Title:
HYDRAULIC CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2007010090
Kind Code:
A
Abstract:
To optimally supply hydraulic pressure in restarting from the state of idling stop.
This hydraulic control device has oil pumps 50, 51 each having a plurality of discharge ports. It comprises a selector valve 108 for communicating a sub pump 51 with a hydraulic pressure requiring part 270 with the movement of a built-in spool 109 when hydraulic pressure in the main pump 50 is a predetermined valve or lower. When hydraulic pressure in the main pump 50 is lower, the selector valve 108 is switched so that hydraulic pressure from the sub pump 51 is supplied to the hydraulic pressure requiring part 270. Thus, hydraulic pressure in the hydraulic pressure requiring part 270 is stabilized.
