Abstract (en)

[origin: EP1947322A2] The injector (1) has a hydraulic coupler (39) comprising a translator piston (37), which is guided into a guide in a coupler housing. The piston is limited by a front surface of a coupler area (53), which is limited at a side of a valve piston (33) that acts at a control valve (23). The valve piston is formed in an area with a diameter and in another area with another diameter, where one of the diameters is smaller than another diameter. The valve piston is enclosed in one of the areas by a ring unit, which is movable relative to the valve piston.
