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