摘要： A vapor storage canister has an improved carbon bed loading pressure maintenance mechanism. A pressure plate is driven up indirectly, through a threaded shaft turned by a radially wound spiral spring, rather than by an axially compressed helical spring. This takes better advantage of the space available between the carbon bed and the lower end of the canister.

摘要： A tank vapor vent valve assembly uses a spring loaded sealing flapper door located below a normally open float chamber. The flapper door spring is specifically designed to open when the tank pressure falls, allowing make up air to pull the flapper door down and draw in make up air through the canister inlet.

摘要： A vapor venting means for a vehicle fuel system in which one ball valve serves both the close off function between fuel fills, and the automatic shut off function during fuel fill, but does not depend upon falling under its own weight in order to open the vapor vent path to the canister. The ball valve is indirectly loaded against a lower valve seat, which is spaced from an upper spring seat, through the use of a spring loaded carrier that normally traps the ball valve against the lower seat. Then, when the nozzle is inserted, the carrier is pushed up so that the ball valve is freed without having to fall under its own weight. Since the ball valve is not confined or limited, it can also float up against the upper spring seat in the event of fuel overfill.
摘要翻译：一种用于车辆燃料系统的蒸汽排放装置，其中一个球阀既用于燃料填充之间的关闭功能，又用于燃料填充期间的自动关闭功能，但不取决于在其自重下落下以打开蒸汽通向罐的通风道。球阀通过使用通常将球阀截留在下座上的弹簧加载的载体而间接地装在与上弹簧座间隔开的下阀座上。然后，当喷嘴插入时，托架被推上，使得球阀被释放而不必落入其自重。由于球阀不受限制或限制，因此在燃料溢出的情况下也可以浮起来抵靠上弹簧座。

摘要： A fuel tank protection valve includes a pendulum type weight that hangs within a bearing socket located below the vent line opening in a fuel tank vapor collection dome. When the vehicle tilts significantly from the horizontal, the weight pivots within the socket, kicking a float ball up to seal the vent line opening. The closing angle of the valve may be easily varied, without changing the shape or size of the bearing socket, by varying the offset from the socket pivot point of the bearing socket of an extension of the weight that actually engages the float ball.

摘要： A fuel pressure regulator base has a fuel chamber adapted for plug-connection directly to the fuel rail to receive fuel from the rail, a flexible diaphragm closes the chamber, a cover forms a pressure chamber with the diaphragm, and the pressure regulator base further has a pressure passage adapted for plug-connection directly to the inlet manifold and extending to the pressure chamber to transfer the manifold pressure to the pressure chamber. The diaphragm thereby senses the difference between the fuel pressure and the manifold pressure and operates a valve to discharge excess fuel from the fuel chamber and the fuel rail and thus maintain the fuel in the rail at the desired pressure.
