- the connecting part has a variety of flow openings through which fuel from a step out through the inner opening and outside the Connecting part to the valve closing body or to one interacting with the valve closing body Valve seat surface can flow. It also points out Connecting pipe one running the entire length Longitudinal slot through which due to its large area hydraulic flow cross section fuel very quickly can flow coming from the inner passage opening. The most of the fuel to be sprayed is already flowing over the length of the connecting part out of this, while a small remaining amount is only at the Ball surface emerges from the connecting part.
- the electromagnetically actuated valve according to the invention with the characteristic features of the main claim has the Advantage that it is particularly simple is inexpensive to manufacture. Is of particular advantage doing that an extremely simple and inexpensive Connection between a striker and a spherical valve closing body can be achieved. It is the closing body carrier in an end area for reaching around the valve closing body shaped such that it has a or several channels directly on the surface of the Valve closing body forms through the fuel coming in freely from an internal longitudinal bore Can flow towards a valve seat surface. With Optimal inflow becomes low manufacturing effort to the metering range of the valve. Compared to known ones Valves dispense with cross openings and slots in the one hand Closing body carrier and on the other hand bevels on Valve closing body or flow grooves in Valve seat body.
- valve closing body by means of a non-integral joining process, e.g. B. by pressing or flanging on the closing body carrier Fasten. It is advantageous if the end area of the Closing body carrier in the downstream direction still over a spherical equator of the spherical valve closing body protrudes.
- the anchor can be used directly even serve as a closing body carrier, so that together with the valve closing body a two-part valve needle is present.
- a valve needle is particularly simple and inexpensive to manufacture and has reduced through the Number of parts only a single connection point.
- the longitudinal bore of the armature is advantageous Flow arms formed that directly into the channels in the Pass over the end area of the closing body support. Especially such flow arms and channels are effective Formable spaces.
