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.
Claims10
A rotary piston pump, in particular claw pump, comprising:
- a housing which has a housing inlet on a housing upper side, wherein the housing inlet is connected to a gas channel that is integrated into the housing and extends transversely to a rotational axis (x) of a piston,
- a filter part arranged in a filter receptacle, wherein the gas channel creates a flow connection to a gas outlet of the filter part,
- wherein in an installed state, the filter part is accessible from a side perpendicular to the upper side of the housing, such as for maintenance purposes, wherein a modular design is provided, which allows the integrated filter part to clean the gas before the gas flows into a pump chamber, wherein the filter receptacle is connected to a gas inlet which is formed separately from the housing inlet, and allows a combination of the housing inlet, which is exposed after removal of a lid part, with a suction attachment so that the housing inlet directly forms the gas inlet.
