Title
(EN) A HOUSING FOR A FUEL CONTROL UNIT OF A HIGH PRESSURE PUMP
(FR) LOGEMENT POUR UNE UNITÉ DE COMMANDE DE CARBURANT D'UNE POMPE À HAUTE PRESSION
Abstract
(EN)
Disclosed herein is a housing (200) for a fuel control unit of a high pressure pump. The housing (200) comprises a first connector (202) in flow communication with an overflow valve (204) located within the housing (200). The overflow valve (204) opens into a second connector (206), and a third connector (208) in flow communication with the first connector (202) via a metering unit (210) located in the housing (200). The housing (200) is made from plastic and the first connector (202), the second connector (206) and the third connector (208) are integrated with the housing (200).

La présente invention concerne un logement (200) pour une unité de commande de carburant d'une pompe à haute pression. Le logement (200) comprend un premier raccord (202) en communication fluidique avec une soupape de trop-plein (204) située à l'intérieur du logement (200). La soupape de trop-plein (204) s'ouvre dans un deuxième raccord (206), et un troisième raccord (208) est en communication fluidique avec le premier raccord (202) par l'intermédiaire d'une unité de dosage (210) située dans le logement (200). Le logement (200) est constitué de plastique, et le premier raccord (202), le deuxième raccord (206) et le troisième raccord (208) sont intégrés au logement (200).
