Abstract:
A scroll compressor comprising:a first scroll member having a base and a generally spiral wrap extending from said base; a second scroll member having a base and a generally spiral wrap extending from said base; a shaft driven by a motor, said shaft causing said second scroll member to orbit relative to said first scroll member; a housing including a center shell surrounding said motor and said first and second scroll members; an end cap attached to said center shell at an end adjacent said first and second scroll members; a separator plate mounted between said end cap and said first scroll member; a suction tube for providing suction pressure gas into an interior chamber receiving said motor, and leading to a passage such that suction pressure gas can enter compression chambers defined between said spiral wraps of said first and second scroll members, a discharge outlet extending from said compression chambers through said first scroll member, and through a discharge tube into a discharge plenum, said separator plate separating said housing into said discharge plenum and said interior chamber, and preventing gas from moving from said discharge plenum into said interior chamber, and said separator plate being interference fit into said end cap; and a pressure release valve also being interference fit into said separator plate and providing communication between said discharge plenum and said interior chamber when a gas pressure in said discharge plenum exceeds a predetermined maximum.
