Claim:
1. A scroll compressor, comprising: a. a pair of scrolls forming at least one compression chamber with a peripheral suction port and a center discharge port, wherein an orbiting one of the pair of scrolls rotates relative to a stationary one of the pair of scrolls to move gas pockets in a flow direction from the peripheral suction port towards the center discharge port; and b. a compressor discharge chamber in series with and following the center discharge port; and c. a shunt pulsation trap apparatus comprising a pulsation trap chamber adjacent to said compression chamber, at least one pulsation dampener positioned within the pulsation trap chamber, at least one trap inlet branching off from said compression chamber before said discharge port in said flow direction and connecting said compression chamber to said pulsation trap chamber so that at least a portion of said compression chamber and said pulsation trap chamber are arranged in parallel, and at least one trap outlet connecting said pulsation trap chamber to said compressor discharge port, wherein said scroll compressor achieves gas pulsation and NVH reduction at said pulsation trap chamber and improving compressor off-design efficiency.
