Abstract

This repriming system according to the invention comprises a pump 1, a discharge valve 4, at least three T couplings 2 and at least one nonreturn valve 3 and at least one pipe 5. The system according to the invention, owing to the combined action of its components, is particularly designed for repriming and automatically purging a feed circuit for any type of diesel engine.

Description

La présente invention concerne un dispositif destiné à réamorcer et à purger automatiquement le circuit d'alimentation de tout type diesel.The present invention relates to a device intended to automatically prime and purge the supply circuit of any diesel type.

Le dispositif selon l'invention permet de remédier immédiatement au phénomene de désamorçage de la pompe à injection du moteurtdiesel. The device according to the invention makes it possible to immediately remedy the phenomenon of defusing the injection pump of the diesel engine.

Il facilite le démarrage à froid grâce à la surcharge d'alimentation qu'il apporte.It facilitates cold starting thanks to the supply overload it brings.

Il permet également la purge automatique du circuit d'alimentation de gasoil, lors d'un remplacement du filtre à gasoil (11).It also allows automatic bleeding of the diesel supply circuit, when the diesel filter (11) is replaced.

L'invention sera mieux comprise à partir des dessins annexés où:
La figure 1 représente le dispositif de base.The invention will be better understood from the appended drawings where:
Figure 1 shows the basic device.

La figure 2 représente le montage du dispositif.Figure 2 shows the mounting of the device.

Le dispositif selon l'invention comporte une pompe (1) d'alimentation 12 ou 24 volts, qui fonctionne par aspiration de gasoil en provenance du réservoir (6) par l'orifice (12) et qui le refoule en (13) en direction du clapet antiretour (3).The device according to the invention comprises a 12 or 24 volt supply pump (1), which operates by suction of diesel fuel from the tank (6) through the orifice (12) and which discharges it in (13) in the direction the non-return valve (3).

Le clapet antiretour (3) posé sur la canalisation d'arrivée de gasoil (9) assure le fonctionnement du dispositif et assure le circuit normal moteur tournant.The non-return valve (3) placed on the diesel supply line (9) ensures the operation of the device and ensures the normal circuit with the engine running.

Le dispositif comporte des raccords en T (2a) qui permettent la déviation du carburant en 12, 13, vers la pompe (1).The device comprises T-connectors (2a) which allow the fuel 12, 13 to be diverted towards the pump (1).

La sécurité du dispositif est assurée par le clapet de décharge (4) qui s'installe sur la pompe à injection (8), celui ci évite que l'air ne passe dans la pompe (8) et renvoie l'air dans le réservoir (6), régulant ainsi la pression, quant au raccord en T (2b) celuici permet la purge automatique de la pompe (8) par le clapet de décharge (4).The safety of the device is ensured by the relief valve (4) which is installed on the injection pump (8), this prevents air from passing into the pump (8) and returns the air to the tank. (6), thus regulating the pressure, as for the T-connector (2b), this allows the automatic purging of the pump (8) by the relief valve (4).

Le dispositif selon l'invention est particulièrement destiné aux moteurs diesels. Ce dispositif remédie au désamorçage de la pompe à injection sur moteur diesel, tel que sur les bateaux voguant en haute mer, le désamorçage est fréquent et le réamorçage est long.The device according to the invention is particularly intended for diesel engines. This device remedies the defusing of the injection pump on a diesel engine, such as on boats sailing on the high seas, defusing is frequent and re-priming is long.

Ce dispositif permet également la purge automatique du circuit d'alimentation de gasoil lors du remplacement du filtre à gasoil. This device also allows the automatic bleeding of the diesel supply circuit when replacing the diesel filter.
