  • Publication number: 20020071774
    Abstract: Disclosed herewith is a compressor with mufflers. The compressor comprises a drive unit, a compression unit, at least a pair of exhaust mufflers, a coolant exhaust conduit, and a connecting conduit. The drive unit generates power. The compression unit sucks, compresses and exhausts coolant using power transmitted from the drive unit. The exhaust mufflers temporarily store coolant exhausted from the compressing unit. The coolant exhaust conduit is connected to one of the exhaust mufflers to guide the exhaust of coolant to the outside. The connecting conduit connects the exhaust mufflers to each other to cancel out noises during the recombination of divided coolant in one of the exhaust mufflers.
