Scroll compressor with discharge valve

A scroll compressor comprising:

• a motor;
• an orbiting scroll member driven by said motor and having an orbiting end plate and an orbiting spiral wrap extending from said orbiting end plate, said orbiting scroll including a discharge opening;
• a non-orbiting scroll member having a non-orbiting end plate and a non-orbiting spiral wrap extending from said non-orbiting end plate in a first direction, said non-orbiting spiral wrap being intermeshed with said orbiting spiral wrap;
• a bearing housing integrally formed with and extending from said non-orbiting end plate in a second direction opposite to said first direction and toward said motor;
• and
• a drive member driven by said drive member for causing said orbiting scroll member to orbit relative to said non-orbiting scroll member whereby said spiral wraps create pockets of progressively changing volume between a suction pressure zone and a discharge pressure zone, said drive member extending through said bearing housing, said non-orbiting scroll member and said orbiting scroll member.

A scroll compressor comprising:

• an orbiting scroll member having an orbiting end plate, a hub extending from said orbiting end plate and including a discharge slot formed at a distal end thereof, and an orbiting spiral wrap extending from said orbiting end plate;
• a non-orbiting scroll member defining a discharge port communicating with said discharge slot and having a non-orbiting end plate and a non-orbiting spiral wrap extending from said non-orbiting end plate, said non-orbiting spiral wrap being intermeshed with said orbiting spiral wrap;
• a bearing housing extending from said non-orbiting end plate;
• and
• a drive member for causing said orbiting scroll member to orbit relative to said non-orbiting scroll member whereby said spiral wraps create pockets of progressively changing volume between a suction pressure zone and a discharge pressure zone.
