摘要： A self-rotation blocking mechanism in a scroll compressor having a movable scroll member and fixed scroll member fixed to a casing. The mechanism is constructed of circumferentially spaced opposing pairs of pins 9 and 10, which are connected to an end plate 12 of the movable scroll member 2 and a faced end wall of the casing 4, respectively, and which are in a side-by-side contacting relationship. The circumferential arrangement of the pins is such that, at every angular position of the movable scroll member, there exists at least one pair of the pins which generates a force in a direction opposite to a self-rotating torque applied to the movable scroll member caused by the compression reaction force. A locally concentrated arrangement of the pairs of the pins for generating such a force can be employed at the angular position which produces a larger value of self-rotating torque. Furthermore, the diameters of the pins are such that one half of the sum of the diameters is equal to or smaller than the radius of the orbital movement of the movable scroll member.

摘要： Ein Kompressor (1) der Drehzylinderbauart hat: einen Zylinder (21), der im Inneren eines Gehäuses (10) drehbar angeordnet ist; und einen Rotor (22a, 22b), der in eine zylindrische Rohrform geformt ist und in einem Inneren des Zylinders angeordnet ist, während der Rotor um eine exzentrische Achse drehbar ist, die exzentrisch zu einer Drehmittelachse des Zylinders ist. Des Weiteren hat der Kompressor der Drehzylinderbauart ein Teilungsbauteil (23a, 23b), das eine Arbeitskammer, die zwischen einer Außenumfangsfläche (225a, 225b) des Rotors und einer Innenumfangsfläche (21a) des Zylinders ausgebildet ist, in einen Ansaugraum, der ein Fluid ansaugt, und einen Kompressionsraum unterteilt, der das Fluid komprimiert. Der Rotor ist als einer von wenigstens einem Rotor in dem Inneren des Zylinders vorgesehen. Der Rotor und der Zylinder sind derart gestaltet, dass, wenn ein Druck des Fluids in dem Kompressionsraum gleich wie oder größer als ein vorbestimmter Referenzdruck ist, eine Kontaktspannung, die an einem angrenzenden Abschnitt zwischen der Außenumfangsfläche (225a, 225b) des Rotors und der Innenumfangsfläche (21a) des Zylinders ausgeübt wird, im Vergleich zu einem Fall erhöht ist, in dem der Druck des Fluids in dem Kompressionsraum kleiner als der vorbestimmte Referenzdruck ist.

摘要： In a manufacturing method of a heat exchanger including a core portion (11) having a plurality of tubes (13) and a plurality of radiation fins (14) connected to surfaces of the tubes, and a tank portion (12) communicating with the tubes, a preheating step, a brazing step, a gradual cooling step and a cooling step are performed in this order. In the preheating step, temperature of the tank portion having a large heat capacity is increased earlier than that of the core portion having a small heat capacity. Therefore, the temperature of the tank portion is rapidly increased, and the temperature of the core portion is obediently increased in accordance with the temperature increase of the tank portion.

摘要： For integrally bonding a first member and a second member made of copper or a copper alloy by brazing, a paste brazing material composed essentially of copper (Cu), tin (Sn), nickel (Ni) and phosphorus (P) is beforehand applied to at least one of the first and second members. A base material is exposed at the whole or a part of a contact portion between the first and second members. Thereafter, the first and second members are assembled at a predetermined position, and heated at a temperature in a range of 600° C.-800° C. within a reducing atmosphere furnace. By the brazing method, an oxide film on the surface of the base material can be sufficiently removed, so that the paste brazing material can smoothly flow on the surface at the contact portion.

摘要： Ein Kompressor vom Typ mit einem sich drehenden Zylinder umfasst Folgendes: einen Zylinder (21), der eine zylindrische Gestalt aufweist und sich um eine Mittelachse (C1) herum dreht; einen ersten Rotor (22a) und einen zweiten Rotor (22b), die jeweils eine zylindrische Gestalt aufweisen und sich um eine exzentrische Achse (C2) herum drehen, die exzentrisch zu der Mittelachse (C1) des Zylinders (21) ist; eine Welle (24); einen ersten Flügel (23a); und einen zweiten Flügel (23b). Der erste Flügel (23a) ist gleitend verschiebbar an einem ersten Nut-Abschnitt (222a) angebracht, der in dem ersten Rotor (22a) definiert ist, um eine erste Kompressionskammer (Va) zu definieren. Der zweite Flügel (23b) ist gleitend verschiebbar an einem zweiten Nut-Abschnitt (222b) angebracht, der in dem zweiten Rotor (22b) definiert ist, um eine zweite Kompressionskammer (Vb) zu definieren. Der erste Rotor (22a) und der zweite Rotor (22b) sind in einer Richtung angeordnet, in der sich die Mittelachse (C1) des Zylinders (21) erstreckt.
