HORIZONTAL CANISTER

摘要

PROBLEM TO BE SOLVED: To provide a horizontal canister to perform high-efficient desorption of transpiration fuel adsorbed on an adsorbent. SOLUTION: A horizontal canister comprises a horizontally arranged case body 1; a partition plate 4 to partition the interior of the case body into two layers of one being an upper layer part 2 and the other being a lower layer part 3; a communication chamber 5 to intercommunicate upper and lower layer parts 2 and 3 on one side of the internal part of the case body; an adsorbent 9 with which the upper and lower layers 2 and 3 are filled; an atmosphere intake 6 which is formed in the other side of the internal part of the case body at the upper layer 2 and through which atmosphere air is taken in the case body; an inflow port 7 which is formed in the other side of the internal part of the case body at the lower layer 3 and through which transpiration fuel flows in; and an outflow port 8 which is formed in a position below the inflow port 7 and in the vicinity of the bottom wall of the case body and through which transpiration fuel adsorbed on the adsorbent is led out to the intake passage of an internal combustion engine.
