Beschreibung
Zusammenfassung:	The invention provides a pressure regulating system for a working machine, comprising an oil tank in response to operation of a control valve, an actuating mechanism which does actuating actions, a first pressure regulating valve and a second pressure regulating valve, wherein fluid flows through the first pressure regulating valve and is output to the actuating mechanism from the oil tank, the second regulating valve and the first pressure regulating valve are connected by the fluid, and pressure buffer is carried out on the fluid which flows to the second pressure regulating valve, thus enabling the pressure of the fluid which is output to the actuating mechanism to be increased stably. The invention also provides a pressure regulating method for the working machine, comprising the following steps: a part of the fluid which flows through the first pressure regulating valve from the oil tank is output to the actuating mechanism of the working machine; a part of the fluid which flows through the first pressur
