To efficiently generate a hydraulic oil pressure generation amount even in a case there is a considerable difference in a required hydraulic oil pressure generation amount between pressurization/discharge and suction of a fuel in a pressurization device in which the fuel is sucked, pressurized and discharged.SOLUTION: A pressurization device comprises: two fuel pumps; two linear actuators each for driving the fuel pump; a first hydraulic oil pressure pump that is common for the linear actuators, for supplying a hydraulic oil pressure to the linear actuators in order to discharge the fuel in the fuel pumps; and a second hydraulic oil pressure pump that is common for the linear actuators, for supplying a hydraulic oil pressure to the linear actuators in order to suck the fuel in the fuel pumps. When a first electric motor for driving the first hydraulic oil pressure pump is rotated forwards and backwards, the fuel is discharged from the fuel pumps that are different from each other, and when a second electric motor for driving the second hydraulic oil pressure pump is rotated forwards and backwards, the fuel is sucked by the fuel pumps that are different from each other.SELECTED DRAWING: Figure 2
【課題】燃料を吸入し加圧して吐出させる加圧装置において、加圧及び吐出と、燃料の吸入との間で必要とする油圧生成量の差が大きくても、この油圧生成量を効率よく生成する。【解決手段】加圧装置は、2つの燃料ポンプと、燃料ポンプそれぞれを駆動する2つのリニアアクチュエータと、前記燃料ポンプにおける前記燃料の吐出のために、前記リニアアクチュエータに油圧を供給する、前記リニアアクチュエータに共通の第1油圧ポンプと、前記燃料ポンプにおける前記燃料の吸入のために前記リニアアクチュエータに油圧を供給する、前記リニアアクチュエータに共通の第2油圧ポンプと、を備える。前記第1油圧ポンプを駆動する第1電動モータの正回転時と逆回転時では、互いに異なる前記燃料ポンプが前記燃料を吐出するように、前記第2油圧ポンプを駆動する第2電動モータの正回転時と逆回転時では、互いに異なる前記燃料ポンプが前記燃料を吸入するように構成される。【選択図】 図2
