Definitions
- valve member interacts with a first valve seat in a first switching position and with a second valve seat in a second switching position, the valve chamber being sealed against the leakage oil chamber in the first switching position and connected to the leakage oil chamber in the second switching position.
- FIG. 1 shows a longitudinal section through a fuel injection valve according to the invention in its essential area
- a second valve seat 64 is formed in the valve chamber 68, on which the flattened side of the valve member 60 can come to rest.
- a connecting channel 74 is closed, which also opens into the valve chamber 68 and is connected to the high-pressure channel 10 via a transverse channel 76.
- Figure 4 shows a cross section through Figure 3 along the line IV-IV. The course of the transverse channel 76 as a semicircular groove on the contact surface of the intermediate disk 9 facing the intermediate body 7 becomes clear here.
- the inlet throttle 70, the outlet throttle 72, the connecting duct 74 and the high-pressure duct 10 are also clearly visible in the cross section shown there.
