Through the degree of opening of adjustment air-vent valve 261, can change the operation atmospheric pressure of gas circuit, make the utility model discloses a machine balance system can be applied to more small-size machine and heavy type machine. Specifically, the operating air pressure of the air path is reduced, so that the air path can be applied to a smaller machine, and the influence of the overlarge acceleration of deceleration on the original operating state of the working machine 100 is prevented; the air pressure of the air path is improved, the air path can be applied to a heavy machine, and the problem that the machine balance system cannot effectively decelerate due to too small deceleration air flow is avoided.
