Samsung patents compressor mixing scroll and rotary stages
Samsung describes a compressor that squeezes refrigerant gas in two steps inside a single housing. The gas first passes through a scroll mechanism, which uses two spiral-shaped parts to compress it, and then moves into a rotary section where a roller spins against a cylinder wall for final compression.
In the filing’s own words
A compressor including a case including an inlet port, and an outlet port; a scroll compressing portion including a fixed scroll inside the case, and an orbiting scroll configured to orbit with respect to the fixed scroll; and a rotary compressing portion including a cylinder inside the case, and a roller configured to rotate along an inner wall of the cylinder inside the cylinder, wherein the case, the scroll compressing portion, and the rotary compressing portion are configured such that a refrigerant flowing into the case through the inlet port passes through the scroll compressing portion, then passes through the rotary compressing portion, and is then discharged to an outside of the case through the outlet port.
What exactly they claim (claim 1)
1. A compressor comprising: a case including: an inlet port, and an outlet port; a scroll compressing portion including: a fixed scroll inside the case, and an orbiting scroll configured to orbit with respect to the fixed scroll; and a rotary compressing portion including: a cylinder inside the case, and a roller configured to rotate along an inner wall of the cylinder inside the cylinder, wherein the case, the scroll compressing portion, and the rotary compressing portion are configured such that: a refrigerant flowing into the case through the inlet port passes through the scroll compressing portion, then passes through the rotary compressing portion, and is then discharged to an outside of the case through the outlet port.
