Title: Scroll compressor
Inventor: UCHIDA KAZUHIDE
IPC: F04C29/02
Filed: 1994-01-12
Abstract: PURPOSE:To prevent abrasion of a blade and loss of driving force by fitting sliding plates which are spirally formed in the same manner as the blade along an inner or outer peripheral surface of at least one of the blades, and by saving trouble and a manufacturing cost. CONSTITUTION:A blade of a movable scroll member is meshed with a blade 32 of a fixed scroll member 3. Inner and outer peripheral surfaces of the blades are slid when a compressor is iperated. Coolant is suctioned in an operation chamber formed by the blades for compression and discharging. Since the inner and outer peripheral surfaces of the blade 32 of the fixed scroll member 3 are coated with iron sliding plates 4, abrasion does not occur at the blade of the movable scroll which is slid on the surfaces of the sliding plates 4 having small abrasion resistance. Loss of rotational driving force is also prevented because the frictional resistance is small. Oil introduction ports 43 are formed on the sliding plates 43, so that an oil film is formed between the sliding plate 4 and the blade 32. Thus even when horizontal dislocation occurs between the sliding plates at the surface of the blade, the blade is not be abraded.

Filed: 1979-02-09
Abstract: PURPOSE: To rotate a rotor containing a permanent magnet due to temperature change in a thermal motor by providing a stator of the motor with metal which reversibly alters its readily magnetizing axis due to the temperature change.  
     CONSTITUTION: A pair of permanent magnets 1 are held around a stator 3 made of metal which alters the readily magnetizing axis according to temperature change such as, for example, NdCo 5 , and a rotor 2 is rotatably disposed. An electric heating element 6 is disposed on the upper surface of the stator 3, and energized to alternatively heat and cool the stator 3. Then, the direction of its magnetic pole of the stator 3 is altered. When the rotor 2 holding the permanent magnets 1 is so controlled as to restrict its rotating direction in one direction, the rotor 2 will roate in one direction. Thus, the temperature change can be converted to a rotary energy to provide a simple mechanism with low weight in a thermal motor.
