摘要： PROBLEM TO BE SOLVED: To provide a control valve capable of quickly starting a variable displacement compressor particularly in a high load. SOLUTION: In this control valve 101 of a certain mode, an operation rod 119 and a shaft 136 are rigidly connected via a housing 181 without interposing an elastic member or the like, and solenoid force is transmitted as it is to a valve element 18 of a main valve. Thus, when supplying a starting current by switching a solenoid 103 to ON from OFF, the main valve can be quickly closed. Since suction pressure Ps is high when starting the compressor in the high load particularly in summer, a valve opening state of a sub-valve can be maintained. That is, since the sub-valve can be put in the valve opening state simultaneously when closing the main valve when starting the compressor, a refrigerant can be discharged from a crankcase simultaneously when regulating the introduction of the refrigerant into the crankcase, the compressor can be quickly started.

摘要翻译：要解决的问题：提供一种能够快速启动变排量压缩机的控制阀，特别是在高负载下。解决方案：在一定模式的该控制阀101中，操作杆119和轴136经由壳体181刚性地连接，而不插入弹性部件等，螺线管力原样传递到阀主阀元件18。因此，当通过从螺线管103切换为ON而提供启动电流时，主阀可以快速关闭。由于吸入压力Ps在高负荷下启动压缩机高时，特别是在夏季，所以能够保持副阀的开阀状态。也就是说，由于当启动压缩机时关闭主阀时子阀可以同时关闭，所以当调节制冷剂进入曲轴箱时，制冷剂可同时从曲轴箱排出，压缩机可以快速启动版权所有（C）2011，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To simply achieve at low cost a structure for leading refrigerant to a back pressure chamber of a solenoid in a solenoid valve such as a control valve for a variable displacement compressor. SOLUTION: In the control valve 1, both of a plunger 33 and a shaft 36 are cylindrically formed, and assembled coaxially, to form an internal passage axially passing therethrough. A slit 38 is formed in a side surface of the shaft 36 and pressure can be introduced from the side over the total length of the same. Pressure in a pressure chamber 28 formed between a body 5 and the solenoid 3 is, therefore, easily led to the back pressure chamber 39 of the plunger 33. COPYRIGHT: (C)2011,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To achieve simplification and cost reduction in a seal structure of a control valve stored in an installation hole of an object device. SOLUTION: In the control valve 1 of a certain mode, a seal 49 is integrally molded in the end member 35 positioned on the rear end side when stored in the installation hole 152 of a compressor. When the control valve 1 is stored in its installation hole 152, the end member 35 is installed in a mode of being pressed in the installation hole 152 by the seal 49 in the latter period of its storing process. Thus, the end member 35 seals the opening part of the installation hole 152, and regulates the intrusion of an external atmosphere to the inside of the installation hole 152. The end member 35 itself has a function of sealing the inside-outside of the installation hole 152. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To improve refrigeration cycle characteristics through all load ranges by varying the charge characteristic of a thermal expansion valve which is uniquely determined by setting a set value in conformation to a thermal load placed on a heat exchanger.
SOLUTION: A bimetal 37 is arranged in a second refrigerant passage 15 through which outlet refrigerant of an evaporator 5 passes, and caused to sense the thermal load placed on the heat exchanger that is an air load of the evaporator 5. When the temperature of the refrigerant rises, the bimetal 37 works to push up a shaft 31 toward a power element 12 or to release the push-up of the shaft 31 toward the power element 12, whereby the set value is corrected in a descending or ascending direction. According to this, the charge characteristic can be set to characteristics suitable respectively to a middle and low load range and a high load range.

摘要： PROBLEM TO BE SOLVED: To make refrigerant flow in an annular passage between an inner pipe and an outer pipe to the circumferential direction keeping the same status at a part having a coaxial dual-pipe structure in a refrigerating cycle.
SOLUTION: An expansion valve body 11 is installed in a case 6 connected to a refrigerant outlet 3 of an evaporator 1, and a plurality of blades (support plates 35) for converting an axial-direction flow to a swirling flow are installed in the annular passage having the coaxial dual-pipe structure formed by housing an expansion valve 10 arranged coaxially with the case 6 for changing the axial-direction flow of the refrigerant coming out of the evaporator 1 to the swirling flow and equalizing the state of the refrigerant in the annular passage. Blades 38 are installed around an inlet port 12 of the expansion valve 10 connected with a dual pipe 32. The annular passage equally distributes the refrigerant with its status equalized by the swirl of the blades 38 to passages partitioned by a column 39 coaxially supporting a high-pressure pipe 30 and a low-pressure pipe 31.

摘要： PROBLEM TO BE SOLVED: To provide a receiver drier integrated type condenser reduced in the number of joints by O-ring seals.
SOLUTION: The receiver drier integrated type condenser is composed by integrally welding a condenser 1, a bottomed tube shaped body 8 of a receiver drier 6, and a coolant passage 7 sending a coolant from the condenser 1 to the body 8. In the receiver drier 6, a desiccant 11 is mounted in its body 8, a partition plate 12 is airtightly mounted to the neighborhood of an opening of the body 8, and outlet piping 14 piercing the partition plate 12 and sending out a liquid coolant accumulated therein is airtightly connected to the partition plate. By this, since the outlet piping 14 is connected to high pressure piping 17 to an expansion valve in the body 8 and sealed by an O-ring, the joint does not become a leaking region of a high pressure coolant.
