Is the structure of 1 gas flooding oil? The rear cylinder is used for supercharging.
2. First, push the gas rod oil into the front cylinder. This is because the force generated by the cylinder is not very large. When the front product is pushed up, open another cylinder without oil to increase the pressure. At this time, the cylinder will advance 20 mm? This 20 mm is 5 tons of pressure?
Is that right?
