Variable displacement axial-piston pumps in swashplate design are used for hy-draulic actuators combined of pump and motor, operating in closed circuit systems. They are used for driving mobile machines like combines or rotating technological equipment like transit mixer drums etc.Axial-piston pumps are easily controlled and relatively compact. Pump flow is directly proportional to the cylinder block speed and displacement varied with the swashplate positioning.Flow direction is reversed with a tilt of the swashplate in either of the opposite directions from its neutral position.Modular control valve adjusting provides flexibility of control combinations.MH - hydromechanical proportional control system. Due to the control system the swashplate is held in the required position, thus maintaining amount of the flow at the preset level.ER - electrohydraulic 3 positioned control system. Used for drive operating to the system turn on-turn off-turn on. Can be supplied with maximum displacement control.?????????-????????? ???????????? ?????? ? ????????? ??????S ?????series Variable displacement axial-piston pumps in swashplate design5?????????-????????? ???????????? ?????? ? ????????? ??????
