<p>PURPOSE: A hydraulic circuit and a working machine with the same are provided to reduce the cavitation of a hydraulic motor during the deceleration of the hydraulic motor by having a supplementary pressure system. CONSTITUTION: A hydraulic circuit comprises a hydraulic motor(13), a pilot pressure system, and a supplementary pressure system. The pilot pressure system supplies hydraulic fluid to one or more components of a working machine at a pilot pressure. The supplementary pressure system is connected to the pilot system, the hydraulic motor, and the hydraulic fluid. If the pressure of the hydraulic motor is partially lower than a critical pressure, the supplementary pressure system supplies the hydraulic fluid from the pilot pressure system to the hydraulic motor so that the cavitation of the hydraulic motor can be reduced during the deceleration of the hydraulic motor.</p> |
