Title:
GAS COMPRESSOR
Document Type and Number:
Japanese Patent JP2016205203
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To efficiently separate an oil component in a compressed gas by a centrifugal separation type oil separator even if a flow speed of the compressed gas is low.SOLUTION: A swirl flow of a compressed refrigerant 13 which flows into an oil separation chamber 7f from a flow-in port 7g of an oil separator 7e is made to collide with a fin 7q of a cylinder member 7k which extends on a route of the swirl flow, and the cylinder member 7k is rotated by a rotation thrust force which is obtained by the fin 7q from the swirl flow. A lubricant 11 is separated from the swirl flow of the compressed refrigerant 13 which has collided with the fin 7q by a centrifugal force, and made to adhere on an internal peripheral wall 7h of the oil separator 7f. Furthermore, the lubricant 11 in the compressed refrigerant 13 which has adhered on a peripheral face 7n of the cylinder member 7k, an internal peripheral edge of a communication hole 7p and an internal peripheral face of the cylinder member 7k is scattered to the outside of the cylinder member 7k by the centrifugal force which is generated by the rotation of the cylinder member 7k, and made to adhere on the internal peripheral wall 7h of the oil separation chamber 7f. The lubricant 11 which has adhered on the internal peripheral wall 7h of the oil separation chamber 7f is made to drip to an oil sump 7d of a compression chamber 7a.SELECTED DRAWING: Figure 3
