Hydraulic module for fuel injector, has valve plate with bore, control valve arranged in or on valve plate, valve stem with valve-side end and actuator side end

摘要

The hydraulic module has a valve plate (4) with a bore (6), a control valve (8) arranged in or on the valve plate, a valve stem (10) with a valve-side end (12) and an actuator side end (14). The valve stem is arranged in the bore and is coupled with the control valve with the valve-side end. A coupler sleeve (16) is movably guided on the actuator-side end of the valve end. An adjuster piece (20) rests on the coupler sleeve, such that a coupler gap is formed between the adjuster piece and the valve stem. A valve piston spring (26) supports the valve stem opposite the valve plate. An independent claim is also included for a method for assembling a hydraulic module.
