ABSTRACT:
A fuel vapor recovery canister in a motor vehicle fuel system comprising: adsorption means for releasably absorbing fuel vapor; an open-ended housing for the adsorption means, the housing comprising end closure means forming a fluid tight seal with an open end of the housing and having a first fluid flow port therethrough for communicating a flow of fluid into and out of the housing, and a second fluid flow port remote from the first and open to the atmosphere, wherein the first and second fluid flow ports are in communication with each other within the housing through the adsorption means; a first barrier means within the housing for separating the adsorption means from the first fluid flow port; second barrier means within the housing for separating the adsorption means from the second fluid flow port, the housing, first and second barrier means cooperating to contain the adsorption means; and biasing means, such as a coil spring, positioned intermediate the end closure means and the first barrier means for biasing the barrier means toward the adsorption means to place the adsorption means in compression.
