Lubrication device for gear box clutch system, has slide valve that is adapted to provide quantity of oil to lubrication circuit through exchanger or without passing through exchanger depending on operation phases

摘要

The device has a slide valve (134) that is adapted to provide a quantity of oil to a lubrication circuit (132) through an exchanger (158) during an operation phase. The valve is adapted to directly provide an additional quantity of oil in the lubrication circuit without passing through the exchanger during another operation phase. The slide valve is controlled by a solenoid valve (140) based on the operation phases.
