FUEL PUMP FOR A LARGE SIZE TURBO CHARGING TWO STROKE DIESEL ENGINE, CAPABLE OF BEING A MAIN PISTON LUBRICOUS WELL, AND PREVENTING A FUEL FROM ENTERING WITHIN A MAIN GAP

摘要

PURPOSE: A fuel pump for a large size turbo charging two stroke diesel engine is provided to densely and efficiently supply a lubricating/sealing oil by a first gap limited by integrating a lubricant conduit within a main plunger.;CONSTITUTION: A fuel pump for a large size turbo charging two stroke diesel engine comprises a housing(11), a main plunger(14), a pump chamber(19), more than at least one fuel ports(23,25), a second plunger(30), a second pump chamber(32), an injecting lubricant port(34), and a lubricant conduit(42). The main plunger goes and returns by a limited first gap within a main bore(15) of the housing. The pump chamber is limited by the bore and the main plunger. The fuel port is connected by a fluid with the pump chamber. The second plunger has a limited second gap, and slides down within a second bore. The second pump chamber is limited by the second bore and the second plunger. The injecting lubricant port is connected by a fluid with the second pump chamber. The lubricant conduit is arranged within the main plunger, and is connected to the second pump chamber, and is opened to the limited first gap.;COPYRIGHT KIPO 2013
