Abstract: A canister that adsorbs and desorbs an evaporated fuel generated in a fuel tank of a vehicle includes an outer case, an inner case, a connecting port, and a sealing member. The inner case has a cylindrical shape. The inner case is fitted into the outer case. The inner case is filled therein with an adsorbent in a granular form. The inner case includes a first end and a second end. The connecting port connects an inside and an outside of the outer case to each other. The sealing member is provided to the second end of the inner case located opposite to the first end leading to the connecting port. The sealing member seals a gap between the outer case and a joining portion of the inner case. The joining portion joins the inner case to the outer case.

Abstract: A canister is mounted on a vehicle and comprises at least one chamber, an inflow port, an atmosphere port, an outflow port and elongated adjusting parts. The inflow port allows evaporated fuel to flow into the at least one chamber from a fuel tank of the vehicle. The outflow port allows the evaporated fuel adsorbed by an adsorbent to flow out towards an engine by air from the atmosphere port. The adjusting parts are arranged with the adsorbent in an object chamber, which is at least one of the at least one chamber.

Abstract: A canister includes at least one chamber in which an adsorbent to adsorb fuel vapor is arranged, an inflow port, an atmosphere port, an outflow port, and an adsorbent agglomerate. The adsorbent agglomerate is arranged in a specific chamber. The adsorbent agglomerate is a mass of a fibrous adsorbent. The specific chamber is one of the at least one chamber. The adsorbent agglomerate includes, on its outer surface, first and second surfaces intersecting with a flow direction of a fluid, and the second surface is positioned on a side opposite to the first surface. The adsorbent agglomerate includes at least one vacant space formed in the first surface and/or the second surface, and the at least one vacant space extends along the flow direction to a bottom located inside the adsorbent agglomerate.

Abstract: Provided is a canister that makes it possible to reduce production costs. One aspect of the present disclosure is a canister. The canister includes an outer case including a charge port that takes in an evaporated fuel, a purge port that discharges the evaporated fuel, and an atmosphere port open to the atmosphere, an inner case arranged inside the outer case, the inner case having an inner space to which the atmosphere port is connected, a first adsorption chamber arranged in the inner space of the inner case, and a second adsorption chamber arranged between the first adsorption chamber and the atmosphere port in a flow path of the evaporated fuel in the inner space of the inner case. A cross-sectional area perpendicular to a gas flow direction in the second adsorption chamber and a cross-sectional area perpendicular to a gas flow direction in the first adsorption chamber are different.

Abstract: A canister, mounted in a vehicle with an engine and including one or more chambers, includes adsorbents, an inflow port, an atmosphere port, an outflow port, and an adjusting member. The adjusting member is placed in a target chamber of the two or more chambers together with a corresponding adsorbent of the adsorbents. The target chamber is provided with a cushioning area located adjacent to at least one port of the ports. Two or more rod-shaped portions have first and second cross-sections orthogonal to a flow direction of an atmosphere and a fuel vapor. The first cross section is formed in the cushioning area, and the second cross-section is formed at a position distanced from the at least one port relative to the cushioning area. The first cross-section has a smaller area than an area of the second cross-section.

Abstract: A canister configured to adsorb evaporated fuel generated in a fuel tank of a vehicle includes a plurality of lumpy adsorbents and an atmosphere port. The plurality of lumpy adsorbents are arranged to be aligned in a flow direction of the evaporated fuel in a flow path through which the evaporated fuel passes, and adsorb the evaporated fuel. The atmosphere port is provided at an end of the flow path, and is open to atmosphere. The plurality of lumpy adsorbents at least include a first lumpy adsorbent and a second lumpy adsorbent adjacent to each other. The first lumpy adsorbent includes at least one protrusion protruding from a surface of the first lumpy adsorbent facing the second lumpy adsorbent. The at least one protrusion forms a gap between the first lumpy adsorbent and the second lumpy adsorbent around the at least one protrusion.
