<P>PROBLEM TO BE SOLVED: To provide a vehicular oil supply device with a mechanical oil pump and a motor driven oil pump, for preventing a rising delay of hydraulic pressure in starting an engine or the occurrence of air sucking abnormal sounds in the motor driven oil pump, as a result of the entry of air into the mechanical oil pump during stopping the engine. <P>SOLUTION: A communication passage 90 is provided for introducing oil from a lubricating/cooling oil path 86 into the suction side of the mechanical oil pump 54. With the operation of the motor driven oil pump 58, the oil is supplied from the lubricating/cooling oil path 86 via the communication passage 90 into the mechanical oil pump 54 to remove air from the mechanical oil pump 54. This prevents the occurrence of air sucking abnormal sounds in the motor driven oil pump 58 in a motor travel mode and actualizes quick rise of hydraulic pressure in the mechanical oil pump 54 when starting the engine 52. <P>COPYRIGHT: (C)2009,JPO&INPIT |
