  • Patent number: 4015482
    Abstract: A control system for an engine driven power train having a variable torque absorption transmission mechanism typically including a torque converter, in conjunction with a hydraulic control circuit for the implement of an excavating-loading vehicle such as a loader. The control circuit comprises lift and tilt cylinder means connected via respective control valves to a pump driven by the vehicle engine. The pump also communicates with the transmission mechanism via a variable pressure regulator valve which functions to condition the transmission mechanism for a relatively high torque absorption characteristic during vehicle propelling operation so that engine torque may be efficiently transmitted to the drive wheels of the vehicle.
