead space in a valve for control of a branch line, a valve chamber 4 contains an elastomer part 7 provided with a main channel 8 and a branch channel 9 branching from it. Both ends of the main channel 8 are sealingly connected with the main lines. The free end of the branch channel 9 is sealingly connected with the branch line 9'. A valve lifter 11 is arranged in a valve housing 1. The valve lifter acts on the branch channel 9 in the branch-off area directly immediately near the elastomer member 7 and directly adjacent to an abutting portion 13 of the valve housing 1, so as to reduce a width of cross-section of the branch channel 9.
