摘要： PROBLEM TO BE SOLVED: To prevent temperature rise within a crankcase through a miniaturized simple configuration. SOLUTION: Oil is excessively reserved in a crankcase 7, and the reserved oil is agitated by a rotating swash plate 16, thereby the oil itself becomes hot, and the inside of the crankcase 7 goes into an abnormally high temperature state. When a temperature in the crankcase 7 reaches a melting point or higher of a low-melting point member 38 attached in a second extraction passage 37, the low-melting point member 38 melts, and the second extraction passage 37 is opened. Since a refrigerant gas in the crankcase 7 is in a relatively high-pressure state, it actively flows out of the second extraction passage 37, and flow rate of the refrigerant gas flowing into an intake chamber 8, is increased than at a normal state of a compressor. Consequently, the oil reserved in the crankcase 7 accompanies the refrigerant gas, and flows out into the intake chamber 8 together. Therefore, oil quantity in the crankcase 7 decreases, and as a result the temperature rise is prevented, and the compressor is maintained at a suitable temperature state. COPYRIGHT: (C)2011,JPO&INPIT
摘要翻译：要解决的问题：通过小型化的简单结构来防止曲轴箱内的温度上升。解决方案：油在曲轴箱7中被过度保留，并且保留的油被旋转的斜盘16搅动，从而油本身变热，并且曲轴箱7的内部进入异常高温状态。当曲轴箱7中的温度达到安装在第二提取通道37中的低熔点构件38的熔点或更高时，低熔点构件38熔化，第二提取通道37打开。由于曲轴箱7中的制冷剂气体处于相对高压状态，所以主动地从第二抽出通路37流出，流入进气室8的制冷剂气体的流量比正常状态压缩机因此，预留在曲轴箱7中的油伴随制冷剂气体，并一起流入进气室8。因此，曲轴箱7内的油量减少，结果能够防止温度上升，压缩机保持在合适的温度状态。版权所有（C）2011，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a seal cap capable of avoiding contact between its cap portion detached at pulling the seal cap out, and a stud bolt provided at a compressor.SOLUTION: A seal cap 20 includes: an intake side cap part 21 that blocks an intake hole 13, the cap portion being made of an elastically deformable material; a discharge side cap part 22 that blocks a discharge hole 14; a bolt insertion part 23 through which a stud bolt 15 is inserted; a base body part 27 that integrally connects the intake side cap part 21, discharge side cap part 22 and bolt insertion part 23; and a first gripping part 25 and auxiliary gripping part 26 both connected to the base body part 27. A distance K1 between a first root part 25B and the bolt insertion part 23 is set shorter than a distance K2 between the first root part 25B and the discharge side cap part 22, as the first root part 25B is provided between the bolt insertion part 23 and discharge side cap part 22, with an auxiliary root part 26C being formed nearer to an intake side cap part 21 side than the first root part 25B.

摘要： PROBLEM TO BE SOLVED: To provide a displacement control mechanism in a variable displacement type compressor, preventing the deterioration in operation efficiency of the variable displacement type compressor by making the timing of operating a second control valve appropriate and eliminating a trouble caused by slippage of operation timing of the second control valve.
SOLUTION: The displacement control mechanism in the variable displacement type compressor includes a first control valve adjusting the passage section area of a charge air passage 29. The displacement control mechanism includes a second control valve CV2. The second control valve CV2 includes a back pressure chamber 80, a valve chamber 71, a valve hole 27a, a first valve part 79 disposed in the valve chamber 71, and a back surface 81 disposed in the back pressure chamber 80, and is provided with a spool 75 making the opening of the valve hole 27a small by the first valve part 79 when the pressure in the back pressure chamber 80 acting on the back surface 81 gets higher. A check valve 90 is disposed in the charge air passage 29 between the first control valve and a crank chamber 5, and prevents refrigerant from flowing toward the first control valve from a crank chamber 5 by blocking the charge air passage 29.
