Problems solved by technology
[0003] In order to solve the problem that the residual air in the traditional hydraulic cylinder floats on the upper part of the cylinder body cavity in the prior art, it cannot be completely discharged with the oil during the working process, so that the air is subjected to instantaneous high pressure and produces the Diesel effect, which easily leads to the internal pressure of the hydraulic cylinder. Leakage and external leakage seriously reduce the defects of the service life of the hydraulic cylinder. The invention provides a high-performance hydraulic cylinder with an oil distribution device

The invention discloses a high-performance hydraulic cylinder with an oil distribution device, belonging to the hydraulic cylinder technical field, which solves the defects that air remaining in a traditional hydraulic cylinder cannot be completely discharged during the working process because of floating in the upper part of the inner cavity of the cylinder, and thus Disel effect occurs due to the instantaneous high pressure of the air, it's easy to result in internal leakage and external leakage of the hydraulic cylinder, which drastically reduces the service life of the hydraulic cylinder. The invention mainly comprises a cylinder, in which a cylinder cover and a cylinder bottom are provided and inside which a piston and a piston rod are provided, the piston rod penetrating into the cylinder cover, in which an oil channel is provided and the inner end face of which is provided with a counter bore that is provided with an oil distribution disc inside. The big end face and check end of the oil distribution disc are separately provided with an oil hole and a groove, and the groove matches with the oil channel. The hydraulic cylinder is mainly used for engineering machinery.
Description
technical field [0001] The invention belongs to the technical field of hydraulic cylinders, and in particular relates to a high-performance hydraulic cylinder with an oil distribution device. Background technique [0002] Some hydraulic cylinders in the prior art are limited by their installation positions in engineering machinery, and their oil ports are located below or on the side of the hydraulic cylinder. The residual air in the hydraulic cylinder floats on the upper part of the cylinder cavity, and cannot be completely discharged with the oil during the working process. When the hydraulic cylinder is working, the air is subjected to instantaneous high pressure to produce the Diesel effect, which is likely to burn the seal and cause it to fail, resulting in internal and external leakage of the hydraulic cylinder, which seriously affects the performance of the hydraulic cylinder and reduces the service life of the hydraulic cylinder.
