Monobloc fuel flow counter and filter for motor vehicle - contains by-pass for filter and degassing chamber for excess fuel returned from injector with gas exhaust controlled by float

Fuel from a tank enters an inlet to a filter and flows via an non-return valve to a counter. A bypass channel containing an non-return valve allows fuel to flow to the counter directly from the inlet. The counter comprises a magnetic index driving a magnetic follower from which an analogue or digita...

Beschreibung
Zusammenfassung:Fuel from a tank enters an inlet to a filter and flows via an non-return valve to a counter. A bypass channel containing an non-return valve allows fuel to flow to the counter directly from the inlet. The counter comprises a magnetic index driving a magnetic follower from which an analogue or digital display of total flow can be displayed on the vehicle instrument panel. The counter outlet supplies the injection pump for a diesel engine. A return flow inlet from the injector feeds a degassing chamber (4) with a gas exhaust controlled by a float operated valve in a swan neck pipe. Fuel from this chamber flows via a pressure control valve to the injector pump circuit. L'invention concerne un dispositif monobloc combiné de comptage et filtrage d'un liquide et un dispositif de filtrage. Un corps 1 comprenant un compteur 3 de gazole pour moteur Diesel est raccordé à une arrivée de réservoir à travers un filtre 2 dont la sortie est dirigée sur le compteur 3 à travers un canal 29. Un by-pass 24 comprenant un clapet taré 25, 26, 27 permet de court-circuiter automatiquement le filtre 2, mais pas le compteur, pour un degré de colmatage choisi. Une cuve de dégazage à niveau minimum est incorporée dans le dispositif et débouche en aval 33 du compteur 3. (CF DESSIN DANS BOPI)
