<p>PROBLEM TO BE SOLVED: To provide a bidirectional rotation scroll type fluid machine for reducing the size and costs of a boss part while enhancing cooling effects in the vicinity of a discharge hole becoming a high temperature.SOLUTION: A housing 12 incorporates a driving scroll body 28 and a driven scroll body 30, and both scroll bodies 28, 30 are rotatably supported by ball bearings 54, 56, 60. At an end face 12a of the housing 12, a boss part 50 is formed which incorporates a discharge cylinder 46 forming a discharge path for compressed gas and the ball bearing 56 rotatably supporting the discharge cylinder 46. Air inlets 62a-62c are provided in the end face 12a, a number of centrifugal blades 66 are formed on the end plate back face of the driven scroll body 30, and an air outlet 63 is provided in the housing 12 on the radial outside of the centrifugal blades 66. With the rotation of the driven scroll body 30, cool air w is sucked from the air inlets 62a-62c, passed among the centrifugal blades 66, and released from an air outlet 64.</p> |
