Abstract
Pompe d'injection de carburant à commande électrique pour moteurs à combustion interne, en particulier pompe d'injection combinée avec l'injecteur, comportant un piston de pompe (12) disposé et guidé dans un corps de pompe (11). Le piston de pompe (12) délimite un espace de travail (15) de la pompe et refoule, en course de refoulement, le carburant amené par une pompe d'alimentation à cet espace de travail (15) vers un injecteur tant qu'une électrovanne (26) régulatrice de débit bloque le passage du carburant qui autrement s'écoule de l'espace de travail (15) de la pompe vers une chambre basse pression (21) en passant par une conduite de dosage (25), avec une partie de corps (27) en saillie latérale sur le corps de pompe (11) au niveau du piston de pompe (12) et abritant l'électrovanne régulatrice de débit (26). La conduite de dosage (25), menant à l'espace de travail (15) de la pompe, s'étend jusque dans ladite partie de corps (27) en saillie sur laquelle sont prévus des évidements latéraux (29) dans lesquels s'insère, à la manière d'une fourchette, un manchon de fixation (28) pour la vanne régulatrice de débit (26), lequel est doté d'un filet intérieur (30) et coopère avec une douille filetée (32) dotée d'un filet extérieur (31).Electrically controlled fuel injection pump for internal combustion engines, in particular injection pump combined with the injector, comprising a pump piston (12) arranged and guided in a pump body (11). The pump piston (12) delimits a working space (15) of the pump and delivers, in the delivery stroke, the fuel supplied by a supply pump to this working space (15) towards an injector as long as one flow regulating solenoid valve (26) blocks the passage of fuel which otherwise flows from the working space (15) of the pump to a low pressure chamber (21) via a metering line (25), with a body part (27) projecting laterally from the pump body (11) at the level of the pump piston (12) and housing the flow regulating solenoid valve (26). The metering line (25), leading to the working space (15) of the pump, extends into said protruding body part (27) on which are provided lateral recesses (29) in which s' inserts, like a fork, a fastening sleeve (28) for the flow regulating valve (26), which has an internal thread (30) and cooperates with a threaded sleeve (32) provided with an external thread (31).
