Abstract
PURPOSE:To obtain a valve with a simple structure, having no sliding part and which can securely switch over flow passage by supporting both ends of a valve stem with diaphragm and keeping the value stem in a noncontact condition with a valve bore. CONSTITUTION:A valve bore 14 is provided in a center housing 12 and a normal-use port 16 and alternative ports 17, 18 are opened in, while being perpendicular to, the valve bore 14. And, the peripheral edge part of the diaphragms 31, 32 are fixed in between the center housing 12 and the both right and left side housings 13, 13 re respectively. Also, both ends of a valve stem 25 are fixed to each center part of the diaphragms 31, 32. A valve body 26 formed with an elastic material is fitted on the center part of the valve stem 25 and annular projections 26a, 26b are formed opposite to valve seats 23, 24 on the valve body 26. In this structure, the valve stem 25 is moved by means of an plunger 42 to switch over the normal-use port 16 to either of the alternative ports 17, 18.
