Claims

[Scope of utility model registration request]

It has a plunger insertion hole that penetrates into which two plungers are inserted, and has two ports that communicate with the plunger insertion hole, and at one port position, the gap between the two plungers is widened and suction is carried out, and this gap is increased. This is a barrel used in a two-plunger type pump that moves both plungers to the other port position while holding them, and then brings both plungers close together to discharge. A barrel of a two-plunger type pump, characterized in that a seal insertion recess is formed around a plunger insertion hole.
