Abstract
An oil catching device and an oil pump for an internal-combustion engine are provided, having an oil catching housing which is arranged below a crankcase and which has at least two oil collecting spaces, in a first oil collecting space an oil pump being arranged which has two pump stages, at whose two suction stages one oil suction pipe, respectively, is connected. The first oil suction pipe reaches in the first oil collecting space in order to deliver the lubricating oil by way of the delivery side of the first pump stage to the consuming devices, and the second oil suction pipe connected with the second suction stage leads to a second oil collecting space. On its top side, the housing of the oil pump has an opening connected with the delivery side of the second pump stage, by way of which opening, the oil suctioned out of the second oil collecting space is delivered into the first oil collecting space. This achieves a defoaming of the suctioned-off lubricating oil.
