Beschreibung
Zusammenfassung:	PURPOSE: A slit type piezoelectric fuel injector is provided to instantly control the supply or cut-off of fuel and to simplify the structure of a fuel injector without forming a fluid passage. CONSTITUTION: A slit type piezoelectric fuel injector comprises a housing(10), a first valve body(20), a second valve body(30), and a driver(40). The first valve body is connected to a fuel inlet(12) for allowing fuel to flow inside. The first valve body is equipped with a plurality of first moving passages for being arranged into a ring shape. The second valve body allows the fuel to flow inside and is equipped with a plurality of second moving passages(32) arranged into a ring shape. The driver rotates the first valve body between a supply position for supplying to the second moving passage and a cut-off position for cutting off the first and second moving passages from each other.
