FIELD: engines and pumps.
SUBSTANCE: lubricator 17 comprises lubricant source 13 and opening 5 to feed lubricant on to friction surface 17. Lubricant is carried from source 13 to said opening 5. Switching element 1 and piston assy 3 are arranged between lubricant source 13 and lubricant feed opening 5. Piston assy 3 has first chamber 11 and second chamber 12 separated by moving piston 4. Switching element 1 communicates opening 5 with either first chamber 11 or second chamber 12. Said chamber are intercommunicated via sole multi-way valve. Invention covers also diesel engine with above described lubricator.
EFFECT: simplified design, decreased size.
