Abstract

A body supporting apparatus is provided for motored compressors. The body supporting apparatus includes two coil springs that connect a seat spring of a stator to a seat spring of a lower casing holding the stator thereon, The two coil springs thus stably support the stator on the lower casing. A cylindrical spring guider is set between the two coil springs with an annular support ring formed around the central portion of the internal surface of the guide and supporting the two coil springs on opposite surfaces thereof within the guider. Two coil seat chambers are formed in the cylindrical guider at positions above and under the support ring and communicate with each other through a central opening of the support ring. The two coil springs are movably received within the two coil seas chambers such that the elastic compressive and tensile movement of the two coil springs are axially and stably guided within the associated chambers of the guider without being undesirably moved in a transverse direction. The body supporting apparatus for motored compressors almost completely prevents the stator support coil springs from undesirable movement in a transverse direction, thus preventing a transverse vibration of the stator during an operation of such a motored compressor.

Claims

1. A body supporting apparatus for motored compressors, comprising:

a stator installed on a frame of a motored compressor, said frame having a vibration source;

an elastic member connected to said stator and configured to support the stator;

a fixed support part fixedly installed relative to the stator and configured to support the elastic member; and

a guider installed at a middle portion of the elastic member and configured to guide an elastic movement of the elastic member, the guider having a central opening extending therethrough for receiving the elastic member.

2. The body supporting apparatus according to claim 1, wherein the guider is in the shape of a cylinder.

3. The body supporting apparatus according to claim 2, wherein the elastic member comprises a pair of elastic members, and the guider is positioned between the pair of elastic members.

4. The body supporting apparatus according to claim 3, wherein the guider includes an annular support ring disposed in the opening which divides the opening into an upper chamber and a lower chamber, and wherein the upper chamber receives a lower portion of one of the pair of elastic members and the lower chamber receives an upper portion of the other of the pair of elastic members.

5. The body supporting apparatus as claimed in claim 1, wherein the elastic member comprises a pair of elastic members, and the guider is positioned between the pair of elastic members.

6. The body supporting apparatus as claimed in claim 5, wherein the guider includes an annular support ring disposed in the opening which divides the opening into an upper chamber and a lower chamber, wherein the upper chamber receives a lower portion of one of the pair of elastic members and the lower chamber receives an upper portion of the other of the pair of elastic members.

7. A body supporting apparatus for a motored compressor, comprising:

a stator installed on a frame of a motored compressor, the frame having a vibration source;
