Patent ID: 7473084

Claim:
An oil-cooled screw compressor adapted to compress a gaseous matter while being cooled by an oil to be separated from the gaseous matter, and adapted be connected onto a base, comprising; a compressor body including a pair of a male rotor and a female rotor, a motor including a stator and a motor rotor supported by a bearing at an intake side of the pair of male and female rotors and connected to one of the male and female rotors at the intake side of the pair of male and female rotors to drive rotationally the one of the male and female rotors, an oil separator container for gathering the oil from a mixture of the gaseous matter and the oil after the mixture is discharged from the pair of the male and female rotors, wherein the oil separator container has a vertical longitudinal axis arranged vertically under the compressor body so that the compressor body, the motor and the oil separator form one of an L-shape and a T-shape, and a vibration absorbing member through which the oil separator container is connected onto the base with an elasticity of the vibration absorbing member, wherein the vibration absorbing member includes first and second parts distant from each other in the axial direction, the first part is closer to the motor than the second part in the axial direction, and a spring constant of the elasticity of the first part is greater than a spring constant of the elasticity of the second part.
