Description

The piston is a hollow cylinder that slides within the cylinder, and the outer diameter of the piston is approximately equal to the inner diameter of the cylinder. The function is to change the volume surrounded by the cylinder, or to transmit the pressure exerted by the fluid in the cylinder. The piston is in contact with the burning high-pressure gas, bears the impact pressure of the mixture gas explosion, and reciprocates in the cylinder at a very high speed, and rubs against the cylinder wall in rapid relative motion.
