Abstract: A pump includes a substantially tubular housing having an inlet end and an outlet end and defining a central axis and a chamber within the body portion, and a movable valve assembly slidably received within the housing for movement in the direction of the central axis. The pump also includes a handle assembly slidably disposed at least partially around an outer circumference of the housing for movement in the direction of the central axis, the handle assembly being substantially annular ring-shaped, and the handle assembly including a grip engageable by a hand of an operator for manually sliding the handle assembly, the handle assembly being coupled to the movable valve assembly, manual movement of the handle assembly along the central axis causing corresponding movement on the movable valve assembly along the central axis.

Abstract: A method of assembling selected modular ratchet cap assemblies. In one aspect, the method includes the acts of providing identical threaded portions, providing identical cover portions, providing a first vent module, providing a second vent module different from the first vent module, selecting the first vent module and coupling together the first vent module with one of the identical threaded portions and one of the identical cover portions to form a first cap assembly, and selecting the second vent module and coupling together the second vent module with another one of the identical threaded portions and another one of the identical cover portions to form a second cap assembly. In other aspects, the method includes assembling first and second cap assemblies with identical cover portions and threaded portions, but having different pawl members providing different cap-installing torque limits.

Abstract: A fuel cap operable to close an opening of a fuel tank. The fuel cap includes an outer shell having a protrusion and a shell locking member. The fuel cap includes a detection mechanism for sensing a level of fuel within the tank. The fuel cap further includes an assembly component engageable with the outer shell to support the detection mechanism on the outer shell. The assembly component defines a groove operable to receive the protrusion. Additionally, the assembly component includes a component locking member. The outer shell and the assembly component are engageable with one another by a relative axial movement followed by a relative rotational movement about an axis. Once engaged, the outer shell and the assembly component are fixed against disengagement by engagement of the shell locking member and the component locking member.

Abstract: A cap for selective attachment with a threaded opening includes an outer cover and an inner portion, the inner portion lying at least partially within the outer cover and having threads engageable with the threaded opening and a set of circumferentially-spaced teeth arranged to selectively receive torque from manual rotation of the outer cover. A slider in constant driving engagement with the outer cover is selectively engageable with the teeth of the inner portion to transmit torque from the outer cover to the inner portion. An actuator is provided to actuate the slider into and out of engagement with the teeth of the inner portion. A lock is provided accessible from outside the outer cover and being coupled to the actuator. A locked state of the cap is one in which the slider is removed from engagement with the teeth of the inner portion by the lock and actuator and an unlocked state of the cap is one in which the slider is engaged with the teeth of the inner portion.

Abstract: A tank assembly and fuel system for an engine having an engine intake. The fuel system may comprise a tank housing defining an interior and an exterior and an opening between the interior and the exterior, a liquid being containable in the interior, vapor being produceable from the liquid, a closure housing connectable to the tank housing to selectively close the opening, a vapor path from the tank interior to the engine intake, and adsorption media for trapping harmful components in the vapor, the adsorption media being supported in the vapor path and being positioned in the vapor path between the tank interior and the engine intake.

Abstract: A tank assembly and a closure device for a tank assembly. The tank assembly may comprise a tank housing defining an interior and an exterior and an opening between the interior and the exterior, a liquid being containable in the interior, vapor being produceable from the liquid, a flow path being defined between the interior and the exterior, a closure housing connectable to the tank housing to selectively close the opening, and adsorption media supported by at least one of the tank housing and the closure housing, vapor being routed along the flow path from the interior of the tank assembly, through the adsorption media and to the exterior of the tank assembly. In some aspects, the adsorption media is supported by the closure housing. In some other aspects, the tank housing includes a receptacle portion having a receptacle interior, the receptacle portion defining the flow path, and the adsorption media is supportable in the receptacle interior.

Abstract: A vent structure at least partially defining a passageway between the inside of a fuel storage tank and the outside atmosphere includes a separator membrane. The separator membrane is positioned within the vent structure configured to block liquid fuel in the storage tank from reaching the outside atmosphere through the passageway. The separator membrane is permeable by air. The vent structure may be in the form of a cap or a remote vent, or it may be provided substantially within the fuel storage tank. The vent structure may be provided as part of a fuel evaporative emissions system for a vehicle or motor-driven power equipment.
