Abstract
The present invention provides a channel housing comprising curving channels whereby complex and varied channels can be compactly contained. Plural curving channels that must be connected to plural valves, for example, are formed by partitioning walls forming curving channels inside a pair of symmetrical housing halves, which are then bonded together to form the complex channel system. The housing halves may be joined by welding or adhesive bonding. To improve the bonding strength, a pair of opposing channel members is provided along the length of the contacting members that are welded or bonded. The cavity formed by the opposing channel members D, D is then filled with an adhesive resin M to integrate the two halves.
