摘要： PROBLEM TO BE SOLVED: To set a minimum tilt angle of a swash plate nearly at 0° by enabling a swing swash plate to securely return even from the tilt angle of 0° in a variable displacement swash plate type compressor. SOLUTION: The swash plate 22 is operationally connected to a drive shaft 6 via a hinge mechanism 23 so as to be tiltable and synchronously turnable. The minimum tilt angle of the swash plate 22 is set nearly at the tilt angle of 0° (in the state of the swash plate orthogonal to the drive shaft). A tilt angle reducing spring 26 and a return spring 27 are arranged at the drive shaft 6 with the swash plate 22 interposed therebetween. The return of the swash plate 22 from the tilt angle at nearly 0° to the maximum tilt angle can be secured by the cooperation of the moment of a rotating motion acting in a tilt angle increasing direction accompanied by the rotation of the swash plate 22 and the moment based on the energizing force of the return spring 27.

摘要： PROBLEM TO BE SOLVED: To sufficiently show pulsation reduction effect in a low flow rate state without causing enlargement of a variable displacement compressor by simplifying a pulsation reduction device. SOLUTION: A back pressure valve 55 rises during low displacement operation. Rise of the back pressure valve 55 induces a spool valve to be pushed up by a compression spring 54 and to close an opening part 44. Consequently, an intake passage 32 is restricted and transmission of intake pulsation due to self-excited oscillation of an intake valve is prevented. Since a cavity is blocked by the back pressure valve 55 and a circulation hole 52 and the intake passage 32 are under a communication condition when intake pulsation of specific frequency is generated, a damper chamber 58 resonates with the intake pulsation transmitted to the intake passage 32 and Helmholtz resonance effect takes place. As a result, intake pulsation of the specific frequency is attenuated, high intake pulsation reduction effect due to synergy with restriction effect can be provided, and transmission of intake pulsation to an outside can be prevented.

摘要翻译：要解决的问题：通过简化脉动降低装置，不会引起可变排量压缩机的扩大，从而在低流量状态下充分显示脉动降低效果。解决方案：在低排量操作期间，背压阀55上升。背压阀55的上升引起滑阀由压缩弹簧54向上推动并关闭开口部44.因此，进气通道32被限制，并且由于进气的自激振荡而导致进气脉动的传递阀被阻止。由于在产生特定频率的进气脉动时，背压阀55和循环孔52以及进气通道32处于空气通道的情况下，阻尼室58与传递到进气通道32的进气脉动共振和亥姆霍兹共振效应发生。结果，特定频率的进气脉动被衰减，由于与限制效果的协同作用，可以提供高的进气脉动降低效果，并且可以防止进气脉动传递到外部。版权所有（C）2008，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a valve gear hardly causing failure in operations even if a seal member is swollen. SOLUTION: A valve containing hole 57 for containing a valve element 54 is blocked by a bulkhead 60 and an operating rod 65 is inserted into an insertion hole 60a of the bulkhead 60. A valve support portion 65b having a diameter larger than that of a rod body 65a is interposed between the rod body 65a of the operating rod 65 and the valve element 54. An O ring 71 is interposed between the inner circumference of the valve containing hole 57 and the outer circumference of the rod body 65a for sealing the portion between both of the circumferences. Within the valve containing hole 57, a rod surrounding gap 66 is formed between the valve support portion 65b and the bulkhead 60, and on the outside of the rod body 65a. The volume of the rod surrounding gap 66 changes in accordance with movement of the valve support portion 65b (valve element 54). The maximum volume of the rod surrounding gap 66 is set to be larger than that of the O ring 71 in the swelling state. COPYRIGHT: (C)2004,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To solve problems in a compressor for vehicle installation wherein miniaturization is particularly demanded in recent years from the viewpoint of vehicle installation space and in consequence, miniaturization is demanded from a pulley which constitutes a power transmission mechanism, which means an increase in the rotating speed of the compressor compared with engine speed, and moreover strict durability references particularly in a high rotating speed range are demanded from the compressor in recent years, which leads to the demand of strict durability particularly from a shaft sealing device carrying out sealing operation between the interior of the compressor and the atmosphere side. SOLUTION: The rotation of the power transmission mechanism is reduced by a reduction gear. The rotation of a rotating shaft coming in sliding contact with the shaft sealing device is thereby reduced to suppress the sliding heat generation of the shaft sealing device to thereby improve the reliability of the shaft sealing device. Furthermore, the pulley constituting the power transmission mechanism can also be miniaturized. COPYRIGHT: (C)2004,JPO&NCIPI
摘要翻译：解决问题：为了解决从车辆安装空间的观点出发，近年来特别要求小型化的车辆用安装用压缩机的问题，因此需要从构成动力传递机构的滑轮小型化，意味着与发动机转速相比压缩机的转速增加，而且近年来压缩机要求严格的耐久性参考，特别是在高转速范围内，这导致严格耐久性的需求，特别是从轴封装置在压缩机内部和大气侧之间进行密封操作。解决方案：动力传递机构的旋转由减速齿轮减少。由此，与轴封装置滑动接触的旋转轴的旋转减少，从而抑制轴封装置的滑动发热，从而提高轴封装置的可靠性。此外，构成动力传递机构的滑轮也可以小型化。版权所有（C）2004，JPO＆NCIPI
