AIR COMPRESSOR OF VEHICLE, PARTICULARLY REGARDING TO IMPROVING PERFORMANCE OF VEHICLE RELATED TO GENERATION OF NOISE

摘要

PURPOSE: An air compressor of a vehicle is provided to improve performance of a vehicle related to a noise by removing a suction noise generated at an air suction port by installing an expansive resonator at an air suction port of a cylinder head. CONSTITUTION: A cylinder body(51) has a compression chamber(P) inside. A piston(53) is installed in the cylinder body for generating compressed air while reciprocating in the compression chamber by driving power of an engine. A cylinder head(55) is installed at an upper part of the cylinder body and has an air suction port(57) and an air exhaust port(61) having a suction valve(59) and an exhaust vale(63) respectively so that the air suction port and the air exhaust port are communicated with the compression chamber. An expansive resonator(65) is installed at the air suction port of the cylinder head for reducing suction load of air applied to the air suction port so that the expansive resonator reduces a suction noise of air sucked through the air suction port.
