Abstract

A rotary piston pump, in particular a claw pump, includes a housing which, when placed in a customary manner, has a housing inlet in a housing upper side. In order to further improve a rotary piston pump in a beneficial way, the housing inlet is connected to a gas channel that is integrated in the housing and extends transversely to a rotational axis of the piston, which gas channel creates a flow connection to a gas outlet of a filter part arranged in a filter receptacle. In the installed state, the filter part is accessible from a side perpendicular to the housing upper side, for maintenance purposes, for example.
