, Piston pump works: MCY14-1B quantitative axial piston pump, as shown in Figure 1, the principle is relatively simple, the pump drive shaft and the cylinder the spline, led cylinder rotation, uniform enacted in the cylinder on the seven plunger around the center of rotation of the drive shaft. Each plunger end have a slipper centering spring steel ball through the inner sleeve, return plate slipper pressure on the axis tilt angle of the swash plate. When the cylinder is rotated, the plunger simultaneously reciprocate, the completion of the operation of the suction and pressure oil. Centering spring jacket cylinder pressure on the oil pan from the initial sealing role. Slipper with oil hydraulic static equilibrium, not only to reduce the wear of the pump, and the pump has high volumetric efficiency and mechanical efficiency.
