    摘要: This invention relates to a chain guide rail for an internal-combustion engine, having a body portion and a pin, both made with a first material, an overmolding of a second material which covers both the pin and the body portion, and a longitudinal axis through the length of the guide rail. The pin, inserted into a housing recess in the internal-combustion engine, is restrained from moving perpendicular to the first longitudinal axis but is free to move parallel to the axis. Preferred embodiments of the present invention utilize a fastener to hold the guide rail to the housing. Preferred embodiments also utilize raised portions spaced along the guide rail which reduce the longitudinal shrinkage during cooling of the second material.

    摘要: This invention relates to a method and apparatus for recognizing the impact time of a solenoid valve armature during de-energizing. In order to obtain a detectable impact signal of the armature, a measuring current is provided in the magnet coil during the armature's downward movement to generate a magnetic measuring field. When this magnetic measuring field is changed due to the armature movement, an induction voltage is generated, which is monitored to detect the time of impact of the armature.

    摘要: An ignition system for internal combustion engines with a control unit for triggering at least one ignition final stage and means for suppressing a switch-on spark. A first embodiment of an ignition system in accordance with the present invention includes a voltage-controlled switch coupled to each output of the control unit for coupling the respective output to ground until the supply voltage ramps up to a value required for the operation of the control unit. A second embodiment of an ignition system in accordance with the present invention includes a voltage-controlled switch which is coupled to all outputs of the control unit, and which switches all outputs to ground until the supply voltage ramps up to a value required for the operation of the control unit.

    摘要: A motor-driven compressor particularly for a refrigerator has a cylinder-and-piston unit whose piston is driven from a shaft of a rotor of an electric motor, two sound-damping chambers communicating with a cylinder of the cylinder-and-piston unit, and a bearing element mounted on a stator of the electric motor and having a portion forming a main bearing for the shaft of the rotor, a relatively small bridge-like portion overlapping only a part of a winding of the electric motor, and two legs located diametrically opposite one another and mounted on the stator of the electric motor. The sound-damping chambers may be of one piece with a cover of the cylinder and the latter may be a separate member without the cover.
