やるようにしてある。 Conventionally, the present applicant previously proposed a lubrication system for a forced lubrication type horizontal engine as shown in FIG. That is, in order to shorten the oil passage for communicating between the outlet of the oil pump and the oil passage on the crankcase side, oil passages formed in the gear case wall and the crankcase wall are provided in the gear shaft. It is connected by an oil road (1983-).
No. 38273), in order to ensure a constant oil pressure from the lubricating pump 8, a pressure regulating valve 10 is provided in the oil passage P2 , and when the oil pressure exceeds a certain level, the fuel injection pump 1
A lubricating oil return hole 40 is diagonally penetrated on the 8th side so that the lubricating oil escapes and returns to the oil pan below.

性能をも低下させることが少なくなかつた。 However, in this lubricating device, the valve drive cam gear 33, idle gear 32, etc. that rotate at high speed scoop up the lubricating oil stored in the oil pan to lubricate the gears, so this stirring causes the lubricating oil to Temperature rises cause deterioration and reduce lubrication performance, and the crank chamber is filled with lubricant mist.
By entering the Blazer device, oil separation performance has often been degraded.

にしたものとして、実開昭52−2049号公報に示す
ものが提案されている。 Therefore, Japanese Utility Model Application Publication No. 52-2049 was proposed to solve the above drawback by making it possible to supply lubricating oil to the gears without stirring up the lubricating oil in the oil pan with high-speed rotating gears. The following are proposed.

内パイプの先端をギヤの上方近くにまで延ばし、
圧力調整弁から噴き出される潤滑油をオイル案内

ものである。 That is, an oil guide pipe is connected to the oil return port provided in the valve box of the pressure regulating valve, and the tip of this oil guide pipe is extended nearly above the gear.
The lubricating oil spouted from the pressure regulating valve is guided through an oil guide pipe to lubricate the meshing parts of the gear teeth.
ところが、このものでは、下記の欠点がある。 However, this method has the following drawbacks.
(イ) すなわち、圧力調整弁の弁箱から噴き出され

滑ポンプ等が高圧を受けて耐久性の低下を招
く。(a) In other words, the pressure regulating valve receives back pressure due to the line resistance that the lubricating oil that is ejected from the valve box of the pressure regulating valve receives when it flows through the oil guide pipe, and this back pressure increases the pressure of the pressure regulating valve. This becomes a disturbance factor for the set pressure, and if the disturbance occurs, the set pressure of the pressure regulating valve tends to shift to the high pressure side, so the lubrication oil pressure in the oil path tends to be on the high pressure side, and the lubricating oil supply device, lubrication pump, etc. Durability decreases due to high pressure.

ブルを招くことにもなる。(b) Moreover, it is necessary to provide an extra oil guide pipe in the forced lubrication oil path, which increases the number of parts, complicates the structure, and requires additional work to assemble the oil guide pipe to the pressure regulating valve. This requires an extra amount of oil, making the assembly process time-consuming and causing problems such as the oil guide pipe falling out.

る。 The present invention solves the above-mentioned drawbacks by providing an oil return port in the pressure regulating valve of the forced lubrication device provided on the fixed wall of the engine body, and connecting this oil return port to the side of the gear facing the fixed wall. By opening the opening toward the meshing part of the gear teeth, the lubricating oil is intensively applied to the meshing part of the gear teeth, improving lubrication performance, while also preventing the pressure regulating valve from opening. This aims to stabilize the set pressure and downsize.

Hydraulic pressure does not shift to the high pressure side. Therefore, the lubricating oil supply device, lubricating oil pump, etc. are always maintained within the set pressure, resulting in excellent durability.
