Patent ID: 7744066

Claim:
A carburetor, comprising: an air inlet with a mechanically adjustable air valve; a mechanically adjustable atomiser discharging in the air inlet; fuel pressure regulating means connected to a fuel valve for regulating a fuel pressure of fuel injected in the air inlet and connected to a vacuum sensing conduit discharging into the air inlet; and a mechanical metering device coupled with the air valve and the atomiser, the metering device including a multipartite spindle having a plurality of spindle parts which are mutually rotatable, wherein the air valve is pivotable around one spindle part, and the multipartite spindle includes a fuel conduit leading to the atomiser such that an amount of fuel running through the fuel conduit to the atomiser is controllable by rotating the one spindle part, in proportion with an amount of air allowed to pass, relative to an other spindle part for maintaining a stoichiometric ratio between amounts of air and fuel.
