摘要： PURPOSE:To shorten the total length of a closed housing by decreasing a protruding amount in at least a part corresponding to a glass sealed terminal of an end coil so as to partition a space for receiving the glass sealed terminal between a compression mechanism and an electric motor. CONSTITUTION:In the interior of a closed housing 8, a scroll type compression mechanism C and an electric motor M are arranged respectively in the upper and lower parts and connected associated with each other through a rotary shaft 5. A glass sealed terminal 30 is set up in a position corresponding to a space between the compression mechanism C and the electric motor M in an external peripheral surface side of the closed housing 8 and electrically connected to an upper part end coil Mb1 of a stator Mb in the electric motor M through a lead wire 31. In the above constitution, by bending a part of the upper part end coil Mb1, corresponding to the glass sealed terminal 30, toward the inside, a protruding amount of that part, that is, vertical directional dimension is decreased.

摘要： PURPOSE:To prevent a vane from jumping up and restrain occurrence of noise and seizure, by forming the high pressure side face, including the front end part, of a vane from a material which is excellent in slidability and seizure resistance, and by forming the lower pressure side face from a material which has a low friction coefficient and which is excellent in a high wear resistance. CONSTITUTION:A vane 30 is slidably fitted in a slot 31 in a cylinder 7, and the front end of the vane 30 is made in slidable-contact with the outer peripheral surface of a rotor 6. In this arrangement, the side face, including the front end part, of the vane 30 on the compression chamber 14 side, is formed from a material 30A such as carbon or the like, which is excellent in a slidability and seizure resistance. Further, the side surface of the vane 30 on the suction chamber 13 side is formed from a tool steel material 30B, such as SKH51 or the like, which has a small friction coefficient and which is excellent in wear- resistance. When the vane 30 is extended from and retracted into the slot 31, the materials 30A, 30B are made into slidable contact with the side walls of the slot 31. Thereby it is possible to prevent the vane 30 from jumping up and to restrain occurrence of noise and seizure.

摘要： PROBLEM TO BE SOLVED: To secure guarantee of proper operation by protecting electric parts from ambient environment, reduce the number of parts and the assembly man-hours, improve ease of maintenance, and efficiently cool heating elements.
SOLUTION: An electric motor housing 41 forms an outer shell of a compressor body including a compressor part 44 sucking refrigerant therein and compressing it. A power transistor 58, an inverter control box 56, and a smoothing capacitor 64 are separately attached to an peripheral surface of the electric motor housing 41. The power transistor 58 supplies drive power as three-phase power to a compressor part 44. The inverter box 56 has a printed board 57 on which an element for controlling a power transistor 58 is mounted. The smoothing capacitor 64 stabilizes the drive power supplied to the electric motor part 45. The power transistor 58 and smoothing capacitor 64 are closely and tightly fixed to the electric motor housing 41. When the operation of a refrigeration cycle is stopped and an ambient temperature of electric parts constituted of the inverter box 56 and smoothing capacitor 64 is a predetermined temperature, cooling operation for operating the compressor part 44 is performed.

摘要： PROBLEM TO BE SOLVED: To simplify an electric circuit, and reduce a cost by arranging a sensor in an engine room so as to detect an order or white smoke based on a slip of a belt, and arranging a controller to disengage a clutch when this sensor detects the ordor or the white smoke. SOLUTION: A clutch 5 is disengaged by a command from a controller 21 when a sensor 20 detects an ordor or white smoke based on a slip of a belt 4 by arranging the sensor 20 in an engine room 1. Here, the ordor or white smoke is generated since the belt 4 slips when a compressor 6 is abnormally stopped by a lock. The compressor 6 is stopped by immediately disengaging the clutch 5 by a command from the controller 21 when the signal is inputted to the controller 21 after the sensor 20 detects this ordor or the white smoke. Therefore, rupture of the belt is prevented, and an electric circuit is also simplified to reduce a cost.

摘要： PROBLEM TO BE SOLVED: To prevent a root part of a parting preventive pin from disrupting by fatigue by forming the parting preventive pin in a stepped shape, and forming a diameter of its root part as a large diameter. SOLUTION: It is erected by pressing a parting preventive pin 51 in an inside end surface of an inside end large diameter part 7a of a rotary shaft 7. This parting preventive pin 51 is loosely movably penetrated into a hole 50 bored in a balance weight 27, and the inner peripheral edges of plural presser springs 52 are locked on a collar 54 formed on its tip. The balance weight 27 is restrained from parting from an inside end surface of the inside end large diameter part 7a of the rotary shaft 7 by slidingly contacting the outer peripheral edges of these presser springs 54 with an upper surface of the balance weight 27. Its root part 53 generating maximum stress is also formed as a larger diameter than a tip part by forming the parting preventive pin 51 in a stepped shape. A recessed place 55 to which the large diameter root part 53 of the parting preventive pin 51 can be fitted, is formed in a lengthwise directional root part of the hole 50.

摘要： PROBLEM TO BE SOLVED: To prevent relief of a balance weight by interposing an abrasion preventive member between a head part lower surface of a relief preventive pin a head end of which is engaged with an inner end large diametrical part of a rotary shaft by passing through a hole drilled on the balance weight free to move with a playand an upper surface of the balance weight. SOLUTION: A revolving scroll is slantly rotated by receiving a slantly rotating moment in accordance with gas pressure at the time of driving a scroll type compressor, and accordingly, a balance weight 27 is slantly rotated and relieved from an end surface of an inner end large diametrical part 7a of a rotary shaft 7. A relief preventive pin 40 to pass through a hole 38 drilled on the balance weight 27 free to move with a play is provided so as to prevent this relief, its head end is press fitted and fixed in the inner end large diametrical part 7a, and a lower surface of a head part 40a of this preventive pin 40 is made to slide on an upper surface of the balance weight 27. Thereafter, an abrasion preventive member 42 is interposed between the lower surface of the head part 40a and the upper surface of the balance weight 27 so as to prevent abrasion of the upper surface of the balance weight 27.

摘要： PROBLEM TO BE SOLVED: To heighten slidableness so as to prevent seizure or the like by applying Su plating to at least the side faces of turning side and fixed side keys of an Oldham' s link guaranteeing revolving motion while impeding the rotation of a turning scroll. SOLUTION: In case of a housing, a fixed scroll and a turning scroll 14 in a scroll type compressor being formed of an aluminium alloy and an Oldham' s link 26 being formed of an iron ally, slidableness between a turning side key 26a and a fixed side key 26b of the Oldham's link 26, and key grooves 41, 43 is bad. In order to improve on this slidableness, Su plating is applied to at least the side faces (ranges with intersecting oblique lines) of the turning side key 26a and fixed side key 26b of the Oldham's link 26. Conformability of sliding parts is therefore improved to heighten slidableness and to prevent the generation of galling, seizure, and the like. Slidableness can also be improved by providing a large number of fine grooves in at least the side faces of the turning side key 26a and fixed side key 26b of the Oldham's link 26.
