摘要： A scroll compressor includes an orbital drive mechanism for causing orbiting of an orbiting scroll relative to a stationary scroll. The orbiting scroll is formed with a generally cylindrical boss extending in a direction away from the stationary scroll. The orbital drive mechanism includes a main shaft rotatably supported by a compressor housing, an eccentric shaft extending from one end face of the main shaft and having a longitudinal axis parallel to, but offset laterally from a longitudinal axis of the main shaft, and an eccentric bush having a socket inserted rotatably into the cylindrical boss. The eccentric shaft, engaged in the socket, is of a non-circular cross-section having short and long axes perpendicular to each other. The eccentric shaft has rounded opposite apexes lying on the long axis thereof to define first and second rounded side faces, while the socket has a first inner wall portion of a smaller curvature confronting the first rounded side face of the eccentric shaft and a second inner wall portion of a greater curvature confronting the second rounded side face of the eccentric shaft. The eccentric shaft is spaced a predetermined distance from inner wall portions of the socket in the direction in which the short axis of the eccentric shaft extends so that the eccentric bush can swing relative to the eccentric shaft about a center of curvature of the first rounded side face of the eccentric shaft, thus varying the orbiting radius.

摘要： A linear compressor comprises a cylinder 10, a piston 20, a linear motor comprising a movable member 40 as well as a stationary member 50, a piston body 28, a discharge mechanism 60, a spring mechanism 70, a vessel 80, a supporting mechanism 90 and the like. A cylindrical holding member 41 is contact with a flange 24 connected to the piston and supported concentrically with the piston 20. A permanent magnet 42 is sandwiched between the cylindrical holding member 41 and a cylindrical body 43. Cylindrical inner yoke 51 and outer yoke 52 of the stationary member 50 are fixed to the cylinder 10, and held concentrically with the piston 20. With the above structure, the movable 40 is smoothly moved together with the piston 20, and a fine gap between the movable member 40 and the stationary member 50 is always maintained stationary. Further, since the linear motor is in contact with the piston 20, the overall length of the linear compressor is shortened, and the linear compressor is reduced in size. Therefore, it is possible to easily mount the movable member to the piston with high precision, and it is possible to easily mount the permanent magnet of the movable member with high precision.

摘要： A linear compressor includes a cylinder supported in a hermetic vessel by a support mechanism. A piston is supported concentrically with the cylinder such that the piston can move in an axial direction of the cylinder. A compression chamber is formed between the cylinder and the piston. A linear motor portion has a moving member connected to the piston through a holding member. A stator is fixed to the cylinder to form a magnetic path between the stator and the moving member. The linear motor portion generates thrust for moving the piston in the axial direction. A sensor detects a displacement of the axial length center of the moving member and a DC bias current is fed to the linear motor to align the axial length of the moving member and the axial length of the stator with each other at the time of operation.
