Problems solved by technology

[0014] However, in the BSM using the conventional single-type relief valve, oil efficiency loss and output loss occur due to excessive drive torque
In particular, since the BSM uses a method in which the safety valve is simply opened or closed according to the pressure of the oil discharged therefrom, the amount of oil discharged from the BSM cannot be properly controlled, and thus the BSM cannot effectively cope with various operating areas, resulting in Loss of BSM

Abstract

A dual relief valve apparatus of a Balance Shaft and Oil Pump Module (BSM) of a vehicle engine may include the pump housing, and a primary relief valve and a secondary relief valve mounted inside the pump housing, wherein the primary relief valve and the secondary relief valve may be sequentially opened or closed, wherein the primary relief valve may be first opened to release a first oil by a first oil discharge pressure applied thereto and sequentially the secondary relief valve may be opened to release a second oil by a second oil discharge pressure applied thereto, the first oil discharge pressure being relatively smaller than the second oil discharge pressure.

Description

technical field [0001] The invention relates to a dual relief valve for a balance shaft and oil pump module (BSM) of a vehicle engine. More particularly, the present invention relates to a dual safety valve of a BSM for a vehicle engine that can maintain the pressure of oil discharged from the BSM for a vehicle engine at an appropriate pressure. Background technique [0002] In general, lubrication of a vehicle engine is extremely important in order to reduce frictional resistance inside the engine and to cool the inside of the engine. [0003] Lubrication of a vehicle engine is typically performed on everything from the valve gear to the cylinders and major moving parts. For example, the important role of lubrication is not only to reduce the frictional resistance of the crankshaft, connecting rod and piston among the main moving parts, but also to cool the piston and cylinder. The sealing performance of the piston and cylinder is maintained by the engine oil. [0004] E...
