VALVE BLOCK FOR A HIGH PRESSURE MEMORY OF A COMMON RAIL HEAVY OIL INJECTION

摘要

In a valve block (13) for a high pressure accumulator of a common rail heavy oil injection system for internal combustion engines with a pressure relief valve (16), wherein the pressure-limiting valve (16) with its high-pressure port side (17) is accommodated in the valve block (13) and the valve block (13) is a leakage return line (15), and a low pressure port (27) of the pressure limiting valve (16) to the valve block (13) is connected and with the leakage return (15) connected to the valve block (13) with at least one other valve, a purge valve ( 21), provided that, with its high-pressure connection side (22) incorporated in the valve block (13).
