Abstract
PURPOSE: To provide the subject controlling device wherein output pressures of two forward-and-rearward movement and speed control valves are equalized at the time of straight movement, and at the time of stearing, the pressures of both valves are made unrelated, thereby to make constant the control of the oil pressure driving circuit not operating the stearing valve.
CONSTITUTION: A control circuit A of oil pressure driving circuits B and B' provided with variable pumps 2a and 2b and variable motors 8a and 8b driven thereby is provided with a forward-and-rearward movement and speed control valve 18a for controlling the control pressure of one hydraulic driving circuit B, a forward- and-rearward and speed control valve 18b for controlling the control pressure of other circuit B, and a control pressure equalizer 20 which equalizes the output pressures of said two forward-and-rearward movement and speed control valves 18a and 18b at the time of straight movement and make the same unrelated at the time of stearing. According to the above described organization, the output pressures of the valves 18a and 18b can be equalized at the time of straight movement and can be made unrelated at the time of stearing, and therefore the control pressure of the circuit can be made constant.
