Valve gear

Abstract

Abstract PURPOSE: To prevent the loss of pressure from increasing and a ball valve from vibrating in the valve gear by a method wherein a stopper guide body is provided in order to make the passage area formed between the inner circumferential surfaces of the connecting ends of the tube bodies almost equal to the passage area of the fluid in the tube body. CONSTITUTION: The passage area of the refrigerant formed between a guide stopper body 27 and the inner circumferential surface of the connecting end of a refrigerant tube 16, or the total area of a partition space part constructed by partitioning through a guide part 29 a space part formed between the outer circumferential surface of the stopper part 28 and the inner circumferential surface of the connecting end of the refrigerant tube 16 is equalized almost to the refrigerant passage area of the refrigerant tube 16. Accordingly, the loss of pressure of the refrigerant can be made small and can make the refrigerant flow smooth and the ball valve 26 does not vibrate because of the strong back pressure being applied on the ball valve 26.
