PURPOSE: To make a positive separation between a high pressure circuit and a low pressure circuit within a fluid control valve when a compressor is operated and get a fluid control valve having a high reliability by a method wherein a position setting and inserting with an inner circumferential projection of a main body forming a high pressure valve part is set, a low pressure valve fixed to the main body with a roll fitting is provided, and a filter is placed between the high pressure valve part and the low pressure valve part.

CONSTITUTION: Low pressure refrigerant evaporated by an evaporator 5 passes through a low pressure refrigerant inlet pipe 51 and the second leaf valve 50 is released by a low pressure valve seat 48c of the third seat 48 by its refrigerant pressure, and the second leaf valve 50 is abutted against a guide 46. At this time, some foreign material passes through the low pressure refrigerant inlet pipe 51 together with the low pressure refrigerant and into the fluid control valve 31. The foreign material can be prevented from entering the high pressure valve 32 with a filter 52.
