Inventor: BOECKING FRIEDRICH
IPC: F02M59/46
Filed: 1999-08-20
Abstract: The invention relates to a injector (18), especially for controlling the injection of fuel into a combustion chamber of an internal combustion engine. The injector has a closing member (30) which is subjected to the hydraulic action of an actuating device (44, 52, 54). Said actuating device has a valve body (54) which is movably guided in a control channel (44) and which is actuated by a piezoelectric actuator (52). The valve body interacts with two control cross-sections (68, 70) located one behind the other, in order to control the pressure means connections between a high pressure supply channel (24) and a discharge channel (46). The first control cross-section (68) in the direction of actuation of the valve body (54) therefor forms a seat valve (51) with said valve body (54) and the second control cross-section (70) in the direction of actuation forms a sliding valve (71).
