Common rail injector control module for fuel injection into diesel internal combustion engine combustion chambers has a valve body, a servo piston, sealing surfaces and a high-pressure fluid feed

摘要

A 3/2-way valve is held in a valve body (VB) (34-36). Operated by high pressure, a servo piston (SP) (32) has a slider edge (56) and a sealing surface (SS) (48) with a flat seating. The SP cooperates with the VB's SS (46) also designed as a flat seating. A high-pressure fluid feed (41) for operating the SP is controlled by a magnetic control valve (33) with a control piston (37).
