SUCTION PIPE

Document Type and Number:

WIPO Patent Application WO/1986/007529

Kind Code:

A1

Abstract:

Two-stage telescopic suction pipe formed by inserting a smaller-diameter pipe made of a synthetic resin into a larger-diameter pipe made of a synthetic resin. In order to prevent a fluid from leaking at the joint portion of the larger-diameter pipe and smaller-diameter pipe, and the smaller-diameter pipe from swinging when the suction pipe is used in an extended state, the smaller-diameter pipe is provided with a flange which contacts with the inner surface of the larger-diameter pipe, and the larger-diameter pipe with a projection, which supports the smaller-diameter pipe, on the inner surface thereof. The composition of the material of which the larger-diameter pipe is made and that of the material of which the smaller-diameter pipe member is made are different from each other.
