(Prior Art) Blow-by gas generated in the crankcase of an engine in an automobile or the like is often introduced into a rock cover without being released into the atmosphere, and then returned to an intake manifold for re-combustion. However, blow-by gas contains atomized oil droplets and carbon, and if it is returned to the intake manifold side and burned, the oil and carbon in the blow-by gas will adhere to walls, etc., causing problems and reducing lubricating oil. Since this will increase consumption, an oil separator is installed inside the rock cover or between the rock cover and the intake manifold to separate gas and liquid, so that the oil is returned to the engine and the unburned gas is returned to the intake manifold. I have to. An oil separator disposed within the rock cover does not require a pipe line for connection, and is less likely to cause the above-mentioned problems, compared to one in which the oil separator is disposed between the rock cover and the intake manifold.

An example of a rock cover with an oil separator is shown in Japanese Utility Model Publication No. 57-58326. This product has a recess with a hole in the bottom wall on the top of the rock cover, a box-shaped main body filled with metal wool material is placed on the recess, and a perforated plate is used to partition the main body and the recess. It is equipped with an outlet pipe,
The blow-by gas flows into the main body from the hole in the recess, passes through the metal wool material, and is discharged from the outlet pipe to the intake pipe, but when passing through the metal wool material, the oil in the blow-by gas adheres to the metal wool material. death,
The oil drops form and return to the engine compartment through the hole. However, since the blow-by gas inlet is provided at the bottom of the metal wool material, the oil separated by the metal wool material due to the flow of gas cannot fall to the engine side, and is lifted up by the metal wool material again. There was a problem that oil accumulated inside the material, increasing ventilation resistance or being carried away into the intake pipe.

(Problem to be solved by the invention) However, in the above conventional system, the oil separated from the blow-by gas by the oil separator accumulates on the bottom plate 1 and is no longer carried away by the flow of the blow-by gas at the inlet. separator
Since S1 is fixed to the rock cover R1 , there is a drawback that even if the rock cover R1 is removed from the engine E, the interior of the oil separator S1 cannot be cleaned or maintained.

(Means for Solving the Problems) The present invention is a concave casing with an open top surface, an inlet on one end facing the inside of the rocker cover, and a drain opening on the bottom of the rocker cover of an internal combustion engine. The body is formed integrally with the rock cover, a perforated plate and a spongy metal body are set upright inside the housing, and a lid plate with an outflow port is removably tightened with a stopper on the open surface of the housing. This is what I did.

(Function) Blow-by gas containing mist oil droplets, carbon and resin flows in from the inlet and is separated by the porous plate and the spongy metal filter. The oil content in the blow-by gas whose flow velocity is increased through the small holes of the porous plate collides with the spongy metal filter and adheres to the skeleton of the spongy metal filter.
The oil gradually moves backwards due to the flow of gas, and in the process it gradually becomes coarser and falls to the bottom as large oil droplets.

The gas from which oil has been removed flows back to the intake manifold from the outlet. The separated oil is returned to the engine through the drain pipe. The spongy metal filter traps carbon and resin, gradually increasing ventilation resistance and inhibiting the flow of blow-by gas. Accordingly, the fasteners are removed at regular intervals to clean the perforated plate and the spongy metal filter.

FIG. 3 is a cross-sectional view of FIG. 1, in which oil separated from gas and liquid drains through vertical grooves 15 and horizontal grooves 16 formed in the spongy metal filter 13 (the same applies to the perforated plate 12) and the substrate 14 of the holder 20. The state in which the water flows down to the pipe 8 is shown. The blow-by gas that has flowed into the oil separation chamber 11 from the inlet 7 is accelerated by passing through the holes provided in the perforated plate, collides with the spongy metal filter 13 placed later, and is formed inside the spongy metal filter 13. The oil particles of various sizes present in the gas permeate through the microscopic air space, and adhere to the skeleton of the spongy metal filter 13, which gradually moves backwards due to the gas flow. The oil gradually becomes coarser and becomes large oil droplets that fall to the bottom. Further, oil is repeatedly captured by the next porous plate 12 and spongy metal filter 13. The separated oil is transferred to substrate 1
The unburned gas is returned to the engine side from the drain pipe 8 through the vertical groove 15 and horizontal groove 16 of No. 4, and the unburned gas is returned to the intake manifold side (not shown) from the outflow pipe P and is re-burned by the engine.

(Effects of the invention) As described above, the present invention has an inlet that faces the interior of the rocker cover on one end surface, an integrally formed concave casing with a drain opening in the bottom, and an outlet that faces the inside of the rocker cover. The open surface of the casing is closed with a lid plate provided with a hole, and a perforated plate and a spongy metal filter are installed upright to allow blow-by gas to immediately flow into the oil separator without passing through complicated pipes. In addition, since the oil is filtered through a spongy metal filter having a large number of microscopic voids, it is possible to improve the oil separation rate and reduce ventilation resistance. In addition, since the lid plate can be opened without removing the cover, it is easier to clean and maintain the perforated plate clogged with carbon and resin, the spongy metal filter, and the inside of the housing. can. Furthermore, in the present invention, the oil separator is integrally arranged and fixed inside the rocker cover, and there is no part that protrudes from the upper part of the rocker cover, so it has the advantage of not being damaged.
