[0002] A blower is a type of fan. It is a machine that relies on the input mechanical energy to increase the gas pressure and discharge the gas. The blower operates with an eccentric rotor offset in the cylinder, and the volume change between the blades in the rotor groove sucks in, compresses, and discharges the air. During operation, the pressure difference of the blower automatically delivers lubrication to the oil drip nozzle, which drips into the cylinder to reduce friction and noise, and at the same time can prevent the gas in the cylinder from flowing back. Such a blower is also called a sliding vane blower.
