Abstract
In known electromagnetically actuatable valves, a connecting tube connected to the armature has a valve closing element secured to its other end. The connecting tube has fuel flowing through it, which can exit again in the vicinity of the valve closing element via radially extending openings. To make such tubes additional work steps are required. There is proposed a novel connecting tube intended to assure easy manufacture and simple assembly with minimum weight and maximum stability. The novel connecting tube is provided with a slit extending from one end to the other, which provides the connecting tube with resilient elasticity and provides a large-area hydraulic cross section. The manufacture of the connecting tube can be accomplished easily by rolling of a sheet-metal blank. The embodiment of the connecting tube is suitable for electromagnetically actuatable valves of all kinds.
