Abstract
A hydraulic system having a standpipe in a sump with ports on the side of the standpipe and one smaller port on the top of the standpipe. The majority of the oil flows into the standpipe through the side ports thereby reducing the downward suction and flow at the top of the standpipe to eliminate the formation of a vortex at the top of the standpipe. As a result, less air is drawn into the oil producing a more consistent oil/air mixture and more consistent sump oil level.
