Abstract
A valve is equipped with a displacement amount regulating mechanism (for example, flow rate control device). An abutment member of the displacement amount regulating mechanism protrudes inside a pilot chamber and faces an upper end surface of a valve main body portion of a valve element. When the valve element (the valve main body portion) is separated from a valve seat to bring the valve into an open state, the abutment member is brought into abutment on the upper end surface of the valve main body portion. This abutment regulates the displacement of the valve element.
