ACTUATING UNIT FOR A PIEZO-ELECTRICALLY CONTROLLED FUEL INJECTION VALVE |
摘要 |
<p>An actuator unit which is suitable for actuating a fuel injection valve of an injection system for internal combustion engines includes a piezoelectric actuator and a hollow body embodied as a spring. The service life of the actuator unit can be improved by designing the hollow body to eliminate or minimize bending stresses on the piezoelectric actuator.</p> |
