The present embodiment shows a distributor with only three valve core assemblies 31 combined, i.e. a start valve core, an end valve core and a middle valve core, but does not prevent the present application from embodiments with other numbers of middle valve cores.

As shown in fig. 4-5, the working principle of the dispenser is shown, which is as follows:

the lubricant enters from the oil inlet 21 at the upper part, reaches the left ends of the valve cores II and III after passing through the annular groove and pushes the valve cores II and III to move rightwards, so that the lubricant in the valve core cavity is discharged from the oil outlets E1 and E2 in sequence. When the valve core III reaches the extreme position of the right end, the lubricant entering the distributor 1 reaches the right end of the valve core I through the annular groove on the left side, and the valve core I is pushed to move leftwards, so that the lubricant in the valve core cavity is discharged from the oil outlet E3; similarly, when the three valve core movement directions are opposite to the above process, the corresponding lubricants are discharged from the oil outlets E4, E5 and E6 in sequence.

Wherein, as long as the emollient that gets into distributor 1 maintains certain pressure, the inside oil outlet merging mechanism that sets up of distributor 1 just can be according to customer's demand, and the suitable flow is directly and go out in inside, greatly improves distributor 1's practicality.
