Abstract
A fluid jetting apparatus includes a nozzle part, a driving part, and a membrane. The nozzle part has an ink chamber and a nozzle hole. The driving part has a working fluid chamber and a heating element. The membrane serves as a partition between the ink chamber and the working fluid chamber. The working fluid chamber has an ink feeding hole through which the ink is fed from an external ink source. An intercommunicating hole is formed on the ink chamber, intercommunicated with the working fluid chamber. The ink is fed into the working fluid chamber and is fed to the ink chamber through an intercommunicating passage. During the heating operation of the heating element, the ink chamber is pressured by the membrane, so that the ink is jetted through the nozzle hole. The ink in the working fluid chamber flows into the ink chamber through the intercommunicating passage, and the ink flows into the working fluid chamber through the ink feeding hole. Accordingly, the working fluid chamber is cooled, and the durability of the fluid jetting apparatus is lengthened.
