<p>The engine (1) has a scoop (8) connected to a connecting rod (3) and extended in direction of a case (6) containing oil. The case has walls (11a, 11b) at interior of its volume and on sides of an orbit plane (10) of the scoop. The walls form an obstacle to movement of the oil from the case. Each wall is transversely extended with respect to a horizontal rotational axis (5) of a crankshaft (4) and raised from a lower part of the case to top of a distal end (9) of the scoop when the case is in a lower position. An upper edge of one wall is closer to the plane than a lower edge of the wall.</p> |
