An aspiration-type spray system includes a spraying mechanism, a gas cylinder, and a chamber for containing fluid to be sprayed. The spraying mechanism aspirates and sprays the fluid contained in the chamber by spouting a gas from the gas cylinder. The spraying mechanism includes a cylinder-connecting member connected to the stem of the gas cylinder, a fluid-connecting member connected to the fluid chamber, and an actuator for hand-operated spraying. An open/close valve is provided in the fluid-connecting member, and the operation of the actuator not only opens the open/close valve of the fluid-connecting member but presses the stem.
