| 20100288238 | METHOD AND DEVICE FOR FORMING AN ELECTRIC CONTROL SIGNAL FOR AN INJECTION IMPULSE In a method or a device for forming an electric control signal for an injection impulse of a position-controlled fuel injector, particularly of a common-rail or pump-nozzle injection system, he course of the electric control signal can be selected freely in regard to th... | 11/18/2010 |
| 20090223490 | Method For Controlling A Piezoelectric Actuator And Control Unit For Controlling A Piezoelectric Actuator A method for controlling a piezoelectric actuator which displaces a control element of an injection valve includes the step of charging the actuator until a start voltage is reached. Subsequently, the actuator is discharged until a partial lifting voltage, which is main... | 09/10/2009 |
| 20080087748 | Method and Injection System for Injecting a Fluid A method for injecting a fluid, in particular a fuel, performs the following steps: A nozzle (1) which can be actuated by a piezo element (5) is provided. A current pulse (12a) is supplied to the piezo element (5). The capacity (16<... | 04/17/2008 |
| 20070240685 | Method for Controlling a Valve and Method for Controlling a Pump/Nozzle Device with a Valve A valve has a piezo actuator, a valve element, a valve body and a valve seat. At a predeterminable point in time, the valve element is controlled by a discharging process of the piezo actuator from a position in which it rests against the valve seat to a predetermined p... | 10/18/2007 |
| 20060289670 | Method and apparatus for controlling a valve, and method and apparatus for controlling a pump-nozzle apparatus with the valve A valve has a piezoelectric actuator with a valve element, a valve body and a valve seat. In order to control the valve, the valve element is moved into the valve seat from a position remote from the valve seat by means of a charging process at a prescribable first time... | 12/28/2006 |
| 20060010688 | Method for machining an edge of a high pressure-resistant component, in particular for hydro-erosively rounding an edge, and corresponding apparatus To optimize the results of rounding and therefore to optimize the high pressure resistance of the component, it is firstly proposed that prior to the machining step of hydro-erosive rounding, the edge (5) and the surfaces (4, 6) of the high pressure-resist... | 01/19/2006 |
