Title:
OIL INTAKE DEVICE FOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/2014/167996
Kind Code:
A1
Abstract:
Provided is an oil intake device provided with a primary intake opening (51) which is disposed on an inflow edge (41a) of a narrow tube (41) and through which oil in an oil retention unit (20) is taken in, and a tertiary intake opening (53) which is formed in a gap between a first tapered surface (32) and a second tapered surface (42) by the displacement of the narrow tube (41) relative to a wide tube (31). The oil intake device is configured so that, if the intake pressure of an oil pump (10) is less than a prescribed pressure, only oil from the primary intake opening (51) is taken in and, if the intake pressure of the oil pump (10) is at least the prescribed pressure, the tertiary intake opening (53) is formed in the gap between the first tapered surface (32) and the second tapered surface (42) by the displacement of the narrow tube (41) relative to the wide tube (31) and air from the tertiary intake opening (53) is taken in. The drive torque of a mechanical oil pump driven by rotation transmitted from a drive source of a vehicle can be reduced and loss imparted to the drive source can be effectively reduced.
