Oil tank for dry sump engines

摘要

An oil tank 10 for a dry sump engine has a housing 11 having an upper region 13 and a lower region 14 in which the oil is contained. The lower region 14 has an oil outlet 19 to feed a pump which supplies oil to the engine. The upper region 13 houses a swirl tube 16 connected to an oil inlet 17 for air to separate from the incoming oil. The upper region 13 includes an air outlet 15 and is provided with two dished baffle plates 30, 31 each shaped to form a collector area which slopes towards the swirl tube 16 in order to reduce droplets of condensation formed in the upper region flowing into the lower region 14. The wall of the swirl tube 16 is heated by the incoming oil to promote vaporisation of droplets of condensation collected in the collector area.
