Title: CONTROL DEVICE FOR COMMON RAIL FUEL INJECTION DEVICE
Abstract:
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).
