Abstract:
An air compressor comprises: a housing (60), a motor (691) coupled onto the housing (60), a transmission mechanism (69), a cylinder (61) extending from the housing (60) and having an air reservoir (63), a plurality of ducts (64,65) installed at the air reservoir (63), and a piston (62) installed in the cylinder (61) and driven by the transmission mechanism (69) and the motor (691) to input compressed air into the air reservoir (63) and output the compressed air from the ducts (64,65) of the air reservoir (63). The air compressor further comprises a pressure gauge (M) having an over-pressure protection unit which is directly coupled to one of the ducts (64,65). The pressure gauge (M) measures and indicates a change of the pressure value and, if the pressure value reaches a predetermined maximum safety pressure value, discharges air through an over-pressure protection unit.
