Title:
HYDRAULIC OIL SUPPLY DEVICE FOR TRANSMISSION
Document Type and Number:
Japanese Patent JP2017145871
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a hydraulic oil supply device for a transmission capable of improving pump efficiency of an oil pump.SOLUTION: In a hydraulic oil supply device 66, a flow velocity V2 of a hydraulic oil F2 flowing though a boundary portion 88 is made larger than a flow velocity V1 of a hydraulic oil F1 flowing through a first inflow port 82 in an injector 68 so that a negative pressure to a second inflow port 84 is generated in the boundary portion 88. Accordingly, the hydraulic oil is sucked into the second inflow port 84 from an oil pan 22 by the negative pressure generated to the second inflow port 84, and the hydraulic oil is sucked into an oil pump 32. As a result, it is possible to reduce the work of the oil pump 32 which is required to suck the hydraulic oil from the oil pan 22.SELECTED DRAWING: Figure 1
