Abstract RU 2576563 C2

FIELD: engines and pumps.

SUBSTANCE: claimed engine 1 comprises the crank gear case chamber 7 whereat pressure pulsates at reciprocation of piston 9 and carb 25 including the diaphragm fuel pump 109. Said pump 109 comprises the pump chamber configured to suck in and to eject the fuel and the chamber 110 with diaphragm whereto the pressure is fed to actuate the pump chamber. Connecting channel 104 communicates the chamber 110 and chamber 7 and is provided with hole 103 on the side of crank gear case to be opened and closed by piston 9. Note here that chamber 110 and chamber 7 are intercommunicated at negative pressure in the chamber 7.
