Regularly, two Annular Reservoirs are designed in JA-Piston’s products. And the advantages of which are obiously:
- To keep oil for cooling and lubricating a pin, when a piston is working in a combustion chamber;
- To release the inner stress inside a metal workpiece;
- The performance of keeping oil is better than drilling oil holes under the pin hole’s bottom. Because when an engine is working, the oil is forced to be moving all around an engine through the pipes, therefore, less oil would be left at the bottom of the engine, which leads to lower pressure to force the oil moving upward from the pin’s bottom.
