PROBLEM TO BE SOLVED: To provide a scroll-type compressor capable of reducing the pulsation in discharging the compressed fluid. SOLUTION: A spiral fixed scroll tooth 2a projects from a panel board 2b of a fixed scroll 2, and a spiral movable scroll tooth 4a projects from an end plate 4b of a movable scroll 4. The end plate 4a of the movable scroll 4 is provided with a discharge opening 8 for discharging the compressed refrigerant gas. A pressure chamber 16 is formed on the rear side of the end plate 2b. A port 10 communicated with the pressure chamber 16 is mounted on a position opposite to the discharge opening 8 of the end plate 2b.
