Rapid Response Torque Control

General

The Hydraulics, Inc. Rapid Response Torque Control (pressure compensator) provides control of the swashplate angle within the pump of a hydrostatic closed-loop system, thereby giving precise control of the output pressure of the pump. The speed at which the pressure control system reacts, provides protection for the prime mover and the driven load. The rapid response torque control will work even in the systems that may require the pump to be driven over-center in order to maintain constant pressure in the high pressure loop. Torque control kits are available to provide pressure control for one or both ports of the hydrostatic pump, and for systems involving two transmissions driving a common load.

Application

The torque control system has been applied to Dynapower, Eaton, and Sundstrand hydrostatic drives. The schematics shown herein are as applied to Sundstrand Series 20 thru 27 and are for reference to other manufacturers systems. Hydraulics, Inc. is not responsible for the effects of applications of the rapid response control to Dynapower, Eaton, Sundstrand, or other company products and their warranties.
