The conduit within the reservoir conducts the refrigerant flow from the inlet to a region of the reservoir above the outlet.

Why it's free to use
- Filed April 2, 1992 and granted May 12, 1998. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 2, 2012.
