Transport vehicle hydraulic torque converter control - includes auxiliary pump communicating with discharge line of pump to space formed by converter wheels and coupling space
The space formed by the converter wheels and the space of the coupling which locks the wheels are in communication, through a change-over valve actuated by a signal of the RPM transmitter of the engine shaft of the transport of the RPM transmitter of the engine shaft of the transport vehicle, with the discharge line of the pump. The line communicates with the source of fluid via a reducing valve. The system incorporates an auxiliary pump whose discharge line communicates with the discharge line of the pump through a check valve and, through a valve actuated by the pressure of fluid contained it the space of the locking coupling, with the source of fluid.
