A compressor comprising: a housing; a non-orbiting scroll member supported within said housing and including a first end plate and a first spiral wrap extending from said first end plate; and an orbiting scroll member supported within said housing and including a second end plate having a second spiral wrap extending therefrom and meshingly engaged with said first spiral wrap to form a series of compression pockets, characterized by: a first porting (148, 148') extending through said first end plate and having an angular extent of at least twenty degrees; and said first porting being in communication with a first of said compression pockets during a portion of a compression cycle of said orbiting and non-orbiting scroll members, said first and second spiral wraps abutting one another to define first modulated capacity pockets when said orbiting scroll member is in a first position, said first modulated capacity pockets including a set of radially outermost compression pockets located radially inward relative to said first porting and isolated from communication with said first porting during an entirety of said compression cycle, said first porting aligned with said second spiral wrap at a location radially outward from and directly adjacent said first modulated capacity pockets when said orbiting scroll member is in the first position, wherein said first porting is in selective communication with a bypass location external to said one of said compression pockets to provide a reduced capacity operating mode for the compressor. a housing; a non-orbiting scroll member supported within said housing and including a first end plate and a first spiral wrap extending from said first end plate; and an orbiting scroll member supported within said housing and including a second end plate having a second spiral wrap extending therefrom and meshingly engaged with said first spiral wrap to form a series of compression pockets, characterized by: a first porting (148, 148') extending through said first end plate and having an angular extent of at least twenty degrees; and said first porting being in communication with a first of said compression pockets during a portion of a compression cycle of said orbiting and non-orbiting scroll members, said first and second spiral wraps abutting one another to define first modulated capacity pockets when said orbiting scroll member is in a first position, said first modulated capacity pockets including a set of radially outermost compression pockets located radially inward relative to said first porting and isolated from communication with said first porting during an entirety of said compression cycle, said first porting aligned with said second spiral wrap at a location radially outward from and directly adjacent said first modulated capacity pockets when said orbiting scroll member is in the first position, wherein said first porting is in selective communication with a bypass location external to said one of said compression pockets to provide a reduced capacity operating mode for the compressor. a first porting (148, 148') extending through said first end plate and having an angular extent of at least twenty degrees; and said first porting being in communication with a first of said compression pockets during a portion of a compression cycle of said orbiting and non-orbiting scroll members, said first and second spiral wraps abutting one another to define first modulated capacity pockets when said orbiting scroll member is in a first position, said first modulated capacity pockets including a set of radially outermost compression pockets located radially inward relative to said first porting and isolated from communication with said first porting during an entirety of said compression cycle, said first porting aligned with said second spiral wrap at a location radially outward from and directly adjacent said first modulated capacity pockets when said orbiting scroll member is in the first position, wherein said first porting is in selective communication with a bypass location external to said one of said compression pockets to provide a reduced capacity operating mode for the compressor.
