Description

technical field [0001] The invention relates to an oil-gas separation valve with a metal diaphragm structure, which belongs to the field of engine accessories. Background technique [0002] The traditional cyclone oil-gas separator uses the rubber diaphragm as the main mechanism for valve opening. The pressure of the crankcase is used to open the valve. However, due to the high pressure and high temperature in the crankcase, the rubber diaphragm will not The sheet is easily broken due to high temperature and high pressure extrusion. Once broken, the exhaust gas from the crankcase will enter the cyclone separator in a turbulent flow, which will cause the separator to fail to perform oil and gas separation normally, which will lead to Engine oil vapor mixed with crankcase hot air directly enters the engine combustion chamber, causing carbon deposits. Contents of the invention [0003] The technical problem to be solved by the present invention is: to overcome the technical ...
