摘要： PROBLEM TO BE SOLVED: To lubricate a sliding surface of a boss and a drive bush, sliding surface of an eccentric drive pin and the drive bush, etc., by drilling a radial direction through hole, connecting the inside/outside of a boss, in the boss of a turn scroll to be opposed to a turn side key of an Oldham's link. SOLUTION: When a turn scroll 2 makes a turning motion of revolution around, a turn side key 63 of an Oldham's link 6 is reciprocated in an arrow direction A in a key groove 66, and a ring 61 is also reciprocated in the arrow direction A. In this way, gas containing a mist of lubricating oil is energized by the ring 61, to pass a through hole 70, and advanced to the inside of a boss 23. Lubricating oil, advanced into an internal peripheral side of the key groove 66 during the time the turn side key 63 is positioned in the outward, in the case of moving the turn side key 63 in a centripetal direction, is press advanced by the internal peripheral side end, and the lubricating oil passes through the key groove 66 and the through hole 70 continued to its internal peripheral end, to be advanced into the inside of the boss 23. In this way, an internal surface of the boss 23, external surface of a drive bush 32 and a turn bearing 34 interposed therebetween, and a sliding surface of a slide hole 33 and an eccentric drive pin 31 are lubricated.

摘要： PROBLEM TO BE SOLVED: To lubricate a subbearing by a mist of lubricating oil by providing a gas suction port into a housing in its one end surface and in a position opposed to an internal circumferential side space of a stator coil in an electric motor. SOLUTION: An internal circumferential side space 60, surrounded by a coil Mb1 of a stator Mb in an electric motor M, is formed, and a gas suction part 61 is provided so as to be opposed to the internal circumferential side space 60 in a right end face of a housing 4. When a motor-driven compressor is operated, gas flows in the internal circumferential side space 60 from the gas suction port 61 inverted here, a mist of lubricating oil contained in this gas is separated to lubricate a subbearing 51. A suction fitting block is tightened here by a bolt 65 to the right end face of the housing 4. This lubricating oil, according to rotating a rotary shear, is sucked to a supply oil hole from its one end opening, and the oil, after energized in a process passing in the supply oil hole, is supplied to the subbearing 51 from the other end opening, with the subbearing lubricated.

摘要： PROBLEM TO BE SOLVED: To easily and quickly match the phase of a stator to the phase of a rotor in a motor-driven compressor in which the phase of the stator at a DC motor is matched to the phase of the rotor in a state that the DC motor and a compression mechanism have been installed inside a housing and in which the rotor is magnetized. SOLUTION: An alignment mark 60 is placed on the shaft end of a rotary shaft 3. A through hole 61 which is passed through to the outside is made in a part which is faced with the shaft end of the rotary shaft 3 in a housing 4. When a rotor Ma is magnetized, the phase of a stator Mb is matched to the phase of the rotor Ma by making use of the hole 61 and the alignment mark 60.

摘要： PROBLEM TO BE SOLVED: To provide a scroll type compressor that can positively secure engagement of a bent piece without causing the enlargement of a thrust receiving member and prevent the break of the bent piece.
SOLUTION: The thrust receiving member 11b is formed with a chamfer 11b2 continuously with a cutout 11b1 toward the center axis side of a thrust sliding bearing 100 rather than the cutout 11b1. Each bent piece 101 is constituted to dispose a bend starting portion 101a in a position corresponding to the position of the chamfer 11b2 from the cross-sectional view including the center axis and to set the curvature to 1.25mm or more.
