Abstract
The utility model discloses a cylinder cover assembly with an oil-gas separation device integrated. An air inlet channel is formed in a cylinder cover and a filter net is arranged in a cavity of the air inlet channel. The oil-gas separation device is arranged on the cylinder cover and comprises side walls and an oil-gas chamber cover, and the side walls, the oil-gas chamber cover and the cylinder cover form an oil-gas chamber. An inner plate is arranged inside the oil-gas chamber and divides the oil-gas chamber into a depressurizing cavity and a cavity which are communicated with each other. The air inlet channel is communicated with the depressurizing cavity and a one-way valve is arranged in the depressurizing cavity. The side, close to the depressurizing cavity, of the cavity is provided with an oil return hole which is communicated with a crank shaft device, the side wall far way from the depressurizing cavity is provided with an air outlet channel, the side wall inside the cavity is provided with a set of partition plates and the partition plates incline opposite to the direction of the air outlet channel. Oil-gas mixed gas passes the filter net, enters the oil-gas chamber through the air inlet channel, and flows to an air outlet of the one-way valve through an air inlet of the one-way valve of the depressurizing cavity to be depressurized, then oil flows out through the oil return hole, and gas flows through the cavity after passing through the air outlet channel.
Description
Technical field
The utility model relates to the cylinder head of general gasoline engines, particularly a kind of cylinder cover complement of integrated oil-gas separation device.
Background technique
The gas and oil separating plant of small portable petrol engine designs on crankcase more in the market, because of the grease chamber of disembarking of the gas and oil separating plant on crankcase too near, and negative pressure is larger, and when crankshaft-link rod was worked, mist of oil was stronger on every side, be unfavorable for that deaerator separates mist of oil, certainly will cause consumption of lubricating oil large, also be unfavorable for the lifting of high speed machine rotating speed, although there is the part type that gas and oil separating plant is moved on to cylinder head, but it is simple in structure, and separating effect is not good etc.
