アキュムレータ燃料噴射系用の調圧弁

Document Type and Number:

Japanese Patent JP4653446

Kind Code:

B2

Abstract:

A pressure regulating valve, for regulating the pressure in a common rail, having a pistonlike valve member guided axially displaceably in a bore, which valve member acts on a closing element which can be pressed against a valve seat, and the valve member forms an armature of an electromagnet that can be supplied with current. The armature of the electromagnet is embodied as a permanent magnet, or the electromagnet surrounding the armature is connected to a permanent magnet likewise acting on the armature, so that even in the state without current, a magnetic force acts on the valve member. In this way, even in the event of a failure of the electromagnetic regulation, a pressure is generated at the valve outlet. In the state when current is supplied, the closing force of the valve can be regulated over the entire pressure range.
