Lubrication system for an internal combustion engine

Abstract

TITLE: LUBRICATION SYSTEM FOR AN INTERNAL COMBUSTION ENGINE In one aspect, a lubrication system according to the present invention is characterized by a lubrication system for an internal combustion engine, comprising a pressureless lubricant collection chamber; a lubricant pump having a pump inlet fluidly coupled to the collection chamber; and a pump outlet fluidly coupled to a lubricant filter module. A control valve is provided With a bias member. The control valve is controlled by a terminal pressure derived from the lubricant gallery against a bias force provided by the bias member, so that in case of underpressure of the lubricant gallery the bias member actuates the control valve to return to its normally open condition.
