Abstract

A hydraulic circuit for a hydraulically driven vehicle comprising a pair of variable displacement hydraulic pumps, a pair of hydraulic motors each connected with the respective variable displacement pumps in a closed loop, and a straight run compensator valve connected between the respective closed loops for equalizing fluid pressure in both closed loops when the vehicle is set in a straight run thereby assuring a steady straight run of the vehicle irrespective of the difference in displacement of the respective variable displacement pumps.
