Abstract: A fuel tank assembly has a fuel tank with a fuel flow control device disposed at least partially in the fuel tank, and which communicates with a fuel filler pipe through which volatile fuel is added to the fuel tank. In one embodiment, the fuel flow control device includes a fill tube that controls the manner in which fuel enters the fuel tank, preferably to reduce generation of fuel vapor when fuel is added to the fuel tank. In one embodiment, the fill tube is a flexible tube and includes a float adjacent to an outlet end of the fill tube so that the outlet end of the tube is responsive to the level of liquid fuel in the fuel tank for at least some levels of fuel in the fuel tank.

Abstract: A two-way, inline, hydraulic valve through which fluid can flow in reverse and in forward directions has a reverse flow passage including a check valve preventing forward direction fluid flow therethrough. Forward direction fluid flow is controlled by a movable, spring-biased, normally closed, spool valve having one end exposed to forward direction fluid pressure and an opposite end forming a piston acting in a cylindrical cavity containing a volume of fluid. Movement of the spool valve to open position in response to forward direction fluid pressure sufficient to overcome the spring bias causes the volume of fluid to be forced from the cavity through a restricted passage, thereby providing a time delay in the opening of the two-way valve for forward direction fluid flow. In an alternative embodiment, a sleeve valve mounted on the spool valve provides a by-pass permitting forward direction fluid flow under abnormally low forward direction fluid pressure.
