(3) Problems to be Solved by the Invention Incidentally, when the auto-adjuster is constructed as a hydraulic type, there are two known types: an oil-filled type and an oil-supply type, but the oil-filled type has no oil supply path. Although it has the advantage of not being necessary, there are problems with its reliability due to oil deterioration and leakage, whereas the oil replenishment type solves this problem, but requires an oil supply path and has a complicated structure. Another problem arises in that it increases costs.

In addition, in the above-mentioned oil-supplied auto-adjuster, in order to maintain an appropriate biasing force against the tensioner, it is necessary to always supply high-pressure oil above a certain pressure to the hydraulic chamber. To prevent the adjuster function from deteriorating due to a delay in the rise of hydraulic pressure,
It is desirable to connect the hydraulic pump as an oil supply source to the adjuster with the shortest possible oil path.

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 together with the trapped air sealed in the chamber 32 to the annular oil chamber 51, 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. Therefore, the oil supply system between the hydraulic pump P and the auto adjuster A constitutes a closed oil circuit, and lubricating oil is constantly supplied to the replenishment oil chamber 32 of the auto adjuster A during engine operation. No lubricating oil leaks to the outside.

In the auto adjuster A, the high pressure oil chamber 31
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 adjusting 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 tension spring 14 also urges the swinging lever 9 to swing counterclockwise in FIG. 1, thereby assisting in applying tension to the transmission belt 5.

The plunger 2 follows the elongation of the transmission belt 5, etc.
3 rises, the pressure in the high pressure oil chamber 31 decreases, so
Due to the pressure difference with the replenishment oil chamber 32, the spherical valve body 35 of the check valve V opens the valve port 33, and the oil in the replenishment oil chamber 32 is supplied to the high pressure oil chamber 31 through the valve port 33.

During the operation of the timing winding transmission T, the crankshaft 1,
When a tensile force is applied to the loose side 51 of the transmission belt 5 due to torque fluctuations acting on the valve camshaft 2, etc., this tensile force acts to push back the tension pulley 8, and further pushes the plunger through the swing lever 9. 2
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.

In this case, the pressure oil in the high-pressure oil chamber 31 is not actually the same due to the sliding gap between the plunger case 21 and the plunger 23 and the fact that the oil in the high-pressure oil chamber 31 contains some air bubbles inside. In this case, the plunger 23 sinks slightly, thereby alleviating the tensile impact acting on the loose side 51 of the transmission belt 5.

When the tensile force is released from the loose side 51 of the transmission belt 5, the plunger 23 rises again due to the elastic force of the tension spring 34, and the tension pulley 8 moves via the swing lever 9 to the slack side of the transmission belt 5. 5 Press 1 to apply a certain tension to the transmission belt 5 again,
If the transmission belt 5 has elongation, this can be compensated for. The oil in the replenishment oil chamber 32 is replenished as described above into the high pressure oil chamber 31, which is depressurized by the rise of the plunger 23.

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.

C. Effects of the Invention As is clear from the above embodiments, according to the present invention, the tensioner is pressed against the loose side of the transmission band and automatically operates in response to tension fluctuations on the loose side of the transmission band. In a tensioner device for an internal combustion engine, which is equipped with an oil-filled auto-adjuster that applies a constant tension to A unit case is formed integrally with the case or is directly connected to the unit case to be attached to the engine body, and within the unit case is an oil supply passage that directly communicates the discharge port of the hydraulic pump and the oil supply hole of the auto adjuster. , there is no need for special piping between the oil-supplied auto-adjuster and the hydraulic pump, and the seal structure between them is also unnecessary or can be extremely simplified. The structure is extremely simple and can greatly contribute to reducing costs and improving ease of assembly.
Furthermore, since the auto adjuster and the hydraulic pump, which is its oil supply source, can be placed close to each other and the oil path between them can be made extremely short, pressure oil from the hydraulic pump can be quickly delivered to the adjuster even when the engine is started. It is possible to reduce the delay in the rise of the oil pressure in the adjuster, and the adjuster can be made to function effectively immediately after the engine is started.
