Compressor having seal assembly

A compressor comprising:

• a shell defining a first pressure region and a second pressure region;
• a muffler plate separating the first pressure region and the second pressure region;
• a first scroll member disposed within the shell and including a first end plate and a first scroll wrap, the first end plate defining an annular recess and a discharge recess, the discharge recess in communication with the first pressure region;
• a second scroll member including a second end plate and a second scroll wrap, the second scroll wrap meshingly engaging the first scroll wrap to define a compression chamber therebetween;
• a first sealing member at least partially disposed in the discharge recess and fluidly separating the first and second pressure regions from each other;
• and
• a second sealing member at least partially disposed in the annular recess and spaced apart from the muffler plate, the second sealing member forming a third pressure region that is fluidly isolated from the first and second pressure regions;
• a spacer at least partially disposed within the annular recess and including a first surface contacting the second sealing member and a second surface configured to contact the muffler plate, wherein the spacer includes radially extending grooves that allow working fluid to flow between the muffler plate and the spacer when the second surface of the spacer is in contact with the muffler plate;
• a discharge valve assembly disposed within the discharge recess of the first scroll member;
• and
• a biasing member disposed within the discharge recess, wherein the biasing member is compressed between the discharge valve assembly and the first sealing member,
• wherein the muffler plate includes a flange at least partially extending into the discharge recess and partially defining a discharge opening that provides discharge gas from the discharge recess to the first pressure region,
• wherein the first sealing member includes a first portion and a second portion that cooperate to define an L-shaped cross section, wherein the first portion extends radially inward from the second portion and sealingly contacts an axial end surface of the flange of the muffler plate, and wherein the second portion extends axially downward from the first portion and sealingly contacts an inner diametrical surface of the discharge recess,
• wherein the second sealing member has a U-shaped cross section.

• wherein the first sealing member includes an end portion that at least partially extends into the discharge opening of the muffler plate, and wherein the first sealing member is moveable downwardly when the compressor is in a shutdown state to allow discharge gas in the first pressure region to flow toward the second pressure region.
