Abstract:

PROBLEM TO BE SOLVED: To provide a fluid connector which reduces a force necessary for holding a corresponding flow passage member.SOLUTION: This fluid connector 10 fluidly connects an outside fluid supply source and a pressure sensor 22. A flow passage connecting member 14 is arranged in a first passage 24 of a cylindrical main body member 12, and a valve member 16 is arranged in a second flow passage 40 of the flow passage connecting member 14. When relative pressure at an inlet opening 34 side with respect to pressure at an outlet opening 38 side of the second passage 40 reaches a constant magnitude or higher, the valve member 16 is displaced against an energization force of a coil spring 64, and takes an opening position for opening the second passage 40. The flow passage connecting member 14 receives a force to the pressure sensor 22 side by the relative pressure, and an abutment face 44 of a nozzle part 42 is pressed against a tip face 68 of the pressure sensor 22. By this constitution, the abutment face 44 and the tip face 68 are sealed and engaged with each other by a metal seal.SELECTED DRAWING: Figure 3
