<p>PROBLEM TO BE SOLVED: To achieve low vibrations, low noise, and power consumption reduction (energy saving) in an electrically-driven hydraulic pressure source of a hydraulic circuit.SOLUTION: A hydraulic circuit 40 of a hydraulic brake device 100 for a vehicle includes: one electrically-driven hydraulic pressure source 41; a reservoir R; a first supply path 414 which connects a discharge passage 413 with a reaction force liquid chamber C1; a first discharge path 415 which connects the first supply path 414 with a return flow passage 412; a second supply path 416 which connects the discharge passage 413 with a drive liquid chamber C2; and a second discharge path 417 which connects the second supply path 416 with the return passage 412. Further, the hydraulic circuit 40 includes: a first on-off valve V1; a second on-off valve V2; a third on-off valve V3; a first non-return valve V4; a second non-return valve V5; a first control valve V6; a second control valve V7; and a pair of pressure sensors S2, S3.</p> |
