Abstract

In a valve, the number of components of the valve pipe is reduced, so that the number of joints and connecting points is also reduced,. The entire valve pipe is manufactured from magnetically conductive material, so that one can dispense with non-magnetic adapters. The valve is especially suited for use in fuel-injection systems of mixture-compressing internal-combustion engines having externally supplied ignition.
