Removal of oils and liquids, esp. from engine casings

摘要

The oils and liquids are sucked out into a container (1) by a suction unit (4) and pump (3). The suction pressure can be from 5 to 40 mbar. The fluids can then be drained off into a collection container (2), which may arranged underneath. The suction unit may also be fitted with multiple adaptors. Combination of the container, collection container, pump and suction unit into a single device, and the fitting of a long hose onto the suction unit, are also discussed.
