Fuel injection valve

A fuel injection valve configured to inject fuel from an injection hole includes: a coil that is configured to generate a magnetic flux when the coil is energized; a stationary core that forms a portion of a flow passage, which is configured to conduct the fuel to the injection hole, wherein the stationary core is configured to become a passage of the magnetic flux; a movable core that is configured to be attracted toward the stationary core when the movable core becomes a passage of the magnetic flux; a passage forming portion that is placed on a downstream side of the stationary core and forms a portion of the flow passage; and a covering portion that covers a stationary boundary, which is a boundary between the passage forming portion and the stationary core, from a flow passage side of the stationary boundary where the flow passage is located.

VALVE ARRANGEMENT

A valve arrangement for applying flowable medium to a substrate, in particular hotmelt adhesive, which valve arrangement has a distribution element and a heating device, the heating device being arranged outside the distribution element and being fastened, preferably detachably, as a unit to the distribution element.

Applicator comprising a sealing membrane

The disclosure concerns an applicator (e.g. print head) for applying a coating agent (e.g. paint) to a component (e.g. motor vehicle body component), having a nozzle chamber with a plurality of nozzles for dispensing the coating agent in the form of continuous jets or droplets, the coating agent flowing during operation through the nozzle chamber to the nozzles so that the nozzle chamber is filled with the coating agent during operation. The print head further comprises a plurality of slidable valve needles associated with the individual nozzles and selectively opening or closing the respective nozzle depending on the position of the valve needles. Furthermore, the print head according to the disclosure contains an actuator chamber for receiving actuators for displacing the valve needles. In addition, the applicator according to the disclosure has a sealing element which fluidically separates the actuator chamber from the nozzle chamber in order to avoid contamination of the actuator chamber with the coating agent in the nozzle chamber. The disclosure provides that the sealing element is designed such that the individual valve needles can be displaced independently of one another without a displacement of one of the valve needles impairing the opening and closing of the nozzles at the adjacent valve needle.

VALVE FOR FLOWABLE MEDIA

A valve for flowable media having a valve housing and an elongate closure member arranged therein and which can be axially moved in a medium channel of the valve by a controllable actuator and which in a closed position abuts a valve seat and closes a discharge opening connected to the medium channel, and which is connected to a sealing element to seal the medium channel, namely, a part-piece of an elongate bellows, which moves in an axial direction during movements of the closure member and which is a hollow member made of metal, wherein another part-piece of the bellows is fixedly supported in the valve. The relative axial position between the bellows and the valve seat is adapted to a production-related deviation of the longitudinal dimension of the bellows used from a desired longitudinal dimension so that this deviation is compensated for.
