漏洩することがない。 The same oil as the lubricating oil of the engine is injected into the high-pressure oil chamber 31 and the replenishment oil chamber 32 in the plunger case 21 in advance. Also, a part of the pressurized oil from the hydraulic pump P for lubricating the engine connected to the crankshaft 1 is constantly forced into the replenishment oil chamber 32 through the discharge port 41, the oil supply passage 40, the oil supply hole 38, and the oil hole 39. The replenishment oil chamber 32 is filled with oil. Further, the oil in the replenishment oil chamber 32 passes through the leak passage 56 and the air vent passage 51 together with the trapped air sealed in the chamber 32, and from there the oil drain hole 49,
The oil sump 48 at the bottom of the engine body E passes through the oil drain passage 50.
It is refluxed into the interior. In this case, the air trapped in the oil in the supply passage 32 passes through the leak hole 56 in the upper part and is easily discharged from the air vent passage 51 to the oil drain hole 49. The oil flowing between the hydraulic pump P, the auto adjuster A, and the oil reservoir 48 does not leak outside the engine body E.

The inner tension spring 34 pushes the plunger 2 with its elastic force.
3 upward, and swing the swing lever 9 counterclockwise in FIG. 1 via the slipper member 27 and the adjustment screw 30. As a result, the tension pulley 8 presses the loose side 51 of the transmission belt 5 inward and applies a constant tension to the transmission belt 5.
The elastic force of the auxiliary spring 14 also urges the swinging lever 9 to swing counterclockwise in FIG. 1, thereby assisting in applying tension to the transmission belt 5.

It works to push down 3. As a result, the oil pressure in the high pressure oil chamber 31 increases and the spherical valve body 3 of the check valve V
5 closes the valve port 33, it is possible to prevent oil from flowing back into the replenishment oil chamber 32, and eventually the high pressure oil chamber 31
The hydraulic pressure inside suppresses the retreat of the tension pulley 8 by counteracting the tensile force on the loose side 51 of the transmission belt 5.

適確に行われる。 During the above operation, pressurized oil from the hydraulic pump P is constantly supplied into the replenishment oil chamber 32 as described above, so even if there is some leakage of oil in the replenishment oil chamber 32, this can be compensated for immediately. By constantly replenishing oil into the replenishing oil chamber 32,
It is also easier to discharge trapped air into the chamber 32,
Overall, the tension of the transmission belt can be automatically adjusted more accurately.

る。 During operation of the engine, that is, when the hydraulic pump P is in operation, the auto adjuster A receives pressure oil from the hydraulic pump P and operates as described above. The pressing force of the auxiliary spring 14 and the elastic force of the auxiliary spring 14 act together to apply a predetermined tension to the transmission band 5. However, when the engine operation is stopped, the operation of the hydraulic pump P is also stopped, so the auto-adjustment is stopped. The supply of pressure oil to the adjuster A is also stopped, and when the engine is restarted, the oil supply to the auto adjuster A may be delayed, causing a temporary delay in the operation of the adjuster A. Here, if the auxiliary spring 14
Assuming that no elastic force is acting on the transmission band 5, the transmission band 5 becomes loose and a jump phenomenon occurs between the meshing teeth of the transmission band 5 and the driving wheels 3 and driven wheels 4 and 6. However, in the present invention, the auxiliary spring 14 always applies a constant tension to the transmission band 5 even when the engine is stopped, so the above-mentioned concern can be avoided. It will be resolved.

ンシヨナ装置全体のコンパクト化が可能になる。 In addition, the auxiliary spring 14 reduces the load on the auto-adjuster A by sharing part of the tensioning of the transmission band 5, and as a result, brings the auto-adjuster A closer to the swinging shaft 12 of the swinging lever 9. Even if the auto adjuster A has the same capacity, it can withstand the load from the transmission band 5.
This not only allows for a large adjustment allowance for the transmission band 9, but also allows the use of a short swinging lever 9, making it possible to make the entire tensioner device more compact.

る。C. Effects of the Invention As is clear from the above embodiments, according to the present invention, an endless transmission band is suspended between the driving wheel and the driven wheel supported by the engine body, and the transmission band has a loose side. In a tensioner device in a wrap transmission for an internal combustion engine, tension is applied by an oil-supplied auto-adjuster via a tensioner installed in the engine body. The swinging lever has the oil-filled auto-adjuster at its free end, and the oil-filled auto-adjuster at its intermediate portion, which cooperates with the oil-filled auto-adjuster to direct the tensioner toward the transmission band. The biasing auxiliary springs are connected to each other, and the auto adjuster and the auxiliary springs are placed on both sides of the swing lever, so that when the engine is running, the lubricating auto adjuster and the auxiliary springs prevent the swing from moving. It is possible to accurately apply a predetermined tension to the transmission band via the lever and tensioner, increasing the transmission efficiency of the wrap transmission device, and also prevents the delay in operation of the oil-filled auto-adjuster at the beginning of engine startup. Even when the transmission band is in a fixed position, a constant tension is applied to the transmission band by the auxiliary spring, so that the transmission band does not become temporarily loosened. Furthermore, since the auxiliary spring shares part of the tension that should be applied to the transmission band via the tensioner, the auto-adjuster is connected to the free end of the swing lever, and the load on the auto-adjuster is reduced. Since the auto adjuster can be moved closer to the swing fulcrum of the swing lever, not only can the adjustment allowance for the adjuster be increased, but also the effective length of the swing lever can be shortened and the tensioner can be moved closer to the swing fulcrum of the swing lever. This can contribute to making the device more compact.
