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 web 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 the individual assemblies, with solenoid coil sub-assemblies being slipped onto stems integrally formed on the manifold. In other forms, the solenoid coils are fly wound directly on stems integrally formed with the manifold within which the operating elements of the valve assemblies are mounted. In all cases, the metal bracket functions as a mounting bracket to mount the valve-manifold module on a support surface and also functions as a common low reluctance flux return path for the magnetic circuits of all solenoids.

A carburetor having a fuel bowl, main fuel metering system means and idle fuel metering system means is shown provided with a valve assembly actuatable into either an open or closed condition; in the open position additional fuel from the fuel bowl is bypassed around the main metering restriction as to flow into the main fuel metering system means downstream of such main metering restriction and in the closed position all fuel flowing into the main fuel metering system means flows through the main metering restriction.
