More Information
Summary:The supply (1) has a cover plate (2) provided with an aperture (3) and designed such that the aperture is variable by piezo effect. The cover plate passes oil as pressurizing medium to a bearing via the aperture. The cover plate is made of material that represents the piezo effect, and electrically connected to a power supply (4) such that the cover plate experiences a potential difference. The power supply is adjusted such that maximum oil passes via the aperture. An independent claim is also included for a method for controlling a pressurizing medium supply for a bearing. Die Erfindung betrifft eine Blende (2) mit einer Blendenöffnung (3) für die Ölzufuhr für ein Radialkippsegmentlager, wobei die Blendenöffnung (3) durch einen Piezo-Effekt verstellbar ist.
