Abstract
A guide body for an electromagnetic valve device is provided. The device includes a coil assembly surrounding the guide body, a plunger driven by magnetic force and slidably disposed inside the guide body. The guide body slidably guides the plunger in an open/close direction of the valve body along a guide face thereof. The guide body includes a first nonmagnetic section that supports a pole body and a part of the plunger at which the pole body and the plunger oppose each other, a second nonmagnetic section that supports the valve body, and extends at least throughout a sliding range of the valve body, and a magnetic section intermediate the first and second sections so that a portion of the lines of magnetic force passes therethrough. The guide face is formed so as to coaxially support the plunger and the valve body displaceable in the open/close direction.
