AIR EXTRACTING DEVICE OF CLUTCH OIL LINE IN AUTOMATIC TRANSMISSION

摘要

The purpose of the present invention is to provide a clutch oil path air drawing device of an automatic transmission capable of solving an existing problem that operating oil is mixed with air by drawing the air from the operating oil supplied from a valve body to a clutch for operating a clutch piston. For the purpose, the invention provides the clutch oil path air drawing device formed by installing an air drawing valve that discharges the air mixed with the operating oil of an operating oil path part by opening an air drawing path between the operating oil path part and the outside during the initial timing of applying operating oil pressure to a side of the operating oil path part in which the operating oil is supplied from the valve body to the clutch by supplying the operating oil to the operating oil path part.
