Scroll compressor

A scroll compressor comprising:

• a housing including a suction chamber into which fluid is sucked;
• a driving shaft provided in the housing, the driving shaft being rotatable around a driving axis;
• a fixed scroll fixed to the housing;
• and
• a movable scroll provided in the housing, the movable scroll being connected to the driving shaft,
• the housing having a fixed block that is located between the suction chamber and a set of the fixed scroll and the movable scroll, and through which the driving shaft is rotatably inserted,
• the movable scroll and the fixed block being coupled to each other by an anti-rotation mechanism that prevents the movable scroll from rotating on an axis of the movable scroll, and
• the fluid being compressed in a compression chamber by the movable scroll orbiting relative to the fixed scroll, the compression chamber being formed between the fixed scroll and the movable scroll, wherein
• the fixed block has a block side suction passage that communicates with the suction chamber and through which the fluid in the suction chamber flows toward the fixed scroll,
• the fixed scroll has a scroll side suction passage that is recessed in a direction in which the driving axis extends, that faces the block side suction passage in the direction in which the driving axis extends and communicates with the block side suction passage, and through which the fluid is sucked from the block side suction passage toward the compression chamber,
• the block side suction passage consists of a first block side suction passage, a second block side suction passage, and a third block side suction passage that are arranged away from each other in a rotational direction of the driving shaft,
• the scroll side suction passage consists of a first scroll side suction passage that communicates with the first block side suction passage, a second scroll side suction passage that communicates with the second block side suction passage, and a third scroll side suction passage that communicates with the third block side suction passage,
• each of the first block side suction passage, the second block side suction passage, the first scroll side suction passage, and the second scroll side suction passage consists of a single passage,
• the first scroll side suction passage and the second scroll side suction passage are disposed opposite to each other across the driving axis, and
• the third scroll side suction passage is disposed at a position where pressure loss of the fluid that is sucked from the third scroll side suction passage toward the compression chamber is greater than pressure loss of each of the fluid that is sucked from the first scroll side suction passage toward the compression chamber and the fluid that is sucked from the second scroll side suction passage toward the compression chamber.
