Abstract

Piezoelektryczny wtryskiwacz gazowy wyposażony jest w odkształcalną płytkę sterującą (5) jego otwieraniem. Za odkształcanie płytki odpowiadają obustronnie naklejone warstwy piezoelektryczne (6 i 7), przez co znacząco skraca się czas reakcji na podany impuls zasilania. Regulacja wydatku wtryskiwacza możliwa jest do zrealizowania poprzez ograniczenie odkształcenia płytki, lub z wykorzystaniem dyszy kalibracyjnej.A piezoelectric gas injector is equipped with a deformable control plate (5) for its opening. The two-sidedly glued piezoelectric layers (6 and 7) are responsible for the deformation of the plate, which significantly shortens the response time to the supplied power pulse. Adjustment of the injector flow is possible by limiting the deformation of the plate, or by using a calibration nozzle.
