Patent ID: 6872063

Claim:
A scroll type compressor comprising: a housing; a fixed scroll member fixed in the housing, the fixed scroll member having a fixed base plate and a fixed spiral wall that extends from the fixed base plate; a movable scroll member placed in the housing, the movable scroll member having a movable base plate and a movable spiral wall that extends from the movable base plate, the movable spiral wall being engaged with the fixed spiral wall, a compression chamber being defined between the movable spiral wall and the fixed spiral wall, the compression chamber being gradually reduced in volume as refrigerant in the compression chamber is gradually compressed and is moved toward a center side of the spiral walls by orbital movement of the movable scroll member relative to the fixed scroll member; an elastic member formed in an annular and planar shape, the elastic member being fixed in the housing on a side of a back surface of the movable base plate so as to slidably contact the back surface of the movable base plate at a sliding region of the elastic member; and a facing wall provided on a side opposite to a side of the movable scroll member with respect to the elastic member, wherein a first space is formed between the elastic member and the facing wall for allowing the elastic member to be elastically deformed, the elastic member being elastically deformed toward the facing wall by press-contacting the movable scroll member, whereby the movable scroll member is urged toward the fixed scroll member.
