Abstract (en)
[origin: WO2018233980A1] The invention relates to a device (10) for return pressure adjustment for an injector (12), comprising a return line (14) having a first end (14a) at which a return outlet opening (12a) of the injector (12) can be directly or indirectly attached such that a return amount (16) of the injector (12) flows from the first end (14a) of the return line (14) to a second end (14b) of the return line (14), and comprising at least one valve (20) by means of which a return pressure can be adjusted at least between the first end (14a) of the return line (14) and the valve (20) in the return line (14), wherein the device (10) has an electrically adjustable throttle valve (20) as the valve (20). The invention also relates to a return block for injectors (12), a measuring device for measuring injection amounts and/or return amounts for at least one injector (12), and a test rig for at least one injector (12). The invention further relates to a method for return pressure adjustment in at least one injector (12).
