FIELD: engines and pumps.SUBSTANCE: invention can be used in fuel systems with injection of LOG for mechanical carriers. Pump arranged inside LOG tank comprises flange (1) with opening for pump dismantling, container (7) to house said pump, sealed and integrated with flange (1). Opening on fuel tank inner side, at the base of container (7), has union (17) to secured LOG inlet pipe. It comprises LOG pump proper, cover for tight closure of container (7) with said pump, fastener to secure said cover to flange outer wall in opening (6), fuel suction pipe (9) to transfer LOG from tank (18) and inlet fuel pipe (8) to transfer LOG from suction pipe (9) to container (7). Device (10) to activate and deactivate LOG flow feed from fuel suction pipe (9) via fuel inlet pipe (8) to container (7) with pump that can be operated from tank outer side. Pipe feeding fuel to the engine extends through the pump sealed cover. Container (7), cover and pipe section (8) are arranged behind the device (10) to activate and deactivate LOG flow feed and allow draining the residual LOG after closure of said device (10). It incorporates electronic feed valve, feed pipe to feed fuel to LOG tank (18) and return pipe to feed LOG in tank (18).EFFECT: dismantling without draining of fuel.7 cl, 5 dwg |
