Abstract: A scroll compressor includes a refrigerant suction pipe coupled to a discharge cover or a fixed scroll through a casing in a radial direction, a suction passage communicating the refrigerant suction pipe with a compression chamber, and a suction passage opening and closing valve disposed inside the suction passage to be slidable in an axial direction so as to selectively open or close the suction passage. Accordingly, when the compressor is stopped, oil or refrigerant in the casing can be restricted quickly so as not to flow back to the refrigerant suction pipe through a compression unit.

Abstract: A scroll compressor is provided that may include an orbiting scroll having an orbiting wrap, and which performs an orbiting motion; and a fixed scroll having a fixed wrap to form a compression chamber including a suction chamber, an intermediate pressure chamber, and a discharge chamber, by being engaged with the orbiting wrap. In a state in which the orbiting scroll and the fixed scroll are concentric with each other, when a distance between the orbiting wrap and the fixed wrap is defined as an orbiting radius, there exists an offset section having an interval larger than the orbiting radius, between a side surface of the orbiting wrap and a side surface of the fixed wrap which faces the orbiting wrap. With such a configuration, even if the fixed scroll or the orbiting scroll is transformed due to thermal expansion, interference between the fixed wrap and the orbiting wrap at a portion having a large transformation amount may be prevented. This may prevent a frictional loss or abrasion between the fixed wrap and the orbiting wrap. Further, this may restrict or minimize a gap between the fixed wrap and the orbiting wrap at an opposite side to the suction chamber, resulting in enhanced compression efficiency.
