FIELD: engines.
SUBSTANCE: invention relates to propulsion engineering, particularly to devices for monitoring technical state of plunger pairs of high pressure fuel pumps of diesel engines. Device for measurement of leakage of plunger pairs consists of base 1, located in its upper part of lever 2, 3 with spring pusher 4 and adjusting nut 5. On base 1 is rigidly fixed solenoid 6, inside which pusher moves 3. Case 11 of the plunger is fixed in barrel 10 locking nut 9. To shell 10 are connected to branch pipe 8 with valve 9 for drainage of diesel fuel. In case 11 of the plunger is installed plunger 12. In lower part of barrel 10 there are o-ring 14 and pressure pickup 13. To the device are connected step-up transformer 15, 16 control unit, indication panel 17 and 18 input panel.
EFFECT: control of technical state of plunger pairs of high pressure fuel pumps of diesel engines.
