Abstract

A metering device for a fuel control system includes a block having a pair of parallel transverse bores which are interconnected to a pair of parallel longitudinal bores so as to provide a plurality of passageways in which appropriate valves may be placed.

Claims

1. A metering device, in combination therewith, a fuel control system for use in a vehicle having a fuel line for supplying fuel to a carburetor, said metering device comprising a mounting block, a first pair of passageways extending into said block and exposed at one face of said block, said passageways terminating in closed ends within said block, a second pair of passageways extending into said block and intersecting said first pair of passageways, a main meter valve in one of said second pair of passageways with one of said pair of passageways being exposed from said block to comprise an outlet passageway, one of said first pair of passageways comprising an inlet passageway and the other of said first pair of passageways comprising a by-pass passageway, the other of said second pair of passageways comprising a by-pass branch interconnecting said inlet passageway and said by-pass passageway, a by-pass valve in said by-pass passageway for selectively closing flow communication between said inlet passageway and said by-pass passageway, an upstream portion of said fuel line being connected in flow communication with said inlet passageway, and a downstream portion of said fuelline connected in flow communication with said outlet passageway.

2. The device of claim 1 wherein said first pair of passageways are parallel transverse bores, and said second pair of passageways being parallel longitudinal bores.

3. The device of claim 2 including mounting brackets mounted to said block.

4. The device of claim 3 wherein said main valve is a needle valve, and said by-pass valve being a solenoid valve.

5. The device of claim 4 including a first nipple connected to said block communicating with said inlet passageway, and a second nipple connected to said block communicating with said outlet passageway.
