PROBLEM TO BE SOLVED: To provide an electric hydraulic system capable of downsizing an electric hydraulic supply source even with constitution necessary for large hydraulic force, such as a leg lifting/lowering system.SOLUTION: An electric hydraulic system 10 is constituted as an independent hydraulic system, which is, for example, applied to a leg lifting/lowering system and includes a first hydraulic actuator 31 intermittently operating. The electric hydraulic system 10 includes: an electric hydraulic supply source (hydraulic pump 11 and an electric motor 12 configured to drive the hydraulic pump) configured to supply oil pressure to the first hydraulic actuator 31; and an accumulator 13 configured to accumulate hydraulic force from the electric hydraulic supply source, and supply the accumulated oil pressure to the first hydraulic actuator 31 in order to operate the first hydraulic actuator 31.SELECTED DRAWING: Figure 1

    【課題】 脚揚降システムのように大きな油圧力を必要とする構成であっても、電動油圧供給源をより小型化することが可能な電動油圧システムを提供する。【解決手段】 電動油圧システム10は、例えば脚揚降システムに適用され、間欠的に動作する第一油圧アクチュエータ31を含む、独立した油圧システムとして構成されている。電動油圧システム10は、第一油圧アクチュエータ31に油圧を供給する電動油圧供給源(油圧ポンプ11およびこれを駆動する電動モータ12)と、電動油圧供給源からの油圧力を蓄積するとともに、第一油圧アクチュエータ31に対して、当該第一油圧アクチュエータ31を動作させるために蓄積した油圧を供給するアキュムレータ13と、を備えている。【選択図】 図1
