device for the alimentawione pump fuel from a serbian new for an internal combustion engine

摘要

the device comprises a high pressure pump (15) and a low pressure pump (10) connected upstream of the first.in order to avoid the harmful consequences in the case of a defect in a component of the device, the connection (13, 14,54 - 57) between the low pressure pump (10) and the high pressure pump (15) is disposed an interception valve (71).this is closed in the case of a defect in the low pressure pump (10), which prevents withdrawal of the solid particles through the high pressure pump (15).in addition, in the case where a defect in an injector can be detected by observing the conditions of operation of the internal combustion engine.is disconnected, the low pressure pump (10) so as to avoid serious damage to the engine.
