摘要： A refrigeration system is disclosed in which negative energy storage is provided to significantly reduce electrical energy consumption during peak air conditioning hours. A transfer pump is provided in the system for pumping condensed and mixed phase refrigerant from the negative energy storage to an evaporator coil where it absorbs heat energy from an air conditioned space. The transfer pump is a positive displacement pump employing a rotor and vanes rotating in a pumping chamber. Dual inlets and discharges from the pumping chamber are located to balance forces on the rotor. The inlets enter the pumping chamber radially. A hermetic enclosure seals the pump and an electric drive motor to eliminate dynamic seals within the pump and thereby greatly reduce leakage of refrigeration from the system. A refrigeration overfeed system using a hermetically sealed pump according to the invention is also disclosed.

摘要： A hinged vane rotary pump including a cylindrical chamber, a rotor eccentrically mounted within the chamber, and a plurality of vanes. Each vane is hinged for pivoting movement at its approximate middle to balance hydraulic pressure across the face of the vane. The balanced pressure reduces the force applied by the vane against the chamber liner and therefore reduces wear. As one end of each vane wears against the chamber liner during operation, the axis effectively moves to the center of the vane. Preferably, stops are provided to limit movement of the vanes after maximum wear has occurred.
摘要翻译：一种铰链叶片旋转泵，包括圆柱形室，偏心地安装在室内的转子和多个叶片。每个叶片铰接以在其近似的中间枢转运动，以平衡叶片表面上的液压。平衡压力降低了叶片施加在腔室衬垫上的力，从而减少了磨损。由于每个叶片的一端在操作过程中会磨损室衬套，所以轴线有效地移动到叶片的中心。优选地，提供止动件以限制发生最大磨损之后的叶片运动。
