Control system of hydraulic torque converter of transport vehicle

摘要

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