Abstract
A system is herein disclosed for use in the delivery of fluid from a reservoir to a relatively reciprocating fluid discharge mechanism via an arrangement of coiled tubes which may be expanded or retracted with reciprocation of the discharge mechanism. The system is preferably arranged with a series of concentrically coiled tubes, each tube carrying a different fluid to the discharge mechanism. Adjacent coils are wrapped in opposing rotational directions so as to create a web-like matrix which supports the coils in their extended form.
