<P>PROBLEM TO BE SOLVED: To suppress temperature rise of injected liquid, as well as simplify maintenance and extend life time of an apparatus. <P>SOLUTION: In a machine for injecting liquid, at least one air pump is used, wherein the air pump is connected to communicate with at least one injection head 140 having holes for nozzles. High-pressure injected liquid flows from the air pump into the injection head 140, preferably through a filter mounted in the injection head without using screws. To further minimize contamination, the liquid entering into the injection head will not contact to any screw present in the head and the nozzles. An air pressure regulator is mounted to ensure that a steady flow of the injected liquid is delivered to an injection object via each injection head in a desired pressure. The air pressure regulator also serves to eliminate fluctuation in delivery of the liquid by the air pump. Cleaning of the machine is simplified by moving sensitive components into a sealed enclosure to remove them from a wet working environment. <P>COPYRIGHT: (C)2010,JPO&INPIT |
