Fig. 1 illustrates a conventional progressive dispenser in the prior art, which includes a dispenser valve body 11, the dispenser valve body 11 is provided with an inlet 12 on the front side as shown in fig. 1, a plurality of outlets 13 on the left side as shown in fig. 1, a plurality of plunger cavities penetrating through the left and right sides are arranged inside the dispenser valve body 11, the plunger cavities are communicated with a lubricating medium channel inside the dispenser valve body 11 and further communicated with the inlet 12 and the outlets, and a plurality of plungers 14 are arranged in the plunger cavities, and the outlets are communicated or sealed by adjusting the positions of the plungers 14 in the plunger cavities. The plunger 14 is controlled by an electronic control assembly composed of electronic components such as a program controller, a motor, a switch, a signaling element, and the like, wherein reference numeral 15 in fig. 1 is the signaling element in the electronic control assembly. During operation, after the lubricating medium enters from the inlet, the plunger inside the distributor moves, so that the lubricating medium is discharged from the outlet according to the distribution requirement.

The progressive distributor is designed according to the theoretical calculation value of the oil consumption of the lubricating point to select the model of the distributor at the beginning of the design. The selection of the type of the distributor is mainly to confirm the displacement of each outlet of the distributor, and after the type of the distributor is determined, the displacement of each outlet of the distributor is correspondingly determined. The displacement of the dispenser is determined by the diameter and stroke of the plunger, while the stroke of each plunger of a progressive dispenser is often the same, and the direct factor affecting the displacement of the dispenser is the diameter of the plunger. The sizes of plunger cavities on corresponding dispenser shells of plungers with different displacements of the conventional progressive dispenser are different, so that different plungers cannot be mutually replaced. However, in the actual use process, the actual demand of the lubricating point often deviates from the theoretical calculated value to some extent, the displacement of the distributor needs to be adjusted according to the actual situation, and the whole distributor or the oil feeding block can only be replaced at this time. However, the cost of replacing the dispenser and the oil block is very high, which greatly increases the maintenance cost for the user; furthermore, the replacement of the oil cake or the entire distributor requires the disassembly of the inlet-outlet connection lines to the original distributor, which also increases the maintenance effort.

In view of the above-mentioned circumstances, there is a need to develop a structure capable of satisfying the requirements for adjusting different discharge capacities without replacing the entire distributor or oil feeding block.
