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.

1. 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. 2. The scroll compressor of claim 1, wherein an inner diameter of the passage is smaller than an inner diameter of the discharge hole. 3. The scroll compressor of claim 1, wherein the rod part is rotatively installed to the upper surface of the fixed scroll by the hinge part and has a plate shape curved at a certain angle in two directions centering around the hinge part. 4. The scroll compressor of claim 1, wherein the hinge part is constructed with a hinge bracket perpendicularly projected from the upper surface of the fixed scroll and having a hinge hole at which a hinge pin is inserted and a hinge protrusion upwardly projected from the curved portion of the rod part and having a hinge hole at which the hinge pin is inserted. 5. The scroll compressor of claim 1, wherein the first valve part is extended from one end of the rod part and is formed as a circular flat plate shape in order to open/close the discharge hole. 6. The scroll compressor of claim 5, wherein the first valve part is formed so as to have a diameter greater than an inner diameter of the discharge hole. 7. The scroll compressor of claim 1, wherein the first valve part is formed so as to have a diameter greater than an inner diameter of the discharge hole. 8. The scroll compressor of claim 1, wherein the second valve part is extended from the other end of the rod part and is formed as a circular flat plate shape in order to open/close the passage. 9. The scroll compressor of claim 8, wherein the second valve part is formed so as to have a diameter greater than an inner diameter of the passage. 10. The scroll compressor of claim 1, wherein the second valve part is formed so as to have a diameter greater than an inner diameter of the passage.
