摘要： When an engine stall is likely to occur, the pressure of the back pressure chamber of a relief pressure valve is released to adjust the relief pressure of the relief pressure valve. This actuates a pressure compensating circuit to release the pressure in a control circuit to an oil tank. Thus, a rapid increase of the pressure due to a cargo handling operation is restricted, and an engine stall due to insufficient torque of the engine is avoided.

摘要： A hydraulic mechanism is mounted on a forklift (10). The hydraulic mechanism has a control valve (39, 41) and a pressure compensation circuit (37) for compensating pressure within the hydraulic mechanism. The pressure compensation circuit has a relief pressure valve (48) and an unloading valve (50) for releasing pressure within the pressure compensation circuit to a discharge oil passage (24). Upon instructed to perform cargo handling operation, the unloading valve is switched to an open state, and the relief pressure valve is thereby actuated, so that rapid increase of pressure within the circuit is avoided. Further, the unloading valve is switched to an open state, and the pressure within the hydraulic mechanism is thereby released to the discharge oil passage, so that the cargo handling operation by the tilt cylinder (15) and the lift (16) cylinder is restricted.

摘要翻译：当可能发生发动机失速时，释放压力阀的背压室的压力被释放以调节安全压力阀的安全压力。这就启动了压力补偿回路，以将控制回路中的压力释放到油箱中。因此，由于货物处理操作而导致的压力的快速增加受到限制，并且避免了由于发动机的扭矩不足而引起的发动机失速。
