Fixed displacement axial piston motors are plug-in fixed motors with an bent axis design, equipped with axial conical piston rotary bodies for hydrostatic drives in open and closed circuits. In axial piston units with a bent-axis design, the pistons, converting hydraulic pressure into torque, are arranged diagonally to the shaft and located directly above it. In an open circuit, the hydraulic fluid flows from the reservoir to the hydraulic pump, where it is fed to the hydraulic motor through the directional valve. In a closed circuit, hydraulic fluid flows from the hydraulic motor directly back to the axial piston pump. Reversing the flow of hydraulic fluid in the pump changes the rotational output of the hydraulic motor.
