Abstract
A scroll compressor that simplifies the structure of a valve and decrease the size of the entire compressor includes a casing having a first chamber into which a fluid is sucked and a second chamber at which compressed fluid is discharged, a driving unit housed inside the casing to generate a driving force, a compressing unit having a fixed scroll and an orbiting scroll connected to the driving unit by a rotational shaft to compress and discharge the fluid when the driving unit is operated. A valve assembly is rotatively installed to the upper surface of the fixed scroll, opening/closing a discharge hole at which the compressed fluid is discharged and opening/closing a passage connecting the first chamber and the second chamber.

A scroll compressor, comprising:
- a casing having a hermetically sealed certain space divided into a first chamber at which a fluid is sucked and a second chamber at which a compressed fluid is discharged;
- a driving unit housed inside the casing and generating a driving force;
- a compressing unit including a fixed scroll and an orbiting scroll connected to the driving unit by a rotational shaft in order to compress and discharge the fluid when the driving unit is operated;
- and
- a valve assembly rotatively installed to the upper surface of the fixed scroll, opening/closing a discharge hole at which the compressed fluid is discharged and opening/closing a passage connecting the first chamber and the second chamber;
- wherein the valve assembly includes a rod part hinge-connected to the fixed scroll and curved in two directions centering around a hinge-connected point;
- a hinge part formed between the rod part and the upper surface of the fixed scroll and supporting the rod part rotatively;
- a first valve part formed at the end of the rod part and opening/closing the discharge hole;
- and a second valve part formed at the other end of the rod part and opening/closing the passage.
