要となり、コスト高となる欠点があつた。 FIG. 1 shows a lubricating oil supply system in an internal combustion engine, in which lubricating oil sucked up from an oil pan by a lubricating oil pump 1 is sent to a strainer 2 through a passage 7. It is further sent from the pressure regulating valve 3 to each part 5 of the engine via the main gear rally 4. In this case, an oil cooler 6 may or may not be provided between the lubricating oil pump 1 and the strainer 2.
will be installed so as to communicate with the passage 7, but this requires changing the structure of the passage 7, which requires a major change in specifications between the one without the oil cooler 6 and the one with the oil cooler 6. This has the disadvantage of high cost.

できるようにしたものである。 The present invention has been developed in view of the above-mentioned drawbacks of the conventional technology, and it is possible to change the specifications between a model without an oil cooler and a model with an oil cooler by simply replacing a few parts or adjusting other parts other than the oil cooler. Even when installing pressure valves, etc., specifications can be easily changed at low cost by simply replacing a few parts.

グである。 Hereinafter, the structure of the present invention will be explained based on one embodiment shown in the drawings. In FIG. The main body of the gear case covers the lubricating oil pump 1 driving gear 15 and the camshaft idle gear 16 driven by A lubricating oil inlet passage 17 is formed which is open and connected to the lubricating oil pump via a pipe 19 or the like, and this lubricating oil inlet passage 17 is bent in an L-shape in the middle, and is connected to the outer surface of the gear case body 11. The outlet 17b is opened to the outside.
Similarly, an inlet 20 is provided on the outer surface of the gear case body 11 above the outlet 17b of the inlet passage 17.
The lubricating oil outlet passage 0a is opened, and the outlet 20b side of the lubricating oil outlet passage 20 is connected to, for example, the lubricating oil passage 21 of the cylinder block 12,
It is designed to communicate with the strainer side. 22 is
This bypass cover is attached to the outer surface of the gear case body 11 by bolts 23, 23 so as to cover the outlet 17b of the lubricating oil inlet passage 17 and the inlet 20a of the lubricating oil outlet passage 20. is the outlet 17 of the inlet passage 17
A U-shaped bypass passage 24 is formed with an inlet 24 a that fits into the inlet 24 a of the outlet passage 20 and an outlet 24 b that fits into the inlet 20 a of the outlet passage 20 , thereby forming a U-shaped bypass passage 24 with an inlet 24 a that fits into the inlet 24 a of the outlet passage 20 .
and the exit passage 20 are communicated with each other. In FIG. 2, 25 is a gear case bottom wall plate that is joined to the cylinder block 12 side, and 26 is a gear case bottom wall plate that connects the gear case main body 11 and the bottom wall plate 25 to the cylinder block 1 side.
It shows the bolts that are fixed to 2. 27 is an O-ring.

とも可能であり、更には、バイパス蓋２２内に調
圧弁等を組込むことも可能である。 Therefore, in the above configuration, the oil that has entered the lubricating oil inlet passage 17 is transferred to the bypass passage 24.
However, if an oil cooler is required, the bypass cover 22 is removed and the bypass cover 22 is
Instead, the mounting portion of the oil cooler may be mounted so that its inlet and outlet communicate with the outlet 17b of the lubricating oil inlet passage 17 and the inlet 20a of the outlet passage 20. In this case, other lubricating device parts such as a pressure regulating valve may be installed in place of the oil cooler, or it is also possible to install both the pressure regulating valve and the oil cooler. It is also possible to incorporate etc.

トが大幅に底減されるという効果が得られる。 Therefore, according to the above-mentioned configuration of the present invention, specifications can be extremely easily changed from one with an oil cooler or pressure regulating valve to one without such parts by simply replacing the bypass cover, and the gear case body can be easily changed. Alternatively, since there is no need to make any changes to the structure of the cylinder block, it is possible to obtain the effect that costs due to changes in specifications are significantly reduced.
