Abstract
A stopper formed of a magnetic material and forming a portion of a magnetic circuit has a deformable portion that deforms in accordance with the pressure in a space within a sleeve. The deformable portion is provided with a pressure sensor that measures the amount of deformation of the deformable portion. The deformable portion, corresponding to a diaphragm, is formed in the stopper, which is a conventional electromagnetic valve component part. Therefore, it is no longer necessary to provide a diaphragm or a seal member.
