Abstract
An oil pressure regulator includes a chamber that extends between an oil supply line and an oil bypass line. The chamber extends from a closed end of the chamber to an open end of the chamber. The regulator includes a plunger that is positioned within the chamber. The plunger is movable within the chamber between a first position preventing oil flow from the oil supply line to the oil bypass line, and a second position allowing oil flow from the oil supply line to the oil bypass line. Also, the regulator includes a compression spring that is positioned within the chamber between the plunger and the closed end. When the plunger is in the first position, the compression spring is in an uncompressed state, and when the plunger is in the second position, the compression spring is in a compressed state.
