Fuel supply device for pressure accumulation fuel injection system, has throttle insert arranged upstream of control valve to limit flow rate of fuel filtered by fuel filter, where high pressure of feed pump is applied on filter

摘要

The device has a control valve (10) arranged downstream of a feed pump (9) to control fuel amount supplied from the pump (9) to a high-pressure pump (8). A fuel filter (30) is arranged between the pump (9) and the valve to filter the fuel that is let out via the pump (9). A throttle insert (34) is arranged upstream of the valve to limit flow rate of fuel filtered by the filter. A high pressure of the pump (9) is applied on the filter.
