Air compressor

摘要

An air compressor includes a machine base, a transmission device, a cylinder, a valve, an automatic pressure-releasing valve and a manual pressure-releasing valve. When a pressure gauge indicates that air pressure is excessive, surplus pressure can be released either by the automatic pressure-releasing valve or by the manual pressure-releasing valve, able to protect the components in the air compressor from damaged and ensure safety of a tire receiving compressed air from the air compressor.
