An electromagnetic valve having a flow passage opened and closed by the drive of an electromagnet. The electromagnetic opertor includes a casing, an electromagnetic coil, a plunger adapted to be driven by the electromagnetic coil, a sleeve for guiding the plunger, a yoke fitted around the sleeve and formed with an axially extending central portion and a notch in its outer circumference, and a push rod fixed to the plunger. The valve portion includes an outer valve body, having an input port and a discharge port, which is fixed to the casing of the electromagnet with a flange fitted over and mating with the raised central portion of the yoke. An inner valve body is mounted in the outer base and has an axial bore for receiving the push rod. A ball is interposed between the outer valve body and the inner valve body for opening or closing the passage of the valve, extending from the input port to the discharge port, by the drive of the push rod.

A two-way electromagnet has an input port and a discharge port at opposing ends of a flow passage which is opened or closed by the drive of an electromagnet. The two-way electromagnetic valve operating portion or module includes an electromagnetic coil, a plunger adapted to be driven by the electromagnetic coil, a yoke fitted around a sleeve and a push rod fixed in the plunger. The valve portion or module includes an outer valve body in which the input port and a valve seat are formed, an inner valve body formed with a bore for receiving the leading end of the push rod therethrough and a passage communicating with the discharge port. The valve member is a ball arranged between the valve seat of the outer valve body and the inner valve body. The push rod is moved forward when the electromagnetic coil is deenergized to bring the ball into abutment against the valve seat to thereby close the input port. When the electromagnetic coil is energized, the push rod is moved backward to allow the ball to move out of the valve seat thereby opening the input port and establishing communication between the input port and the discharge port. Alternatively, the valve seat may be formed in the inner valve body.

An optical member inspection apparatus includes an inspection optical system having a light source, and a diffusing means for diffusing the light emitted from the light source. The diffusing means has a central portion and a peripheral portion. The diffusion transmittance of the peripheral portion is higher than the diffusion transmittance of the central portion. The inspection optical system is also provided with an image pick-up means to pick-up an image of the optical member to be inspected, and is positioned so as to receive that light emitted from the light source and transmitted through the diffusing means and the optical member. A judging means is also provided, for judging whether or not the optical member has a defect, in accordance with image signals output from the image pick-up means.

A fuel inlet comprises an inlet pipe, a breather tube, a retainer, a spiral groove, and the like. The inlet pipe is formed by processing a metal pipe and has an expanded portion, a taper portion, and a main body in the order from the fuel port. The expanded portion is formed by increasing the diameter by bulging. In order to prevent defects in the pipe such as cracks from being caused during bulging, SUS304, SUS304L, or SUS436 according to JIS is used as the material of the pipe. The diameter of the main body is 25.4 mm and the diameter of the expanded portion is 50 mm. A spiral groove on which a screw-type fuel port cap can be screwed is formed in the vicinity of the open end of the expanded portion, by crimping the inlet pipe and the retainer together. On the outer surface of the expanded portion in the vicinity of the open end is provided an outer-cylinder-like flange formed integrally with the inlet pipe.
