Injector for a fuel supply system of an internal combustion engine and fuel supply system

A fuel supply system, namely common rail fuel supply system of an internal combustion engine which is formed in particular as a large diesel internal combustion engine or ship's diesel internal combustion engine, comprising:

• a low-pressure region;
• a pump arrangement having at least one high-pressure pump to convey fuel from the low-pressure region of the fuel supply system into a high-pressure region;
• a pressure accumulator system having at least one storage unit that is permanently under high pressure is arranged in the high-pressure region between the pump arrangement and injectors associated with cylinders;
• at least one first high-pressure fuel line that is permanently under high pressure that couples the pressure accumulator system to the pump arrangement;
• at least one injector comprising:
• an injection nozzle;
• a control valve;
• at least one radially extending intermediate plate axially positioned between the injection nozzle and the control valve, wherein the at least one intermediate plate is configured as one of a valve plate and a throttle plate and clamped between the injection nozzle and the control valve;
• and
• a clamping sleeve configured to seal and cover parting surfaces between the control valve, intermediate plate, and the injection nozzle, and having radially inward directed projections,
• wherein the clamping sleeve, the injection nozzle, injection nozzle, intermediate plate, and the control valve form a clamped assembly, and
• wherein the clamped assembly formed of the injection nozzle and the control valve is configured to be mounted and unmounted as a unit;
• wherein the control valve has at a radially outer lateral surface:
• a radially inwardly directed recess configured as a circumferential groove,
• wherein the clamping sleeve has the at least one radially inwardly directed projection configured as a circumferential bead at a first portion that cooperates with the at least one of the radially inwardly directed recess of the control valve to fix the clamping sleeve in a position on the control valve,
• wherein the clamping sleeve has an internal thread at a second portion that mates with the external thread of the injection nozzle.
