AI Technical Summary
Technical Problem
In existing fluid pressure circuits, pressure fluctuations in the branch channel can lead to excessive supply of pressurized oil to the main channel, potentially causing inefficiencies and potential damage.
Method used
A fluid pressure circuit with a flow divider valve equipped with a pressure compensation valve that adjusts the opening degree based on differential pressure between the main and branch passages, ensuring balanced fluid distribution and preventing excessive supply to the main flow path.
Benefits of technology
The solution effectively stabilizes fluid flow rates, preventing excessive supply to the main channel and minimizing heat generation, while allowing auxiliary equipment to operate efficiently using branched fluid.

Abstract
Provided is a fluid pressure circuit which can suppress excessive feeding of a fluid to a main flow path of a switching valve side. A fluid pressure circuit 130 comprises: a fluid feed source 2; an actuator device 5 operated by means of a fluid from the fluid feed source 2; and a switching valve 4 that is provided on a flow path 24-1 between the fluid feed source 2 and the actuator device 5 and that switches flow paths 24-2 and 25. The fluid pressure circuit 130 further comprises a flow dividing valve 91 that can cause at least a part of the fluid flowing from the fluid feed source 2 to the main flow path 24-1 of the switching valve 4 side to branch to a branch flow path 27. The flow dividing valve 91 is provided with a pressure compensation valve 92 that variably adjusts the opening of the branch flow path 27 in accordance with differential pressure between the main flow path 24-1 and the branch flow path 27, and that compensates for a flowrate to the branch flow path 27.
