摘要: A displacement control valve (32) is connected to a variable displacement compressor. An open passage (53) in which a refrigerant gas flows is formed within a rod (31) and a valve body (30) of the displacement control valve (32). Further, an inner circumferential surface of a valve chamber (36) is formed as a guide portion (40) for moving the valve body (30) along an axis (L1) of the valve chamber (36). A valve portion (30a) of the valve body (30) is formed in a circular arc cross sectional shape along a surface of a sphere (K) in which an intermediate point (N) of a length of the guide portion (40) along the axis (L1) of the valve chamber (36) is set to a center on the axis (L1), and a distance from the intermediate point (N) to a contact point between a valve seat (36a) and the valve portion (30a) is set to a radius (r).
