Antirotation reed valve systems and methods for compressors

A compressor comprising:

• a scroll compressor including a fixed scroll and an orbiting scroll, wherein the fixed scroll includes a compressor surface defining at least one valve opening, a single compressor mounting opening, and a single compressor antirotation feature;
• a reed including a reed body defining a reed mounting opening and a single reed antirotation feature, wherein the reed antirotation feature is formed on a rear boundary edge of the reed body and extends inward into the reed body from the rear boundary edge, wherein the reed is positionable between an open position where the reed does not obstruct the at least one valve opening and a closed position wherein the reed blocks at least a portion of the valve opening;
• and
• a backer including a backer body having a rear portion defining a backer mounting feature, and a backer antirotation feature extending from the rear portion, wherein the backer antirotation feature is sized and shaped to engage with the reed antirotation feature preventing rotation between the reed and the backer, wherein a width of the backer antirotation feature is narrower than a width of the rear portion, wherein the reed and the backer are mounted to the compressor by a fastener extending through the reed mounting opening, the backer mounting feature, and into the compressor mounting opening.

A method of assembly comprising:

• providing a reed including a reed body;
• forming a single reed mounting opening in the reed;
• forming a single reed antirotation slot in the reed, wherein the reed antirotation slot is formed on a rear boundary edge of the reed body and extends inward into the reed body from the rear boundary edge;
• providing a backer including a backer body having a rear portion defining a backer antirotation protrusion extending from the rear portion, wherein the antirotation protrusion is sized to engage with the reed antirotation slot and a backer mounting opening, wherein a width of the backer antirotation protrusion is narrower than a width of the rear portion;
• forming a single compressor mounting opening in a surface of a compressor;
• and
• forming a single compressor antirotation opening in the surface of the compressor, wherein the single compressor antirotation opening is sized to receive the backer antirotation protrusion.
