  • Patent number: 4271725
    Abstract: A hydraulic motor unit is provided wherein a bent axis type axial piston motor having a high operating efficiency is incorporated while the compactness of the unit is maintained. The dimensional features of this invention are attained, in one aspect, from a special arrangement in which a multiple-plate type hydraulically actuated brake unit is disposed in an intermediate position between bearings supporting an output shaft of the hydraulic motor. Another aspect of such dimensional features of this invention resides in the arrangement such that the control valve unit, which can otherwise be a substantial obstacle in the installation work, is located neatly in a space made available by the specific construction peculiar to the bent axis type hydraulic motor unit so that the control valve unit may never become an obstacle in either installed on or removed from a machine or vehicle.
