ABSTRACT:
An apparatus for injecting pulverulent fuel into the combustion chamber of internal combustion engines includes a pre-chamber for the fuel powder which is to be supplied to the combustion chamber during an engine cycle. This pre-chamber is adapted, during an engine cycle, to be successively connected to a vacuum source, a fuel supply and the combustion chamber. To this end, the apparatus includes a movable member having the pre-chamber formed therein and being adapted, by co-operation with sealing elements applied under pressure against the movable member, sealingly to engage fixed connections leading to the vacuum source, the fuel supply and the combustion chamber. During the operating cycle of the movable member the pre-chamber successively passes the aforementioned connections so as to be placed in communication with the vacuum source, the fuel supply and the combustion chamber.
