Abstract: A limiter device is provided in a variable displacement compressor capable of varying a discharge displacement per revolution and compressing a fluid in a cycle. The limiter device includes an operating characteristic acquiring means for acquiring a predetermined characteristic during a compression operation of the compressor, and a varying means for varying the discharge displacement of the compressor to a minimum side when the predetermined characteristic obtained by the operating characteristic acquiring means exceeds a predetermined value. Thus, the limiter device can prevent the compressor from being brought into trouble such as locking and can protect a driving belt and other auxiliary equipment on a side of an engine, while it is unnecessary to provide a pulley with a limiter function.

Abstract: A method for monitoring the mechanical condition of a reciprocating compressor having a packed-plunger cylinder is provided. An end assembly is attached to one end of the cylinder, and the strain of at least one component of the end assembly is measured as the plunger reciprocates within the cylinder. The measured strain is correlated with a crank angle to facilitate generation of a strain profile. Two pressure values related to the pressure in the cylinder are determined when the plunger is at two different locations. This facilitates generation of a cylinder pressure profile based on the correlated measured strain. The cylinder pressure profile is thus generated without the use of intrusive gauges or sensors, which may create a leak path, or create a stress concentration in the wall of the cylinder.
Abstract translation: 提供了一种用于监测具有填充柱塞缸的往复式压缩机的机械状态的方法。 端部组件附接到气缸的一端，并且当柱塞在气缸内往复运动时测量端部组件的至少一个部件的应变。 测量的应变与曲轴角度相关，以便于产生应变曲线。 当柱塞在两个不同的位置时，确定与气缸中的压力相关的两个压力值。 这有助于基于相关测量应变产生气缸压力分布。 因此，不使用可能产生泄漏路径的侵入式量规或传感器产生气缸压力分布，或在气缸的壁中产生应力集中。
