Abstract: An orbiting scroll of a scroll compressor includes a platter wall having a first face including a spiral structure projecting therefrom, a second face having a coupling structure configured to couple the orbiting scroll to a drive mechanism of the scroll compressor, and a circumferential surface connecting the first face to the second face in an axial direction of the platter wall. The orbiting scroll includes a mass reduction feature provided as an inwardly indented channel formed in the circumferential surface. The channel is further configured to form a retaining feature for retaining a rim of a mask during a process of coating the spiral structure of the first face with a surface coating.

Abstract: A fixed scroll compressor body includes a scroll compressor body casting. The casting has a central body portion having a plate-like base with a spiral scroll rib projecting from the base at a right angle thereto. The spiral scroll rib includes a volume between the spiraled ribs for the compressing of refrigerant. The spiral scroll rib spirals from a central region of the plate-like base to an outer wall of the central body portion. The casting further includes a first inward-protruding portion that protrudes from the outer wall into the volume. A distance that the first inward-protruding portion protrudes into the volume is greater than a thickness of the first inward-protruding portion such that removal of the first inward-protruding portion results in a first intake opening in the outer wall. The first intake opening provides a path for a flow of refrigerant into the volume.

Abstract: A microsystem for converting pressure difference in fluid into mechanical displacement includes input and output nozzles, two interleaved parts, one of which is mobile part, between which the fluid flows. During displacement, the parts define an expanding fluid pocket that moves from the input nozzle to the output nozzle. The micro-system also includes top and bottom planes between which the mobile part is mounted for displacement relative to each plane, an overhanging distal portion along which the fluid flows, and a proximal portion mechanically linked to a plane via a link allowing only longitudinal translation of the proximal portion, and a reinforcement including a first side fastened to one of the planes and, a second side that is either fastened to or in sliding contact with the overhanging distal portion of the mobile part to limit its deformation in a transverse direction perpendicular to the longitudinal direction.
