Abstract
Various forms of control modules incorporating multiple solenoid actuated valves and passages are disclosed. All disclosed modules include a one piece sheet metal mounting bracket upon which the multiple valves and a manifold may be assembled in a frictional snap fit assembly procedure. The one piece sheet metal mounting bracket is formed with a pair of spaced parallel vertical webs at least, one being formed with a double thickness of the sheet metal material and provided with U-shaped recesses extending into the web from its upper edge. The U-shaped recesses are adapted to snugly receive a portion of each valve housing which is formed with a pair of spaced radially outwardly projecting flanges which frictionally grip the opposed sides of the doubled web to hold the valve assemblies in a seated position. The other web engages the rearward ends of each valve assembly. Several variant assembly techniques are disclosed. In some cases, self-contained solenoid valve assemblies are assembled in plug-in fashion to a one-piece manifold and held in assembled relationship to the manifold by the webs of the sheet metal bracket. In other forms, a one-piece manifold incorporates portions of th…
