Abstract

PURPOSE:To provide one vlave with both functions to close an inlet path as well as to regulate the flow amount of a coolant carrier in accordance with the load therefore by a method wherein the valve into which a plug regulate the flow amount and an opening and closing plug are fitted is arranged at the inlet path of the coolant carrier for a needle valve and a filter for the automatic expansion valve. CONSTITUTION:The needle valve 6, regulating the opening degree of a valve port 4 in accordance with a temperature, is arranged between the inlet path 2 and the outlet path 3 of the coolant carrier while the filter 12 is arranged at the beginning end side of the inlet path 2. A regulating and opening-and-closing valve a is equipped at the inlet path 2 between the needle valve 6 and the filter 12 and a communicating hole 20 is opened or closed by turning the opening and closing plug 21 while a plurality of holes 16, 17 having different diameters may be selected to regulate the areas of the passageway by turning the regulating valve 18. Accordingly, the filter may be cleaned without pull out the coolant carrier by closing the opening and closing plug 21 while the flow amount of the coolant carrier may be regulated in accordance with the load by turning the regulating valve 18.
