Title:
LUBRICATING DEVICE FOR AUTOMATIC TRANSMISSION
Document Type and Number:
Japanese Patent JP2012180867
Kind Code:
A
Abstract:
To directly supply lubricating oil to a predetermined friction element with appropriate timing by one selector valve when the friction element is slip-controlled.
When the predetermined friction element (brake B-2) is engaged, engagement pressure is supplied to a control oil chamber for the selector valve 40, an input port a and an output port b are blocked (C), and supply of the lubricating oil to the brake B-2 is stopped. Even if the brake B-2 is released, the input port a and output port b are blocked (A). During slip control at a predetermined intermediate pressure, the predetermined pressure is supplied to the control oil chamber 43, thereby allowing the input port a to communicate with the output port b (B).
