    摘要： A new type of progressive cavity compressor is intended primarily for 3 to 10 ton vapor-cycle air conditioning systems. Major working section elements include a rotor, a stator, inlet ports, an outlet endplate, and outlet check valves. The helical rotor is driven in an eccentric orbital path inside the helical stator. In the preferred embodiment, the rotor and stator helices have varying (non-uniform) pitch in the working section. Rotor-stator running clearances are tight, to minimize leakage. Two outlet check valves regulate refrigerant discharge flow and pressure. Efficient compression is provided over a wide range of compression ratios, corresponding to a wide range of ambient temperatures in an air conditioning application. The invention can improve the energy efficiency of air conditioning systems, especially at off-design conditions.

    摘要翻译： 一种新型的连续式空腔压缩机主要用于3至10吨蒸汽循环空调系统。 主要工作部分元件包括转子，定子，入口端口，出口端板和出口止回阀。 螺旋转子在螺旋定子内的偏心轨道中被驱动。 在优选实施例中，转子螺旋和定子螺旋在工作区段中具有变化的（非均匀的）螺距。 转子 - 定子运转间隙很小，以减少泄漏。 两个出口止回阀调节制冷剂排放流量和压力。 在宽范围的压缩比下提供有效的压缩，对应于空调应用中的各种环境温度。 本发明可以提高空调系统的能量效率，特别是在非设计条件下。

    摘要： The invention relates to a stator (10) for a feed pump, in particular for an eccentric screw pump, said stator (10) having a stator body (18) with a receiving opening (36) for receiving a rotor (24). In addition, the stator body (18) is designed as an elastomer body (20), at least some sections of which are reinforced with a yarn insert (38).
