A scroll compressor for compressing fluid, comprising: a first scroll compressor body having a first base , a first scroll rib projecting from the first base , and a discharge port; a second scroll compressor body having a second base and a second scroll rib projecting from the second base , the first and second bases being axially spaced apart with the first and second scroll ribs mutually received in each other to define at least one compression chamber between an intake region and the discharge port , wherein relative movement between the first and second scroll compressor bodies is adapted to compress fluid from the intake region to the discharge port ; and a scroll tip seal projecting axially from the second scroll rib and adapted to sealingly engage the first base for sealing the at least one compression chamber ; means formed into the discharge port for accommodating sweeping movement of the scroll tip seal into a conventional discharge port region to enable scroll tip seal lengthening on the second scroll rib , characterized in that the shape of the discharge port includes an edge portion with a receding region having an inward-facing radius whose center is located outside the perimeter of the discharge port ; and that the receding region with the inward-facing radius enables the length of the scroll tip seal in the vicinity of the discharge port to be greater than it would be in the absence of the receding region with the inward-facing radius, and that the size and location of the inward-facing radius of the discharge port is determined by a seal sweep radius defined by a circular movement of an end of the scroll tip seal , so that an overlap between the scroll tip seal and the discharge port is prevented. a first scroll compressor body having a first base , a first scroll rib projecting from the first base , and a discharge port; a second scroll compressor body having a second base and a second scroll rib projecting from the second base , the first and second bases being axially spaced apart with the first and second scroll ribs mutually received in each other to define at least one compression chamber between an intake region and the discharge port , wherein relative movement between the first and second scroll compressor bodies is adapted to compress fluid from the intake region to the discharge port ; and a scroll tip seal projecting axially from the second scroll rib and adapted to sealingly engage the first base for sealing the at least one compression chamber ; means formed into the discharge port for accommodating sweeping movement of the scroll tip seal into a conventional discharge port region to enable scroll tip seal lengthening on the second scroll rib , characterized in that the shape of the discharge port includes an edge portion with a receding region having an inward-facing radius whose center is located outside the perimeter of the discharge port ; and that the receding region with the inward-facing radius enables the length of the scroll tip seal in the vicinity of the discharge port to be greater than it would be in the absence of the receding region with the inward-facing radius, and that the size and location of the inward-facing radius of the discharge port is determined by a seal sweep radius defined by a circular movement of an end of the scroll tip seal , so that an overlap between the scroll tip seal and the discharge port is prevented. <EOS>
