Document Type and Number:
Japanese Patent JP6900076
Kind Code:
B2
Abstract:
To provide a flow channel change-over valve capable of eliminating a seal member such as O-ring for preventing leakage among a plurality of outlets, not requiring any severe size management or high-precision processing forming technology, capable of positively preventing leakage among the outlets and further restricting a processing and assembling cost or product cost.SOLUTION: A valve body 40 is integrally arranged at the lower end part of a valve shaft 30. The valve body 40 has at least one of opening passages 41, 42 selectively opening an inlet 20 and each of outlets 21, 22. The upper surface of the valve body 40 is pushed against valve seats 15A, 15B with fluid pressure in a valve main body 6. Under this state, a valve shaft 30 with the valve body 40 is turned to selectively take any one of a first flowing state in which fluid flows from the inlet 20 to the outlet 21 through the opening passage 41 and a second flowing state in which fluid flows from the inlet 20 to the outlet 22 through the opening passage 42.SELECTED DRAWING: Figure 7
