Scroll machine having discharge port inserts

A scroll machine comprising:

• a first scroll member having a spiral wrap projecting outwardly from an end plate, said first scroll member defining a first center hole;
• a second scroll member having a spiral wrap projecting outwardly from an end plate, said scroll members being mounted for relative orbital movement therebetween with said wraps intermeshed with one another to define an outer port;
• a first plug disposed within said first center hole, said first plug including a first discharge port, said first discharge port being non-concentric with said first center hole;
• a drive member for causing said scroll members to orbit with respect to one another such that said wraps create pockets of progressively changing volume traveling between said ports whereby fluid received in one of said pockets through one of said ports is discharged through the other of said ports.

A scroll machine comprising:

• a first scroll member having a spiral wrap projecting outwardly from an end plate, said first scroll member defining a first discharge port;
• a second scroll member having a spiral wrap projecting outwardly from an end plate, said scroll members being mounted for relative orbital movement therebetween with said wraps intermeshed with one another to define an outer port;
• a first insert disposed within said first discharge port, said first insert shifting the effective center line of said first discharge port;
• a drive member for causing said scroll members to orbit with respect to one another such that said wraps create pockets of progressively changing volume traveling between said ports whereby fluid received in one of said pockets through one of said ports is discharged through the other of said ports, said spiral wrap of said second scroll member engaging said first insert to define the performance of said scroll machine.

A scroll machine comprising:

• a first scroll member having a spiral wrap projecting outwardly from an end plate, said first scroll member defining a first discharge hole;
• a first insertable member disposed within said first discharge hole for modifying the shape of said first discharge hole, said first insertable member comprising a first insert secured within said first discharge port, said first insert including a first insert discharge port, said first insert discharge port being in non-concentric relationship to said first discharge hole when said first insert is secured within said first discharge hole;
• a second scroll member having a spiral wrap projecting outwardly from an end plate, said scroll members being mounted for relative orbital movement there between with said wraps intermeshed with one another to define an outer port;
• a drive member for causing said scroll members to orbit with respect to one another such that said wraps create pockets of progressively changing volume traveling between said ports where by fluid received in one of said pockets through one of said ports is discharged through the other of said ports, said spiral wrap of said second scroll member engaging said first insertable member to define the performance of said scroll machine.

A method of manufacturing a scroll machine to meet a specified performance requirement, said method comprising the steps of:

• producing a first scroll member having a spiral wrap and a center port;
• producing a plurality of inserts, each of said inserts being positionable within said center port, each insert being capable of adapting said center port to meet a different performance requirement for said scroll machine;
• selecting one of said plurality of inserts for meeting said specified performance requirement;
• securing said insert within said first center port;
• assembling said first scroll member with a second scroll member having a spiral wrap;
• and
• assembling one of said first and second scroll members with a drive member.

• producing a second scroll member having a spiral wrap and a second center port;
• producing a first and second plurality of inserts, each of said first plurality of inserts being positionable within said first center port, each of said second plurality of inserts being positionable within said second center port, each set of said first and second inserts being capable of adapting said first and second center ports, respectively, to meet a different performance requirement for said scroll machine;
• selecting one of said first and second plurality of inserts for meeting said specified performance requirement;
• securing said first insert in said first center port;
• securing said second insert in said second center port;
• and
• assembling said first and second scroll members with a drive member.
