PURPOSE: To provide a fluid delivery system capable of delivering a fluid to a discharge mechanism performing reciprocating motion from a stationary reservoir without exerting improper stress or fatigue on a tube. CONSTITUTION: In a fluid delivery system 20 used in order to deliver a fluid to a fluid discharge mechanism 14 performing relative reciprocating motion from a reservoir 12 through a coiled tube system 20, the tube system 20 can extend and retreat along with the reciprocating motion of the discharge mechanism 14. This system 20 is pref. constituted by using a series of concentric coiled tubes and these tubes carry different fluids to the discharge mechanism 14. Adjacent coils 22a, 22b, 22c, 22d are wound in mutually opposite rotary directions so as to form a web-like matrix supporting the coils 22a, 22b, 22c, 22d at a time of the extension of the system 20. |
