Abstract
Disclosed are a compressor and a refrigerating machine having the same, wherein a bearing member (ball bearing) is installed between both thrust bearing surfaces and an elastic member is disposed between the bearing member and at least one of the thrust bearing surfaces so as to allow a rolling contact between the ball bearing and the thrust bearing surface or a washer, thereby reducing a frictional loss at the thrust bearing surface and enhancing the performance of the compressor.
Claims18
A compressor comprising:
- a cylinder block having a cylinder defining a compression space, and having a first thrust bearing surface at one side of the cylinder;
- a crank shaft having a second thrust bearing surface supported at the first thrust bearing surface, and performing a rotating motion with respect to the cylinder block, the crank shaft being coupled to a piston inserted into the cylinder to transfer a driving force for a reciprocating motion of the piston;
- a bearing member disposed between the first thrust bearing surface and the second thrust bearing surface;
- and
- an elastic member disposed between the bearing member and the first thrust bearing surface or between the bearing member and the second thrust bearing surface to support the bearing member in a thrust direction.
2 more elements
A compressor comprising:
- a ball bearing disposed between both thrust bearing surfaces for supporting a crank shaft in a thrust direction, the ball bearing functioning as a bearing;
- and
- an elastic member provided to have elasticity with respect to the bal bearing in the thrust direction to support the ball bearing.
