Problems solved by technology

[0002] The internal combustion engine belongs to a kind of power machinery that burns fossil fuels. According to the existing technology, the internal combustion engine can be divided into gasoline engine and diesel engine. The common feature of gasoline engine and diesel engine is that fuel oil needs to be injected into the cylinder for combustion, and the gas expands to generate thrust to push the movement of the piston. Then convert this linear reciprocating motion into rotary motion output. During the combustion of fuel in the cylinder, it is necessary to control the amount of fuel injected into the cylinder, the amount of air injected and the amount of exhaust gas discharged. The control of the above amount (excluding fuel) The effective control of the cylinder valve needs to be realized, and the rocker arm of the internal combustion engine is the main way to control the valve, and the rocker arm of the internal combustion engine is mainly divided into an intake rocker arm and an exhaust rocker arm, and the push rod pushes the rocker arm to control the valve. The rod is in constant motion, the wear of the push rod is very large, and it needs to be replaced regularly for a long time

A cover plate 2 is inserted inside, and after the cover plate 2 passes through the right side of the cavity 3, it is connected by a buckle, and the buckle is embedded in the groove on the side wall of the push rod body 1; it also includes:

[0037] The partition 4, the partition 4 is embedded in the cavity 3, and the left side wall of the partition 4 is fixedly connected with the left inner wall of the cavity 3, and the front and rear sides of the partition 4 are respectively connected with the front and rear of the cavity 3. The two inner walls are riveted and fixed, and the right side wall of the partition plate 4 is in contact with a side wall of the cover plate 2 inside the cavity 3;

[0038] No....

Embodiment 2

[0044] see figure 1 , Figure 3-5 As shown, on the basis of Embodiment 1, the pushing mechanism 7 includes:

[0045] The piston 7-1, the piston 7-1 is arranged on the lower side of the partition plate 4, and the outer peripheral wall of the piston 7-1 is in contact with the inner peripheral wall of the cavity 3 and the lower surface of the partition plate 4;

[0046] Push rod 7-2, one end of the push rod 7-2 is riveted and fixed on the right side wall of the piston 7-1, and after the right end of the push rod 7-2 passes through the cover plate 2, it is exposed on the outside;

[0047] Push plate 7-3, the push plate 7-3 is suspended on the right side of the cover plate 2, and the push plate 7-3 and the right end of the push rod 7-2 are riveted and fixed, the diameter and the center of the push plate 7-3 Both are set the same as the diameter and center of the push rod body 1;

[0048] Connecting springs 7-4. There are several connecting springs 7-4, and they are riveted and ...

Embodiment 3

[0051] see image 3 , Figure 5 As shown, on the basis of Embodiment 2, the connecting springs 7-4 are provided with guide rods 11 inside, and the right end of the guide rods 11 is riveted and fixed on the left side wall of the push plate 7-3. The left end of the guide rod is inserted into the interior of the cover plate 2, and several embedding grooves 12 are opened at equal angles on the outer side of the left side wall of the cover plate 2. The left end of the guide rod 11 and the inner side wall of the embedding groove 12 are on the same plane. A limit rod 13 is riveted and fixed on the left end of the limit rod 11 , the diameter of the limit rod 13 is larger than that of the guide rod 11 , and the outer edge of the right side wall of the limit rod 13 abuts on the inner wall of the embedded groove 12 , and the limit rod 13 After the left end of the push rod passes through the insertion groove 12, it is movably inserted into the strip groove 14 on the right side wall of th...
