Title:
HYDRAULIC PRESSURE SUPPLY DEVICE FOR VEHICLES
Document Type and Number:
WIPO Patent Application WO/2015/046560
Kind Code:
A1
Abstract:
In order to provide a hydraulic pressure supply device capable of making the overall device more compact by sharing oil path-forming members and forming compact oil paths, by using a mechanical oil pump and an electric oil pump, this hydraulic pressure supply device comprises: a first surface that a first rotor of the mechanical oil pump comes in contact with; a second surface that a second rotor of the electric oil pump comes in contact with and facing the opposite direction to the first surface; and an intake oil path and a discharge oil path for the mechanical oil pump and an intake oil path and a discharge oil path for the electric oil pump, between the first surface and the second surface. The rotation axis center of the first rotor and the rotation axis center of the second rotor are arranged parallel and the rotation direction of the first rotor is opposite to the rotation direction of the second rotor.
