Abstract
In a bypass filter unit, in particular, for filtering supplies of hydraulic oil in a bypass flow, comprising a motor-driven pump and a fixedly mounted filter housing closeable by a cover and containing an exchangeable filter element, it is proposed that the drive of the pump, the pump and the filter housing be arranged coaxially with one another, with the end of the filter housing that is closeable by the cover pointing upwards, that the filter housing be directly connected to the pump, and that the filter housing form a receptacle for the clean oil while the filter element is being changed, so as to enable changing of the filter element and renewal of the filter in a simple way and without risk of soiling the clean oil side.
