Patent ID: 7040883

Claim:
A vane supporting apparatus for a hermetic compressor, the hermetic compressor comprising a sealed casing, a motor device unit coupled on an inner upper part of the casing and configured to generate driving power, a cylinder fixedly coupled to a lower part of the casing, a first bearing plate and a second bearing plate fixed on upper and lower surfaces of the cylinder so as to form an inner space of the cylinder together with the cylinder, a rotating shaft coupled to a rotor of the motor device unit and penetrating the respective bearing plates, a dividing plate coupled to the rotating shaft in the inner space of the cylinder for dividing the inner space into a plurality of sealed spaces, and a plurality of vanes reciprocating along an axial line direction and contacted to both surfaces of the dividing plate when the rotating shaft is rotated so as to convert the respective sealed spaces into a suction area and a compression area, the vane supporting apparatus comprising: at least one torsion coil spring having one end contacted to one of the respective bearing plates, the other end contacted to one of the respective vanes, and an intermediate part formed of a winding portion configured to elastically support the respective vane; and at least one supporting member coupled to an outer side surface of the respective bearing plate so that the at least one torsion coil spring is fixedly supported by the respective outer side surface of the respective bearing plate, wherein the winding portion of the at least one torsion coil spring is inserted onto and supported by a supporting protrusive portion that extends from the at least one supporting member.
