Abstract
A screw compressor includes a casing, a screw rotor, a discharge passage, and at least one muffler space. The casing includes a cylindrically-shaped cylinder, a main body surrounding a vicinity of the cylinder, and a high-pressure fluid passage provided between the main body and the cylinder. The screw rotor includes a plurality of helical grooves. The screw rotor is inserted into the cylinder to define fluid chambers. A fluid is sucked into the fluid chambers to compress the fluid. The discharge passage is disposed in the casing. The discharge passage guides the fluid that has been discharged from the fluid chambers to the high-pressure fluid passage. The at least one muffler space is disposed in the casing. The at least one muffler space communicates with the discharge passage so as to reduce a pressure fluctuation of the fluid flowing from the discharge passage to the high-pressure fluid passage.
