Abstract (en)
[origin: EP2357354A2] The hydraulic system (1) has a pump unit (12) that is connected with a high-pressure accumulator (13), where the pump unit conveys pressurizing agent in the high-pressure accumulator under pressure rise. The pressure increasing units (17,18) are coupled with the high-pressure accumulator. Another high-pressure accumulator (22) is coupled with a pressure reducing unit (25). The pressurizing agent is flowed-out from the latter high-pressure accumulator, so that the pressure is reduced in the latter high-pressure accumulator. An independent claim is also included for a fuel injection system with a low pressure area.
