This type of motor does not calculate the valve of the balance function. When the rotational speed is greater than the hydraulic oil supplied by the motor, in order to prevent the pitch caused by insufficient oil volume, it is insufficient to supplement the oil.
When the Hyundai excavator hydraulic motor drives the pump, the oil port of the hydraulic tank cannot guarantee the supply pressure required and the supplementary valve is immediately helpful. The increased pressure is replenished and the valve is used to the supply port of the hydraulic motor.
The compressed oil enters the oil port B, and the motor rotates counterclockwise.
If the plunger of the main control valve moves to the intermediate position, the oil in the motor is discharged from the left overflow valve, and the discharged oil flows into the motor in the right replenishment valve, which prevents the motor cavity.
