Abstract
A valve operating mechanism comprises a valve having a valve member and a valve seat, the valve seat having a fluid passage hole is arranged at an end of a fluid chamber containing fluid such as liquid or gas, the valve member which is axially moved relative to the valve seat, to thereby control the passage of fluid, an axially movable member spaced a certain distance from the valve seat, radially displaceable members such as thread-shaped members, linear members or bar-shaped members through which the axially movable member is interconnected with a rear part of the body, and means for causing, when a grasping force is applied to the radially displaceable members the valve seat moves relative to the valve member, thus opening the valve, and for causing, when the grasping force is eliminated, the valve seat comes into abutment against the valve member, thus closing the valve.
