摘要:
A fuel injector for fuel injection systems of internal combustion engines includes a solenoid coil; an armature acted upon in a closing direction by a restoring spring; and a valve needle, which is connected to the armature in force-locking manner and on which a valve-closure member is formed, which forms a sealing seat together with a valve seat surface. The armature strikes against a stop face of an inner pole of the solenoid coil by way of a stop face, and the armature stop face is provided with a coating. The coating has a surface structure.

摘要:
The invention relates to an adjustment device for motor vehicle seats which contains a gearing part which meshes with a gearing member to limit backlash, the gearing part is formed by a main part consisting of a main gearing and a compensation part with an elastic member arrange between the parts. A swiveling axis connects the parts. The degree of backlash of the two parts is restricted to a circular movement based on the connection through the swiveling axis.

The invention presents a vehicle seat with an adjusting mechanism, for example with a height adjustment of the seat area or with a length adjustment of a longitudinal guiding (20, 22), whereas the adjusting mechanism is provided with an electromotor (36), a step-down gear (34) and an adjusting device having a first adjusting element as well as a second adjusting element which may be adjusted relative to the first adjusting element. The adjusting mechanism is additionally provided with a constantly engaged brake (38) that is leading to a braking moment in both senses of rotation of the electromotor (36), the braking moment being calculated so as to be considerably smaller than the active driving moment of the electromotor (36) but so as to be bigger than the passive torques occurring during normal operation of the vehicle due to all kinds of acceleration and loads.
