The extractor has a Venturi air discharge outlet (E) for compressed air to form the vacuum in the transfer tank (G). The extractor can have a safety system with a level valve (T,U,V,Y) which prevents the aspiration into the tank when a maximum level is attained. The extractor can have a compressed air scavenging feed (M) which evacuates the oil contained in the tank towards a storage container. The extractor can have two three-way valves to control flow between the crankcase, tank and compressed air feed.
