Summary: | The utility model relates to a four-way valve, and belongs to the technical field of air conditioners. The four-way valve comprises a main valve, the main valve comprises a valve body and a piston, the piston is arranged in the valve body, and an oil storage structure is arranged on the piston. According to the oil storage structure, a lubricating agent entering the valve body can move along with the piston, part of the lubricating agent can flow into the oil storage structure and be stored in the oil storage structure, and then the lubricating agent in the oil storage structure can flow out along with the movement process of the piston to lubricate the side wall of the piston and the inner wall of the valve body; the side wall of the piston and the inner wall of the valve body can be fully and effectively lubricated in the movement process of the piston, dry friction and galling of the valve body cannot be formed, and therefore the phenomenon that the piston is blocked and does not reverse can be avoided.
