Fuel injection valve has metal elastic sealing element that runs radially from its peripheral region in a radial region and covers at least part of end of piston facing away from pot floor

摘要

The fuel injection valve has a hydraulic coupler with a pot-shaped cylinder with a piston (17) and an elastic sealing element of metal (25) joined to the cylinder and piston in a sealed manner and with a peripheral region (25.1) that runs from the cylinder in the axial direction. The elastic sealing element runs radially from the peripheral region in a radial region (25.2) and covers at least part of an end of the piston facing away from the pot floor (18).
