A fluid discharge apparatus including a rotation valve according to the present invention includes a fluid accommodation portion in which a first accommodation space is formed to accommodate a fluid; a piston portion in which a second accommodation space is formed to accommodate the fluid which is transferred from the fluid accommodation portion, the second accommodation space being provided with a piston which is formed to be moved in a front-back direction; a discharge unit where a nozzle is formed to discharge the fluid which is transferred from the second accommodation space by the forward movement of the piston outside; a flow path portion that includes a first flow path which extends from the fluid accommodation portion, a second flow path which extends from the piston portion, and a third flow path which extends from the discharge unit; and a rotation valve that is positioned to be rotatable between the first flow path, the second flow path, and the third flow path and selectively connects the first flow path to the second flow path or the second flow path to the third flow path in response to the rotation, in which the flow path portion may further include a fourth flow path that is adjacent to the rotation valve, a first injection port may be formed at one end of the fourth flow path to inject compressed air toward the other end of the fourth flow path, a second injection port may be formed at the other end of the fourth flow path to inject compressed air toward the one end of the fourth flow path, and an operation protrusion which is exposed to the fourth flow path and rotates the rotation valve in response to the flow of the compressed air to the fourth flow path can be formed in the rotation valve. |
