    摘要： A pump fluid driving apparatus includes a housing having a chamber, with two gears mounted within the chamber. The housing includes a first rounded wall section and a second rounded wall section, the first and second rounded wall sections defining at least a portion of the chamber. The gears have teeth located about their respective peripheries and operatively positioned with the teeth of the first gear and the teeth of the second gear intermeshed. The teeth include slotted teeth and solid teeth arranged with uniform spacing in a repeating pattern about the periphery of each of the gears, with each of the slotted teeth having a vane slot and a radially extending vane extending from the vane slot, and each radially extending vane being movable within the respective vane slot and being configured to contact the respective first or second rounded wall sections.

    摘要： A scroll compressor is provided, comprising: a compression mechanism comprising a non-orbiting scroll member and an orbiting scroll member, wherein the orbiting scroll member is axially displaceable between an engagement position and a disengagement position; a main bearing housing adapted to support the compression mechanism; a back pressure chamber formed between the orbiting scroll member and the main bearing housing, wherein the back pressure chamber is in communication with at least one of the compression chambers via a communication passage provided in the orbiting scroll member or the non-orbiting scroll member and is adapted to apply a back pressure to the orbiting scroll member to bias the orbiting scroll member toward the engagement position; and a first sealing means provided between the back pressure chamber and a suction zone of the compression mechanism and capable of maintaining sealing when the orbiting scroll member is axially displaced.

    摘要： A scroll member includes a base having a panel and a spiral blade provided to extend from the panel toward another scroll member, resin layer L1 formed on the base, and a plurality of grooves C formed on a surface of the resin layer. The plurality of grooves C are formed on the surface of resin layer L1. A cross section of each groove C has a shape similar to a U-shape or a semicircle in which the width decreases toward the deeper position and the rate of change in width increases toward the bottom. Grooves C are formed by moving an edge of a cutting tool along the original surface of the resin layer, which is originally formed on base LO by application or the like.
