A pressurizing device for generating and metering high pressure and having a variable capacity chamber is connected to the low-pressure side pressure circuit, and the flow of hydraulic fluid to the pressure source is blocked in the low-pressure side pressure circuit when the pressurizing device is activated. A non-return means is provided to pressurize the working fluid in the low-pressure side pressure circuit by compressing the variable capacity chamber by a predetermined amount during predetermined processing, thereby making it possible to apply even higher pressure to the pressure working chamber. A multi-stage pressure type hydraulic processing machine characterized by:
