Unit consisting of electromagnetic valves

摘要

A unit comprises a valve housing having a bottom portion; and a plurality of electromagnetic valves standing on the bottom of the valve housing. Each electromagnetic valve includes a coil which is housed in a housing structure. A cover member is put on head portions of the electromagnetic valves. A bolt extends from the cover member to the bottom portion of the valve housing to bias the cover member toward the bottom portion of the valve housing thereby to tightly fix the electromagnetic valves to the valve housing. A printed-circuit board is positioned above the cover member. Bracket portions for supporting the printed circuit board extend upward from the housing structure toward the printed-circuit board while keeping away from a lateral end of the cover member. Conductive lines are embedded in each bracket portion to provide an electric connection between each coil and the circuit of the printed-circuit board.
