Abstract:
1. A multiple manifold valve comprising; a multiple valve mounted on a manifold base, and a top cover configured to cover the multiple valve in a sealed state, wherein the multiple valve comprises a plurality of electromagnetic valves; the top cover is integral and covers the entire multiple valve mounted on the manifold base and is comprises a transparent or translucent synthetic resin; a plurality of positioning pins formed on the lower ends of peripheral walls of the top cover in a discrete state; the top cover being positioned by inserting the positioning pins into each of small holes in the manifold base; and the top cover being screwed into the manifold base at a plurality of spots including at least the four corners; a reinforcing rib formed on an inner face of a top plate of the top cover, the rib being brought into contact with the upper faces of the electromagnetic valves mounted on the manifold base so as to extend along parallel end portions of two adjacent electromagnetic valves in a straddling state on one end portion and the other end portion of the parallel end portions or the rib being arranged so as to extend along parallel end portions of two adjacent electromagnetic valves and in a straddling state on one end portion and the other end portion of the parallel end portions in a state in which such a positional relationship is maintained that the rib is brought into contact with the electromagnetic valves within a range where the top cover is elastically deformed by a pressing force from the outside acting on the top cover; and only one rib is brought into contact with each pair of electromagnetic valves by arranging one rib for every other pair of adjacent electromagnetic valves.
