Abstract
A filter for cleaning lubricating oil of an internal combustion engine has a filter housing with an access opening on an upper side to insert and remove filter elements. A cover is arranged to close the access opening. The housing has an inlet opening for dirty fluid and an outlet opening for clean fluid. Furthermore, a drain opening is provided in the housing which can be opened and closed with a closure element. The closure element is operationally coupled to the cover such that when the cover is closed, the closure element closes the drain opening, and when the cover is opened, the closure element opens the drain opening, allowing the fluid to drain out of the housing.
