  • Patent number: 6808373
    Abstract: Inner peripheral projections are provided on the inner peripheral surface of a wrap portion of an orbiting scroll member, and outer peripheral projections are provided on the outer peripheral surface of the wrap portion. The inner and outer peripheral projections each have an approximately triangular transverse sectional configuration defined by a narrow top of the projection and a pair of concavely arcuate surfaces extending with a wide overall width so that the projections can prevent stress concentration with the concavely arcuate surfaces to increase the mechanical strength and can be readily machined by using a tool, e.g. an end mill. When contacting the mating wrap portion, the narrow tops of the projections are readily crushed or worn. Therefore, the tops of the projections can become fit to the wrap portion without strongly contacting it many times.

  • Patent number: 5934890
    Abstract: Joint guides comprise mutually opposing guide portions formed on a casing and mutually opposing guide portions provided on an orbiting scroll member. A plate spring is integrally attached to a part of each guide portion. Even when a load due to rotational torque from the orbiting scroll member acts on each slider from a loading-side guide portion, resilient force from the plate spring presses a sliding surface of the slider toward a sliding surface of the loading-side guide portion, thereby preventing the formation of a gap between the sliding surface of each slider and a convexly curved portion of the associated plate spring or between the sliding surface of each slider and the sliding surface of the associated guide portion, and thus preventing the occurrence of a rattle.

  • Patent number: 5813843
    Abstract: In the scroll-type fluidic machine according to the present invention, a slider is slidably disposed between a casing and a rear surface of a orbiting scroll member, and a sliding movement of the slider relative to the casing and the orbiting scroll member is regulated to two (X-axis and Y-axis) directions by means of X-axis and Y-axis guides. Balls received in through holes of the slider are formed from material harder than that of the slider and are rollingly contacted with a slide surface of a flange portion of the casing and a slide surface of a rear plate of the orbiting scroll member. The through holes are filled with grease. The balls are adapted to roll smoothly, thereby greatly decreasing frictional resistance between surfaces of the slider and the slide surfaces of the casing and the orbiting scroll member.

  • Patent number: 5803723
    Abstract: A wrap of an orbiting scroll member and a wrap of a fixed scroll member are each provided with a non-rigid surface coating layer having a predetermined thickness. An orbiting radius varying mechanism is provided between a driving shaft and the orbiting scroll member, thereby gradually increasing the orbiting radius of the orbiting scroll member at the initial stage of running, and thus positively allowing the surface coating layers to wear by rubbing against each other. A stopper mechanism is provided between the driving shaft and the orbiting scroll member to regulate the rotation angle of a variable crank relative to the driving shaft to a predetermined rotation angle, thereby preventing the surface coating layers from being excessively worn as the orbiting radius of the orbiting scroll member increases.
