摘要： A performance of a compressor is enhanced and durability of scroll bodies is enhanced by optimizing relief to machining tolerance at a central end part of spiral members for forming the scroll bodies. In a scroll type compressor in which a reinforced portion (for example, a large radius of curvature R) reinforced more than in other root corner portions 5 is provided in a root corner portion 5 at a central end part in which a stress of the two spiral members 10 and 20 is increased, a first relief is formed in a region in which the two spiral members 10 and 20 come into contact with each other where the reinforced portion is applied only to one of the spiral members 10 and 20, and a second relief larger than the first relief is provided in a region in which the two spiral members come into contact with each other at a portion in which the radius of curvature R is provided in both of the two spiral members, thereby reasonably forming reliefs for avoiding interference at the point of contact of two spiral members.

摘要： A method of processing a scroll member having a spiral wrap and an end plate which is conducted by effecting a shaving on at least one side surface of the spiral wrap by a tool while applying to the tool both of an axial small force and an ultrasonic oscillation simultaneously. An apparatus is proposed which comprises a shaving tool having a spiral groove of the same configuration as the spiral wrap, and a cutting edge portion formed on at least one side edge of the groove over the entire length of the side edge. A tool supporting device supports the shaving tool, and a blank supporting device supports a scroll blank such that the scroll blank opposes to the shaving tool. A device is connected to the tool supporting means and is adapted to impart to the tool a pressing force necessary for effecting the shaving, and an ultrasonic oscillation generating device is adapted to impart an ultrasonic oscillation to one of the tool or the blank.

摘要： A pendulum slider pump may include an inner rotor connected via a plurality of pendulums to an outer rotor. The pendulums may be mounted on the outer rotor in an articulated manner, and the pendulums may respectively include a pendulum foot guiding in an associated radial groove arranged in the inner rotor. The radial grooves may each include a groove base and two circumferentially spaced groove walls. The outer rotor, the inner rotor and two pendulums adjacent in a circumferential direction may each delimit a chamber. Each pendulum foot together with the associated groove walls and the groove base may delimit a pendulum foot space. At least one pendulum foot space may be connected to the associated chamber via at least one communication channel. The at least one communication channel may open into the pendulum foot space in a region of the groove base.

摘要： 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.

摘要： Damage of a rotor and a side plate are suppressed with a simple construction to prevent reduction in durability of a vacuum pump. A casing manufacturing method comprises a step (step S2) of disposing a cylinder liner forming a cylinder chamber in a mold, and casting a casing main body integrally with the cylinder liner by using molten metal, and a step (step S3) of processing an intercommunication hole and an exhaust hole so that the intercommunication hole and the exhaust hole penetrate through both the cylinder liner and the casing main body together and intercommunicate with the cylinder chamber.
