Claim:
Oil catching system for an internal-combustion engine, particularly for an opposed-cylinder engine, having an oil catching housing arranged below a crankcase, in which oil catching housing an oil suction space is provided from which lubricating oil is transported to consuming devices by way of a main oil pump equipped with an oil suction pipe to consuming devices, wherein at least one oil collecting space adjoins the oil suction space, in which oil collecting space the lubricating oil coming from the consuming devices is returned by way of an oil pipe, the oil suction space being separated from the oil collecting space by at least one oil separating wall in which at least one passage opening is arranged which can be controlled by way of a flap, by way of which passage opening the lubricating oil can flow from the oil collecting space into the oil suction space, and wherein a wall section is provided which bounds the oil collecting space and is spaced away from the oil separating wall, which wall section, relative to the passage opening in the oil separating wall, extends in a diagonally inclined manner and is used as a flow-off surface for the lubricating oil returned into the oil collecting space, and two oil return flow pipes are arranged in the oil collecting space, which oil return flow pipes are connected on one side with oil return flow ducts integrated in the crankcase and, on the other side, in each case, lead into at least one opening provided in the oil separating wall.
