In the dynamic damper has a screw plug holes and build gas metering edge, hydraulic repair workshop, build gas holes due to leave the air, when compressed air is compressed, the compressed air has a shock-absorbing effect, Xianyang hydraulic pressure, the equivalent of a Miniature shock absorber. When the hole in the compressed air, oil filled, hydraulic maintenance, upon expansion, the hydraulic oil out, so that adds an additional liquidity in order to change the original flow. It is also possible to reduce or eliminate noise and vibration. After the cylinder block and valve plate repair methods are employed to check the mating surfaces for leaks, that assignment disk Vaseline oil, the drain channel blocked, hydraulic repair phone, painted a good oil valve plate flat on the platform or flat glass, then placed on the cylinder valve plate, the injection of diesel fuel in the cylinder bore, an interval of oiling, oiling that is, a hole, a hole is not oiling, observed more than 4h, the plunger holes diesel no leakage and collusion description cylinder and valve plate grinding qualified.
