摘要： PROBLEM TO BE SOLVED: To provide a control valve of a variable displacement type compressor allowing inexpensive manufacturing of a constitution for an autonomous control in a direction for reducing discharge capacity by forcibly opening a valve of an air supply passage and reduction of the discharge capacity by surely opening the valve of the air supply passage. SOLUTION: In a valve chest 42 of the control valve CV1, a valve element part 48 for opening/closing the air supply passage 33 is provided by contacting/separating with/from a valve seat 49 provided in the valve chest 42. In a pressure-sensitive chamber 45, an inlet pressure sensitive member 50 related to positioning of the valve element part 48 in the valve chest 42 by displacing based on pressure fluctuation of an inlet chamber 26. The inlet pressure sensitive member 50 is connected to the valve element part 48 in operation. A valve element energizing plate 60 is disposed between the inlet pressure sensitive member 50 and an internal surface of the pressure-sensitive chamber 45. The valve element part energizing plate 60 forcibly moves the valve element part 48 in a direction away from the valve seat 49 by its own deformation when a temperature reaches a prescribed temperature.

摘要： PROBLEM TO BE SOLVED: To provide a control valve for a variable displacement type compressor which is autonomously controllable so as to decrease the displacement by forcibly valve-opening an air supplying passage when the variable displacement type compressor is controlled to make displacement large and poor lubrication is generated, and preventing the temperature rise of the variable displacement type compressor. SOLUTION: In a valve chamber 53 divided in a valve house 50 of a flow rate control valve CV1, a valve element 57 contacting and separating with/from a valve seat 58 provided in the valve chamber 53 to open and close the air supplying passage 38 is provided. Furthermore, in the flow rate control valve CV1, a valve element energizing plate 74 is arranged between a moving iron core 71 and a fixed iron core 69. When a temperature reaches a predetermined temperature, the valve element energizing plate 74 forcibly moves the valve element 57 in a direction separating from the valve seat 58 through the moving iron core 71 by its deformation.

The urging force of the valve body part urging plate 60 when the temperature reaches the predetermined temperature is set to be larger than the urging force of the valve opening spring 57 in a state where the electromagnetic actuator part 52 is not energized.

摘要： PROBLEM TO BE SOLVED: To almost constantly keep the blowout temperature of the cooling air by correcting a pressure loss between a refrigerant gas outlet of an evaporator and an inlet port of a compressor in a normal operation, and perform the quick cooling when a temperature of a room to be cooled is remarkably high. SOLUTION: In the case when a temperature of a cabin in within a range of a normal temperature, a discharge capacity of a compressor is controlled while finely changing an opening of a valve hole 124 by a valve element 4 through the bellows 2 which is expanded and contracted by the inlet pressure Ps introduced into an inlet pressure introduction space S1 . Further in the case when the temperature of the cabin is remarkably high, the shrinkage force of the bellows 2 acts as the valve opening force on the valve element 4, a pressure sensitive moving rod 5 is displaced in the direction to compress a coil spring 6 by the increase of the discharge pressure Pd , and this displacement force is added as the valve opening force to the valve element 4. Whereby the control pressure Pc can be kept in a high condition, the compressor keeps the operating condition with a large discharge capacity, and the cooling air blowout temperature from an evaporator is kept low, to perform the quick cooling.

摘要： PURPOSE:To provide a method and device for testing fatigue by which fatigue data can be obtained in a short time and, at the same time, the cracking of a test piece due to fatigue can be surely recognized without requiring any visual inspection. CONSTITUTION:When a test piece 100 is made to resonate by giving vibrations caused by a loudspeaker 23 while one end of the test piece 100 is supported in the state of a cantilever, the amplitude of the test piece 100 decreases, because the characteristic frequency of the test piece 100 is deviated from the resonance point as the fatigue at the stress concentration part progresses. Therefore, the fatigue of the test piece can be detected when the amplitude of the test piece 100 is measured with a displacement measuring means 3.
