PROBLEM TO BE SOLVED: To improve performance and reliability of scroll fluid machinery by providing a plural number of ports for refrigerant injection on the scroll fluid machinery having a non-symmetrical spiral body. SOLUTION: An injection pipe 7 is connected to a fixed scroll 2 through a connector 8a. The fixed scroll 2 has a recessed part 2b to receive the connector 8a and first and second ports 2c1, 2c2 to be communicated over to a space in the recessed part 2b. A set of compression chambers 6, 6 is formed between the fixed scroll 2 and a movable scroll 3. The first and second ports 2c1, 2c2 respectively open to these compression chambers 6, 6.
