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).

摘要： Peripheral sections of two diaphragms are stacked on each other. The peripheral sections of the two diaphragms form an outer rim of a diaphragm damper. The outer rim is continuously sealed and joined by laser welding over the entire circumference of the outer rim. The thickness of the tip of the outer rim is set in correspondence with the spot diameter of a laser beam at the tip of the outer rim. A weld bead is formed by welding in the entire area of the tip of the outer rim.

摘要： A coiled wave spring used by a diaphragm damper device and arranged in a fuel chamber defined by a housing and a cover is provided. The coiled wave spring is configured to be arranged between a diaphragm damper of the diaphragm damper device and the cover. The coiled wave spring is configured to fix the diaphragm damper to the housing with its elastic force. The coiled wave spring includes a coil portion, a winding initiation portion, and a winding termination portion. The winding initiation portion and the winding termination portion form flat seat windings. The seat windings each have a larger outer diameter than the coil portion. One of the seat windings is configured to be fixed to the diaphragm damper.
