Abstract

A fuel device which has a high-pressure fuel source from which a number of fuel injection valves, which are each controlled by a 3-way valve, are supplied with fuel. This 3-way valve has a valve member with a closing body provided with sealing faces that cooperates with valve seats and in addition, in its closed positions, defines pressure-exposed surfaces that produce resulting forces that are active in the respective closed position of the closing body.
