Title (EN) ELECTRIC COOLANT PUMP
(FR) POMPE À LIQUIDE DE REFROIDISSEMENT ÉLECTRIQUE
(DE) ELEKTRISCHE KÜHLMITTELPUMPE
Abstract:
(EN) The invention relates to an electric coolant pump (1) comprising a pressure-controlled valve device (6) arranged on an outlet side, said device comprising a coolant inlet (3), a first coolant outlet (4) and a second coolant outlet (5). The valve device (6) is designed to, in accordance with the selected operating point of the coolant pump (1) and the pressure (p) in a coolant (2), open and close at least the first and/or the second coolant outlet (4, 5) or to open simultaneously at least the first and second coolant outlets (4, 5).
(FR) La présente invention concerne une pompe à liquide de refroidissement électrique (1) comprenant un dispositif de soupape (6) commandé par pression et disposé côté sortie, lequel dispositif comprend une entrée de liquide de refroidissement (3), une première sortie de liquide de refroidissement (4) et une seconde sortie de liquide de refroidissement (5), le dispositif de soupape (6) étant conçu de sorte qu’en fonction du point de fonctionnement sélectionné de la pompe à liquide de refroidissement (1) et ainsi de la pression (p) dans le liquide de refroidissement (2), il ouvre ou ferme au moins la première et/ou la seconde sortie de liquide de refroidissement (4, 5) ou ouvre simultanément au moins la première et la seconde sortie de liquide de refroidissement (4, 5).
(DE) Die vorliegende Erfindung betrifft eine elektrische Kühlmittelpumpe (1) mit einer auslassseitig und druckgesteuerten Ventileinrichtung (6) mit einem Kühlmitteleingang (3), einem ersten Kühlmittelausgang (4) und einem zweiten Kühlmittelausgang (5),wobei die Ventileinrichtung (6) derart ausgebildet ist, dass sie in Abhängigkeit des gewählten Betriebspunkts der Kühlmittelpumpe (1) und damit des Drucks (p) in einem Kühlmittel (2) zumindest den ersten und/oder zweiten Kühlmittelausgang (4, 5) öffnet oder schließt oder zumindest den ersten und zweiten Kühlmittelausgang (4, 5) gleichzeitig öffnet.
