Liquid reservoir, method for manufacturing same, and compressor having same

A method for manufacturing a liquid reservoir, comprising:

• preparing a barrel comprising an internal space, an open upper end and an open lower end, the internal space being between the open upper end and the open lower end;
• press-fitting a partition plate into the internal space of the barrel and welding the partition plate, that is press-fitted into the internal space of the barrel, to the barrel by in-furnace brazing;
• arranging a valve core assembly in a predetermined position within the internal space of the barrel and press-fitting a limit plate into the internal space of the barrel to limit the valve core assembly;
• narrowing the upper end of the barrel to form an air inlet and narrowing the lower end of the barrel to form an air outlet;
• and
• coupling an air inlet tube to the air inlet and coupling an air outlet tube to the air outlet,
• wherein:
• the partition plate divides the internal space of the barrel into an air inlet chamber in communication with the air inlet and an air outlet chamber in communication with the air outlet;
• and
• a filter screen is located inside the air inlet chamber between the air inlet and the partition plate.
