[0002] The main oil channel limit valve is a valve inside the engine used to limit the oil level and oil pressure. It is also called the main oil channel pressure limiting valve. Its function is to relieve pressure when the oil pressure is too high to maintain normal oil pressure in the main oil channel. The pressure limiting valve is generally installed on the oil pump so that it can be tested and adjusted on the test bench together with the oil pump to check and adjust the oil output and oil pressure of the oil pump. However, some engines also install the pressure limiting valve on the main oil channel of the cylinder block or on the assembly seat of the coarse filter.

[0003] At present, the main oil channel limit valve is installed on the main oil pipeline by using a flange and bolts. When the limit valve needs to be repaired or replaced, the bolts need to be disassembled one by one to disassemble the limit valve, which is inconvenient for disassembly and assembly of the main oil channel limit valve and increases the labor intensity of the staff. Therefore, a main oil channel limit valve is proposed. Utility Model Content
