Abstract (en)
[origin: WO2017060561A1] The leakage detection arrangement for detecting a leakage in a fuel injection system comprises a fluid chamber (1) arrangeable in fluid communication with a leakage channel (2, 3), an indicator element (5) that is configured to move due to fuel pressure in the fluid chamber (1) from a retracted position to a protruding position thus indicating a leakage, and a retaining element (6), which is arranged around the indicator element (5) and configured to keep the indicator element (5) in the retracted position and allow movement of the indicator element (5) to the protruding position when the force applied to the indicator element (5) by the fuel pressure in the fluid chamber (1) exceeds a predetermined threshold. The arrangement comprises a groove (7) which is arranged in a part (8) surrounding the indicator element (5) and which is configured to accommodate the retaining element (6).
