Title
(EN) COMBINED GAS AND LIQUID PUMP
(FR) POMPE COMBINÉE POUR GAZ ET LIQUIDES
Abstract
(EN)
The present invention provides a combined gas and liquid pump (46) for an internal combustion engine (10). The pump (46) includes a casing (58) having a cavity (60) containing a rotor (62) and a vane (64) slidably mounted to the rotor (62), wherein the cavity (60) is provided with an inlet (50) connectable to a gas source, a further inlet (48) connectable to a liquid source which is separate to the gas source, and an outlet (56). The rotor (62) and vane (64) are movable to draw liquid and gas into the cavity (60) through the respective inlets (50,48) and to move said liquid and gas out of the cavity (60) through the outlet (56). The inlets (50,48) are arranged through the casing (58) such that fluid is drawn first through one of the inlets and then through the other of the inlets before being discharged through the outlet (56).
(FR)
La présente invention concerne une pompe combinée (46) pour gaz et liquides destinée à un moteur (10) à combustion interne. La pompe (46) comprend un carter (58) présentant une cavité (60) contenant un rotor (62) et une ailette (64) montée de façon coulissante sur le rotor (62), la cavité (60) étant munie d'une entrée (50) susceptible d'être reliée à une source de gaz, d'une autre entrée (48) susceptible d'être reliée à une source de liquide distincte de la source de gaz, et d'une sortie (56). Le rotor (62) et l'ailette (64) sont mobiles afin d'aspirer du liquide et du gaz dans la cavité (60) par les entrées respectives (50,48) et de chasser ledit liquide et ledit gaz de la cavité (60) par la sortie (56). Les entrées (50,48) sont pratiquées à travers le carter (58) de telle sorte que du fluide soit d'abord aspiré à travers l'une des entrées, puis à travers l'autre entrée avant d'être refoulé par la sortie (56).
