Abstract
A snap-on device for butt connecting in fluidtight manner one or more pairs of pipes, in particular vehicle fuel supply pipes. The device consists of a cup-shaped body having at least a first integral pipe connected hydraulically to a seat inside the body; and a block connectable inside the seat and molded on at least a second pipe, so that the end of the second pipe projects frontwards of the block in the insertion direction of the block inside the seat. The seat presents a recess coaxial with the first pipe and designed to receive the projecting end of the second pipe in sliding and fluidtight manner; and releasable locking structure for locking the block inside the seat, while at the same time permitting axial movement of the block and the projecting end of the second pipe inside the seat and recess respectively.
Claims16
An assembly for connecting together at least one pair of fluid conduits, comprising:
- a body having a first fluid conduit fixedly connected to one end thereof, a hollow seat portion defined within a second opposite end thereof, and a recess portion interposed between and fluidically connecting said seat portion to said first fluid conduit;
- a block member having a second fluid conduit fixedly mounted therein such that one end of said second fluid conduit extends outwardly from said block member, in the direction of insertion of said block member within said seat portion of said body, such that said one end of said second fluid conduit can fluidically communicate with said first fluid conduit and yet be slidably disposed within said recess portion of said body so as to provide for thermal expansion of said one end of said second fluid conduit within said recess portion of said body;
- releasable locking means defined between said block member and said body for releasably locking said block member within said seat portion of said body at such a position that axial movement of said block member within said seat portion of said body, and axial movement of said one end of said second fluid conduit within said recess portion of said body, is able to be achieved after said block member has been locked within said body so as tp permit said thermal expansion of both said block member and said second fluid conduit member of said assembly within said seat portion and said recess portion, respectively, of said body;
- rib means defined upon said block member;
- and
- groove means defined upon said body and extending axially throughout said seat portion of said body for accommodating said rib means of said block member so as to permit said axial movement of said block member within said seat portion of said body after said block member has been releasably locked within said seat portion of said body.
