Abstract
A pump housing, including a pump unit having a collection chamber that receives leaking brake fluid. In the installed position of the pump unit, an outflow bore leads downward from the collection chamber to the ambient air. A body which in one direction allows the outflow of leaking brake fluid and in another direction prevents the entry of splashing water and standing water is press-fitted into the outflow bore. The body comprises a porous sintered metal and on the ambient air side has a flat face end, while its face end toward the collection chamber is embodied in raised fashion.
