Ladder type frame for internal-combustion engine, has oil pump designed as trochoidal pump and including housing that is formed from frame walls, where axis of housing coincides with longitudinal direction of frame to form crank case base

摘要

The frame has an oil pump (7) designed as a trochoidal pump and including a housing (8) with a lid. A thrust body with a pressure regulation valve interacts with a rotor mounted in the housing. The housing is formed from the walls of the frame such that the front side of the housing is joined to the frame. The housing`s axis coincides with the longitudinal direction of the frame that forms the base of a crankcase.
