2160128 weichai oil pump working principle：
Oil suction process: the plunger is driven by the cam of the camshaft. When the convex part of the cam leaves the plunger, the plunger moves down under the action of the plunger spring, the volume of the oil chamber increases, and the pressure decreases; when the plunger sleeve is on When the radial oil inlet hole is exposed, the fuel in the low pressure oil cavity flows into the pump cavity along the oil inlet hole.
Oil pumping process: When the convex part of the cam pushes up the plunger, the volume in the pump cavity decreases and the pressure increases. The fuel flows back to the low pressure oil cavity along the radial oil hole on the plunger sleeve; When the radial oil hole on the plunger sleeve is completely blocked, the pressure on the pump chamber increases rapidly; when this pressure overcomes the pretension force of the outlet valve spring, the outlet valve moves upward; when the outlet valve is up When the decompression ring belt leaves the valve seat, the high-pressure diesel is pumped into the high-pressure fuel pipe and injected into the Cylinder through the fuel injector.
Oil return process: As the plunger continues to move upward, when the chute on the plunger communicates with the radial oil hole on the plunger sleeve, the fuel in the pump cavity passes through the axial oil passage on the plunger, obliquely The oil passage and the oil hole on the plunger sleeve flow back to the low-pressure oil chamber, and the pump oil stops.
