It is configured so that the injection material is discharged. When the pressing member 220 and the cylinder block 230 are connected to each other, the discharge amount increases. This will be described in detail as follows.

In the case of a general pump, a plurality of pressing members are provided in a cylinder block in which a single suction port and a single discharge port are formed. In general, a single cylinder block is provided with two or three pressing members. This is to allow the injection material to be continuously supplied by configuring the other pressing member to advance even when one of the pressing members moves backward due to the characteristics of the pressing member connected to the cam and performing reciprocating motion while repeating forward and backward. In the case of a commonly used pump, the amount of injection material injected through this cylinder block is set to about 30 liters. This is because the opening/closing member provided in the cylinder block to open and close the suction port and the discharge port is about 30 liters of injection material that can reliably open and close the flow path inside the cylinder block.If the amount of injection material is increased from 30 liters There is a limit in that the opening and closing operation of the flow path through the opening and closing member is not smooth, and the discharge amount is rather reduced.

On the other hand, in the case of the multi-injection pump according to the present invention, as described above, the pressing member 220 and the cylinder block 230 are configured to be respectively connected. That is, as shown in Fig. 4, the first opening and closing member 233 and the second opening and closing member 234 provided in each cylinder block 230 open and close the flow path inside the cylinder block so that about 30 liters of injection material is supplied. You can do it. Therefore, if the two pressing members 220 are provided, 30 liters of each can be injected from the two cylinder blocks 230, so the total injection amount is 60 liters, which is twice the discharge amount injected using a general pump.

Therefore, since at least two or more cylinder blocks 230 are individually provided in each discharge part 200, a sufficient amount of discharge can be secured.
