Abstract
Provided are a decompression shut-off valve device having high responsiveness and a method for controlling the same. The decompression shut-off valve deviceincludes an on-off valve, a detection pin, and an interlocking memberwhich operates the on-off valveby displacement of the pressure-receiving section, a valve chamber, an accommodating chamber, and a cylinderwhich accommodates an enlarged diameter sectionprovided in a rod sectionof the on-off valve. The rod sectionis slidably held through a second partition wall, and a rod end portionof the rod sectionis connected to the detection pinvia the interlocking member. The cylinderis partitioned into a small diameter low-pressure chamber, and a large diameter high-pressure chamberin which the working fluid having a higher pressure than the low-pressure chamberis accommodated.
