PROBLEM TO BE SOLVED: To provide a chemical sprinkler/mixer which injects any desired amount of a raw chemical into a sprinkling liquid flowing through the pressure feeding passage of the sprinkling liquid in proportion to the flow rate of the sprinkling liquid in a chemical sprinkling system. SOLUTION: A reciprocating or rotary fluid motor 1 rotated by a liquid pressure-fed from a pressure pump is arranged in series piping to the pressure feeding passage of the sprinkling liquid. The sprinkling liquid fed from the pressure pump to an injection port 2 of the sprinkling liquid is fed from a sprinkling liquid discharge port 3 to a sprinkling nozzle. A cam 4 is mounted on the rotating shaft 8 of the fluid motor 1. A compression pump 17 consisting of a raw liquid suction port 6 provided with a compression cylinder 5, a compression piston 10 and a check valve 41, and of a raw liquid discharge port 7 is constituted so as to drive the cam 4. The raw liquid suction port 6 is piped to a raw liquid tank, and the raw liquid discharge port 7 is piped to the sprinkling liquid feeding passage. Thereby the discharge rate per stroke of the compression piston 10 is controlled by the depth of the compression pump 17 mounted and fixed into a compression pump mounting part 42.
