Abstract: A method is described for manufacturing a magnet coil for a valve in which first a metal base element of the valve is made available, then an electrically insulating winding support is mounted on the outer wall of the base element, and lastly a winding of the magnet coil is introduced into the winding support. Such a configuration of a magnet coil is suitable particularly in fuel injection valves which are used in mixture-compressing, spark-ignited internal combustion engines, but also in all other solenoid valves.

A metal hollow body forms an inlet-side extension of the fuel injector, a connector plug having a contact lug being attachable onto the metal hollow body in such a way that the contact lug of the connector plug can be brought into conductive connection with the contact lug (6) of the magnet coil.

Abstract: A fuel injector (1) for fuel-injection systems of internal combustion engines has a solenoid coil (10); a valve needle (3) that is mechanically linked to the solenoid coil (10) and acted upon by a restoring spring (23) in a closing direction, in order to actuate a valve-closure member (4) which, together with a valve-seat face (6), forms a sealing seat; and a sleeve (24), which prestresses the restoring spring (23). The sleeve (24) is integrally formed with a filter element (25) to form a one-part, deep-drawn filter sleeve (34), which has through-flow openings (35) for filtering the fuel flowing through the fuel injector (1).

Abstract: A process for the polymerization of olefins, in particular a process for the copolymerization of propylene with further olefins, is carried out in the presence of highly active catalyst systems comprising specifically selected metallocenes, in particular ones which bear different substituents in position 2 and position 4 on an indenyl ligand. Novel polypropylene copolymers can be obtained by this process.

Abstract: A fuel injector for fuel-injection systems of internal combustion engines in which a guide disk is provided upstream of a valve seat, the guide disk fulfilling several functions. In addition to guiding an axially movable valve needle, the guide disk takes on a flow-through function for the fuel. To this end, a passage hole having alternating guide regions and flow regions over its outer circumference is provided in the guide disk, the opening width of the passage hole defined by the guide regions being smaller than the opening width defined by the flow regions. The fuel injector is particularly suitable for use in fuel-injection systems of mixture-compressing internal combustion engines with externally supplied ignition.

Abstract: A fuel injection valve has a valve seat element having a fixed valve seat. A valve closure element coacts with the valve seat to open and close the valve. The valve seat element possesses an outer enveloping surface that is equipped with a coating made of a material other than the material of the valve seat element, or with an adhesive, by way of which a hydraulically sealed join can be achieved between the valve seat element and a valve seat support that receives the valve seat element. The fuel injection valve is suitable in particular for use in fuel injection systems of mixture-compressing spark-ignited internal combustion engines.

Abstract: A child safety seat comprises a child seat structure having a base support surface for resting on a vehicle seat cushion and a back support surface for abutting against the seat back of the vehicle seat. A rigid link is pivotally attached to the child seat structure so as to project from the child seat structure between the base support surface and the back support surface. A releasable connector is mounted on the rigid link for engagement with a standard anchorage unit associated with the vehicle seat. In the event of sudden deceleration, both the front and rear edges of the base support surface are pressed downwards into the vehicle seat cushion simultaneously. This results in a reduction of the extend of forward excursion of the child's head.

Abstract: A fuel injector for fuel-injection systems of internal combustion engines includes two preassembled, independent assemblies. A functional part includes an electromagnetic circuit and a sealing valve, while a connection part is formed mainly by a hydraulic connection and an electrical connection. In the ready-mounted injector, electrical connecting elements and hydraulic connecting elements of both assemblies cooperate, thus ensuring a reliable electrical and hydraulic connection An extrusion coat in the interconnection region provides mechanical joining of both assemblies, great stability of the valve and sufficient imperviousness.

Abstract: The electromagnetically operable valve has the an axially moveable valve needle which is formed from an armature, a valve-closure member and a connecting part connecting the two parts. The tubular connecting part has an elongated slit which, because of widenings of the starting sheet-metal part, has a smaller opening width at the end facing the valve-closure member than over its remaining axial extension. Thus, the valve-closure member can be attached very securely at the lower end of the connecting part by a welded seam, avoiding disadvantageous sink marks. The valve is suitable to be used in fuel-injection.

Abstract: A fuel injection valve includes an axially movable valve needle which has at least a closure element support and a spherical valve closure element. The closure element support receives the valve closure element in a lower recess. An end region of the closure element support fits around the valve closure element in the downstream direction beyond an equator of the valve closure element. The immovable join between valve closure element and closure element support is achieved by crimping. The fuel injection valve is particularly suitable for use in fuel injection systems of mixture-compressing spark-ignited internal combustion engines.
