Structure and operation explanation

• This pump has a structure with 2 pumps positioned on the same shaft coupled with the 1st gear (116) and rotation force is distributed to different shafts by the gear structure. The 2 pumps are driven by transmitting the rotation of the power source to the front side drive shaft (111). Auxiliary pumps installed on different shafts can also be driven at the same time.
• The pump can be roughly divided into the rotary group, which is the main part of the pump rotating, the swash plate group, which changes the discharge flow, the valve block group, which switches between oil suction and discharge, and the PTO group that transmits the gear pump drive shaft.
• The rotary group is made up of drive shafts (111 and 113), cylinder block (141), piston shoes (151and 152), holder plate (153), sphere bushing (156), bearing spacer (127), and cylinder spring (157). The drive shaft is supported at both ends with bearings (123 and 124). The shoe is caulked to the piston and forms the spherical joint, reduces the thrust force generated by the load pressure, and has a pocket section for balancing the pressure for sliding lightly on the shoe plate (211). The piston shoe sub-group is pressed against the shoe plate by the cylinder spring via the holder plate and spherical bushing so that it can slide smoothly on the shoe plate. Also, in the same way, the cylinder block is pressed against the valve plates (313 and 314) by the cylinder spring.
• The swash plate group comprises the swash plate (212), shoe plate, swash plate support board (251), tilting bushing (214), tilting pin (531), and servo piston (532). The swash plate is supported by the swash plate support board at the cylindrically shaped section formed by the opposite side of the shoe sliding surface. By leading the hydraulic pressure force controlled by the regulator into the hydraulic pressure chambers on both sides of the servo piston, the servo piston moves left and right. This moves the swash plate back and forth on the swash plate support board via the tilting pin spherical section and changes the tilting angle (α).
• The valve block group comprises the valve block (312), valve plates (313 and 314), and spring pin (886). The valve plate, which has two hook-shaped ports, is installed on the valve block. Its function is to feed oil to the cylinder block and recover it from the cylinder block. The oil switched by the valve plate is connected through the valve block to the outside pipes.
• The PTO group comprises the 1st gear, 2nd gear (117), and 3rd gear (118). The 2nd and 3rd gear are supported by their respective bearings (125 and 126) and can install the valve block.
• Now when the drive shaft is driven by the power source (motor, engine, etc.), the cylinder block is also rotated at the same time via the spline coupling. When the swash plate tilts, the piston located at the center of the cylinder block moves reciprocally relative to the cylinder while turning with the cylinder block. Therefore, if looking at one piston while the cylinder block turns one rotation, the piston moves away from the valve plate (oil intake stroke) for 180 ° of the cylinder block rotation, then moves toward the valve plate (oil discharge stroke) for the remaining 180°. When the swash plate tilting angle (α) is 0, the piston subassemblies (151 and 152) do not move through a stroke and oil is not discharged.
• Also, at the same time, the drive shaft rotation is taken out by the 1st gear and transmitted
  through the 2nd gear to the 3rd gear to drive the pilot gear pump coupled with the 3rd gear.
