Abstract

The air cooler for hydraulic oil pumps is a so-called "cooling pump carrier", that is the cooler is incorporated into the pump carrier for flange-mounting the pump on the drive motor. The cooler has a radial fan (10) mounted on the drive shaft (11) with axial intake chamber and a cooling element arranged concentrically around this chamber. This cooling element is divided into a plurality of, preferably two, separate cooling elements (5, 5a), to which a corresponding number of separate pressure chambers (1, 1a) lead, the intake openings on the circumference leading to the intake chamber being offset in relation to the cooling elements. Two cooling elements (5, 5a) and a corresponding number of intake openings are advantageously provided which on the circumference each lie opposite one another on a diameter, these diameters being perpendicular to one another. This results in an especially advantageous embodiment by means of which any mixing of entering and emerging cooling air is avoided. In addition standard "straight" cooling elements can be used. <IMAGE>
