Direct-coupling control device for torque converter for automatic vehicular transmission
A direct-coupling control device is described for a torque converter in an automatic vehicular transmission having a fluid torque converter provided with an input member and an output member and a direct-coupling mechanism capable of mechanically coupling the input and output members of the torque converter together, the direct-coupling control device comprising: a valve means disposed in a line connecting between the direct-coupling mechanism and a pressure supply source to control a supply of fluid pressure to the direct-coupling mechanism; a first fluid pressure output means for outputting a first fluid pressure proportionate to a vehicle speed; and a second fluid pressure output means for outputting a second fluid pressure proportionate to an engine output. The valve means includes a spool valve body having opposite ends and being moveable in a casing between an open position at which fluid pressure from the pressure source is allowed to pass to the direct-coupling mechanism for coupling.
