Fluid pressure circuit
The fluid pressure circuit optimizes pressure accumulation by concentrating force on a fewer number of drive portions during load cancellation, using a branching return flow and optional pressure booster, achieving efficient high-pressure accumulation and precise control.

AI Technical Summary
In existing fluid pressure circuits, the efficiency of pressure accumulation into an accumulator is lowered due to the head side oil chambers of the boom cylinders joining together, increasing thrust force during boom raising and dispersing load during lowering, which affects overall efficiency.
A fluid pressure circuit design where a plurality of drive portions are connected to a single accumulator, with a return flow passage branching off to a first drive portion for concentrated force application during load cancellation, and optionally incorporating a pressure booster to enhance fluid pressure accumulation.
This design allows for high-pressure accumulation of fluid in the accumulator, reducing the total piston area and enhancing the freedom of drive portion sizes and combinations, while maintaining precise control over cylinder devices.
