Abstract

Selon l'invention, l'évidement en forme de trou borgne 4 est relié à un espace 8 commençant directement sous le siège 3; tous les trous d'injection 6, 7, 10 débouchent dans l'évidement 4; et, à chaque ou presque chaque position de l'aiguille 2, les sections de la fente du siège et de l'espace 8 sont plus grandes que la section du ou des trous d'injection 6, 7, 10 libérés selon le cas par le téton 5. L'invention est applicable en particulier aux moteurs à explosion à compression d'air.
