Abstract

A valve for controlling volume flows of fuel supply systems of internal combustion engines has a conduit having an inlet and an outlet defining a flow direction. A bypass opening is provided in the conduit. A sleeve is slidably arranged in the conduit and covers in one position the bypass opening completely. The sleeve has an axial through bore that connects the inlet and the outlet. An elastic element that is arranged in the conduit and exerts onto the sleeve a force that is directed toward the inlet. A counterforce is generated by the flow resistance of the sleeve that counteracts the force of the elastic element.
