Abstract: A coating solution that contains 10 to 20% by weight of epoxy resin serving as a thermosetting resin, 20 to 30% by weight of MoS2, and 5 to 10% by weight of graphite, with a remainder thereof constituted by an organic solvent, is sprayed onto a wrap portion side face of an orbiting scroll from a spray nozzle . While spraying the coating solution, the orbiting scroll is rotated on a rotating table and the spray nozzle is moved along a rectilinear movement path toward a radial direction outer side of the orbiting scroll while maintaining an attitude thereof from the start of the spraying process. After applying the coating solution, the coating solution is dried by baking, whereupon a break-in operation is performed. As a result, an elastic coating is formed at a coating thickness that enables elastic deformation in accordance with a clearance between the wrap portion side faces.

Abstract: A pump drive apparatus comprises a housing (1) that accommodates a shaft (2) and a pump impeller (3). Both rotate around the same axis (4). The impeller rotates against the housing on at least one bearing (5). There is an eccentric journal (6) on the end of the shaft inside the impeller. The journal rotates in an orbital journal bearing (7). The orbital journal bearing moves in a circle within an eccentric bearing 14 on the impeller, driving the impeller. The orbital bearing tightly encloses the journal. A flexible component (9) prevents the orbital bearing from rotating in, and seals it off from, the housing.
