Abstract

L'invention concerne un circuit d'alimentation en combustible comportant une pompe d'alimentation puisant le combustible dans un réservoir et en renvoyant une partie dans celui-ci par une canalisation en by-pass partant de la chambre d'entrée d'un filtre et sur laquelle est monté un étranglement raccordé au filtre, le combustible étant également amené, à partir de la chambre de sortie du filtre, à une pompe d'injection raccordée à la canalisation en by-pass par l'intermédiaire d'une soupape de décharge. Il est caractérisé par le fait qu'un clapet anti-retour 22 est prévu sur la canalisation en by-pass, en aval de l'étranglement 6 et que, par rapport aux exécutions antérieures, tous les conduits aboutissant à une pompe d'amorçage à main associée à la pompe d'alimentation 1, ainsi que les espaces vides appartenant à cette pompe d'amorçage à main, sont réduits en volume par des pièces de remplissage de 16 à 21. Applications générales.The invention relates to a fuel supply circuit comprising a supply pump drawing fuel from a tank and returning a part to the latter through a by-pass pipe leaving the inlet chamber of a filter. and on which is mounted a throttle connected to the filter, the fuel being also supplied, from the outlet chamber of the filter, to an injection pump connected to the bypass line via a relief valve. dump. It is characterized by the fact that a non-return valve 22 is provided on the by-pass pipe, downstream of the throttle 6 and that, compared to previous executions, all the pipes leading to a priming pump hand associated with the feed pump 1, as well as the empty spaces belonging to this hand priming pump, are reduced in volume by filling parts from 16 to 21. General applications.
