Abstract

A fuel supply unit ( 1 ) is provided e.g. a carburetor or a low pressure injection system of an internal combustion engine. The fuel supply unit ( 1 ) includes a main air passage ( 3 ), which has a throttle valve ( 8, 9 ) mounted therein and the throttle valve ( 8, 9 ) includes a throttle shaft ( 8 ) extending between two to one another opposite located shaft sides ( 6, 7 ). A control module ( 2 ) for the fuel supply ( 2 ) is mounted to one ( 7 ) of the shaft sides ( 6, 7 ), which control module ( 2 ) includes throttle position detecting means ( 30; 300 ) for monitoring the position of the throttle valve ( 8, 9 ), and fuel valve means ( 60 ) for controlling the fuel supply to the main air passage ( 3 ). Also, an ignition system is provided which is able to control the ignition timing with respect to status of the at least one of the means ( 30; 300, 40, 60, 100 ) in the control module ( 2 ) in order to at least control the idle speed of the engine. The ignition system further being arranged to power at least one of the means ( 30; 300, 40, 60, 100 ) of the control module ( 2 ).

First claim

The invention claimed is:

1. An electrically operated fluid valve for controlling a fluid flow in a fluid passage in a fuel supply unit of an internal combustion engine, the fluid valve comprising:
an axially movable plunger including a permanent magnet having its magnetic direction axially oriented providing a front pole and a real pole;
an axially extending chamber with two opposite located valve seats limiting the axial movement of the plunger, a front valve seat facing the f…
