1. When the swash plate structure starts, the friction between the piston shoe and the swash plate is large (the static pressure support has not been established yet), so the swash plate type starting torque is low, and the inclined axis is preferred when the starting is frequent.
2. The swash plate type has a high-speed relative movement between the piston shoes and the swash plate relative to the oblique-axis piston pump type, so the swash plate type has high requirements for oil cleanliness.
3. The swash plate has a small moment of inertia relative to the oblique axis variable, and its variable response time is fast. Therefore, it is advantageous for the pump.
4. The swash plate structure to make a pump has an advantage of being a through-drive pump.
