摘要： PROBLEM TO BE SOLVED: To provide a control valve for an clutch type variable displacement compressor capable of improving response of the compressor at the time of start as compared to a conventional compressor. SOLUTION: The control valve 50 for the clutch type variable displacement compressor 10 includes a liquid discharge passage for bleeding maintaining communication between a Pc port 58 and a Ps port 57. Communication and shut off of the liquid discharge passage for bleeding is controlled by movement of a pressure sensitive member constructing a pressure sensitive mechanism 66. When the compressor 10 is started from a stop condition, the pressure sensitive member positions to communicate the liquid discharge passage for bleeding while balance pressure in the compressor 10 at a time of stop of the compressor 10 is maintained, pressure in a suction pressure area drops with accompanying start of the compressor 10, and the pressure sensitive member moves in a direction shutting off the liquid discharge passage for bleeding when pressure in the suction pressure area reaches predetermined pressure.

摘要： PROBLEM TO BE SOLVED: To provide a control valve and a variable displacement-type compressor therewith, capable of simplifying rust-proof treatment and reducing the cost by dispensing with the masking in the rust-proofing of a yoke.
SOLUTION: A storage part 49 made of a SUS material is mounted on the yoke 48 by brazing in advance. The yoke 48 is dipped in a blackening solution of a bath temperature of 140°C for 20 minutes, and dried. The blackening solution is an alkaline solution prepared by mixing an oxidant into a concentrated caustic soda solution, and a solution of a composition free from blackening reaction is used as the SUS material. The yoke 48 excluding the storage part 49 is provided with a film of Fe3O4 (iron tetroxide), which dispenses with the masking of the storage part 49. Whereby a masking tool becomes unnecessary, the rust-proofing can be simplified and the cost can be reduced.

摘要： PROBLEM TO BE SOLVED: To provide a manufacturing method for obtaining a valve device in which a valve element in contact with a valve seat reliably closes a valve hole. SOLUTION: A safety valve in a refrigerating circuit comprises a valve body 18 having a shut-off face 18a consisting of part of a spherical face, a communication hole 16 connected to communicate with a discharge chamber of a refrigerant compressor, whose opening is adjusted by the valve body 18, a valve seat 24 formed by an opening portion of the communication hole 16, and an energizing spring for energizing the valve body 18 toward the valve seat 24. When pressure in the discharge chamber rises to abnormal high pressure, the valve body 18 is moved apart from the valve seat 24 against the spring force of the energizing spring, and then the safety valve releases refrigerant gas in the discharge chamber to the atmospheric air. In manufacturing the safety valve, a machining tool 31 with a convex spherical machining surface 18a having the same radius of curvature as the shut-off face 18a of the valve body 18 is prepared and positioned with respect to the valve seat 24, and then the machining surface 18a of the machining tool 31 is pushed against the valve seat 24 to form the valve seat 24 into a shape along the machining surface 18a.

摘要： PROBLEM TO BE SOLVED: To provide a displacement control structure of a variable displacement compressor capable of making the prevention of the malfunction in a rod and the prevention of the worsening in a displacement control be compatible. SOLUTION: In a discharge pressure atmosphere Pd of a refrigerant circulating circuit, pressure of a first pressure range PdH at a high pressure side is introduced into a first chamber 55 of a control valve CV1, and pressure of a second pressure range PdL at a low pressure is into a second chamber 56 of the control valve CV1. A pressure sensing member 54 of the control valve CV1 positions the rod 40 (valve body 43) based on the pressure difference between the first chamber 55 and the second chamber 56 so as to change the discharge displacement of the variable displacement compressor into the side for canceling the variation in the pressure difference to adjust the opening of an air feed passage 30. The air feed passage 30 connects the second pressure range PdL of the discharge pressure atmosphere Pd and a crank chamber 15 of the compressor. In the control valve CV1, a valve port 47a adjacent to the second chamber 56 via a partition wall 41 is connected to the second pressure range PdL which is the same as the second chamber 56 via an upstream side part of the air feed passage 30.
