Title
(EN) FUEL PUMP APPARATUS
(FR) APPAREIL DE POMPE À CARBURANT
Abstract
(EN) The present disclosure relates to a hydraulic head assembly (1) having a hydraulic head (2) and an adapter (21). The hydraulic head (2) has a first bore (5) and a pumping chamber (6). The adapter (21) has a second bore (31). The adapter (21) is connected to hydraulic head (2) such that said first and second bores (5, 31) are disposed coaxially to form a pumping element bore. A pumping element (7) is disposed within said first and second bores (5, 31) for pressurising fuel in the pumping chamber (6). A first seal (16) is formed between the pumping element (7) and the hydraulic head (2); and a second seal (17) is formed between the pumping element (7) and the adapter (21). The present disclosure also relates to a pump (P2) incorporating the hydraulic head assembly (1) described herein. The present disclosure also relates to an adapter (21) for mounting to a fuel pump (1).
(FR) La présente invention concerne un ensemble (1) tête hydraulique ayant une tête hydraulique (2) et un adaptateur (21). La tête hydraulique (2) a un premier alésage (5) et une chambre de pompage (6). L'adaptateur (21) a un second alésage (31). L'adaptateur (21) est relié à la tête hydraulique (2) de telle sorte que lesdits premier et second alésages (5, 31) sont disposés de manière coaxiale pour former un alésage d'élément de pompage. Un élément de pompage (7) est disposé dans lesdits premier et second alésages (5, 31) pour mettre sous pression le carburant dans la chambre de pompage (6). Un premier joint d'étanchéité (16) est formé entre l'élément de pompage (7) et la tête hydraulique (2) ; et un second joint d'étanchéité (17) est formé entre l'élément de pompage (7) et l'adaptateur (21). La présente invention concerne également une pompe (P2) incorporant l'ensemble (1) tête hydraulique décrit ici. La présente invention concerne également un adaptateur (21) destiné à être monté sur une pompe à carburant (P1).
