共轨式燃料喷射装置的控制装置
摘要：
本发明涉及一种共轨式燃料喷射装置的控制装置，能够避免压送泵与减压阀的同时驱动，而进行共轨压力的控制。该共轨式燃料喷射装置的控制装置包括：第一以及第二流量调整阀(12E、F)，用于对朝共轨(13)压送燃料的压送泵(12)的排出量进行调整；以及减压阀(18)，用于对共轨压力进行减压；其具备：第一驱动控制部(21)，对第二流量调整阀(12F)的电磁驱动部(32)以及减压阀(18)的电磁驱动部(33)进行控制；以及第二驱动控制部(22)，对第一流量调整阀(12E)的电磁驱动部(31)进行控制，第一驱动控制部(21)在朝减压阀(18)输出驱动指示的情况下禁止朝第二流量调整阀(12F)的驱动指示。
摘要（英）：

This invention pertains to a control device for common rail fuel injection device and allows control of common rail pressure by preventing simultaneous driving of a pressure pump and a pressure reducing valve. A control device for a common rail fuel injection device, which includes a first and a second flow regulating valve (12E, F) for regulating delivery volume of a pressure pump (12) that pressure feeds fuel to a common rail (13), and a pressure reducing valve (18) that reduces the pressure of the common rail, comprises a first drive controlling unit (21) that controls an electromagnetic driving unit (32) for the second flow regulating valve (12F) and an electromagnetic driving unit (33) for the pressure reducing valve (18), and a second drive controlling unit (22) that controls an electromagnetic driving unit (31) for the first flow regulating valve (12E). The first drive controlling unit (21) prohibits a drive instruction to the second flow regulating valve (12F) when a drive instruction is output to the pressure reducing valve (18).
