PURPOSE: An airless pump with cylinder cooling function is provided to enhance durability and coating ability by lowering the increased temperature of the cylinder. CONSTITUTION: An airless pump with cylinder cooling function(1) comprises a fluid pumping part(10) and an air-jet system(20). The fluid pump part is installed at the lower side of a shelf(3) installed in a cart(2). The air-jet system is installed at the upper side of the shelf. The fluid pump part inhales the fluid through a fluid inlet tube(12), and compresses and provides the inhaled fluid to a supply tube(14) connected to a spray gun(13). The air-jet system includes an air control(21), a cover(22) for noise, and a support in which exhausting holes(24) are formed. An air chamber(25) is formed at the lower side of the exhausting holes and an air induction pipe(26) is piped in the air chamber. The other end of the air induction pipe is combined with a supply tube(17).
