摘要： A pump-nozzle unit for feeding fuel into a combustion chamber of an internal combustion engine, having a controllable fuel pump, which comprises a control valve with a valve needle which is deflected by a piezo actuator, the comparatively small travel of the piezo actuator being increased by a mechanical step-up converter to the extent required for deflection of the valve needle. In order not to endanger the ability of the control valve housing to withstand pressure yet nevertheless to provide relatively wear-resistant bearing regions (80, 82) which come into contact with the mechanical step-up converter (56, 58), it is provided that the control valve housing is formed from a material with a relatively low basic hardness, for example from Ovako 677, and that the bearing regions (80, 82) of the control valve (22) are hardened further by laser means.

摘要： A method for adjusting the calibration of a circuit breaker trip mechanism including a terminal element, a bimetal element connected thereto, and a trip bar. Laser energy is applied to lanced or pre-bent surfaces of the terminal element to thermally induce displacement thereof and thereby modify a trip distance between the bimetal element and the trip bar. Where a laser beam is directed to fall on a middle leg of a lanced or pre-bent section of the terminal element, the bimetal element moves in one direction relative to the trip bar. Conversely, where a laser beam is directed to fall on lateral legs of the lanced or pre-bent section of the terminal element, the bimetal element moves in an opposite direction relative to the trip bar. Thus, laser energy may be applied from the same direction, or to the same side of the trip structure, regardless of whether the trip time is to be increased or decreased.
