VALVE AND FLUID CONTROL DEVICE

摘要

A valve and a fluid control device are provided, the valve being suitable for the fluid control device which charges compressed air into an air reservoir and can rapidly exhaust the air from the air reservoir, requires low manufacturing costs and small power consumption, and has a small size. A check valve (102) has a first valve housing (21) and a first diaphragm (108A). The first diaphragm (108A) forms a first valve chamber (23) and a second valve chamber (26). An exhaust valve (103) has a second valve housing (31) and a second diaphragm (108B). The second diaphragm (108B) forms a third valve chamber (33) and a fourth valve chamber (36). The check valve (102) is opened and closed by a difference in pressure between the first valve chamber (23) and the second valve chamber (26). The exhaust valve (103) is opened and closed by a difference in pressure between the third valve chamber (33) and the fourth valve chamber (36).
