Abstract
A housed valve is proposed which serves in particular as a metering and distribution valve for a fuel injection system of a mixture-compressing internal combustion engine with externally supplied ignition. The valve includes a control slide with a control edge and at least two control slits. The control edge opens the control slits to a greater or lesser extent depending on the relative movement between the control slide and the control slits. A helical spring is supported on one control slide end, the end of the spring oriented toward the control slide being bent at an angle and arranged to protrude into an opening of the control slide end, while the other end of the spring is connected in a twist-free manner with the valve housing. As a result, there is a friction-free means of securing the control slide from twisting, so that deviations in the fluid quantities metered at the individual control slits can be equalized during the assembly of the valve by retroactive machining of the control edge in the various areas associated with the control slits.
