Fluid collection system

Abstract From the Canadian patent

A collection system having a vacuum source in flow communication with a closed fluid collection vessel which is in flow communication with an inlet conduit disposed to apply the vacuum to non-gaseous fluids. The non-gaseous fluids to be collected are ingested through the inlet conduit through an inlet port to the closed collection vessel where they are retained. The collection vessel is kept at a negative gauge pressure through an outlet port connecting the collection vessel to the vacuum source. A fixed restriction is provided at one point in the vacuum line to conserve energy by reducing the flow of gas through the system to the vacuum source.
