  • Motor-hydraulic machine unit for attachment to a hydraulic assembly
    Patent number: 11795926
    Abstract: A motor-hydraulic machine unit includes an electric motor, a hydraulic machine, and a connection body that has a planar connection surface which delimits first and second working connections. The first and second working connections are each in fluid exchange connection with the hydraulic machine via an assigned first fluid duct in the connection body. The electric motor and the hydraulic machine have a common axis of rotation which is arranged substantially parallel to the connection surface. The hydraulic machine and the electric motor are arranged on opposite sides of the connection body in the direction of the axis of rotation. The connection body is traversed by a drive aperture in the direction of the axis of rotation. The electric motor and the hydraulic machine are in rotary drive connection in a region of the drive aperture.
