Embodiment Construction

[0019] figure 1 is a schematic illustration of a refueling system 10 including a plurality of dispensers 12 . Each dispenser 12 includes: a dispenser body 14 ; a hose 16 connected to the dispenser body 14 ; and a nozzle 18 located at the end of the hose 16 . Each distributor 12 may include a vapor recovery valve 20 located substantially between the hose 16 and the distributor body 14 . Each hose 16 may be generally flexible and pliable so as to enable the hose 16 and nozzle 18 to be positioned where the operator desires to facilitate refueling.

[0020] Each distributor 12 is in fluid communication with a fuel / fluid storage tank 22 . For example, fluid conduit 26 extends from each vapor control valve 20 to storage tank 22 , while vapor conduit 24 extends from each vapor control valve 20 to storage tank 22 . figure 1 A schematic diagram of the connections between vapor control valve 20 , vapor conduit 24 , fluid conduit 26 and fuel storage tank 22 is provided. It should be ...

Abstract

A system includes a vapor recovery valve having a valve body with a fluid flow path and a vapor flow path. The fluid flow path and the vapor flow path are substantially fluidly isolated from each other. The vapor recovery valve also includes a vapor control valve located in the vapor flow path. The steam control valve is movable between a first position in which the steam control valve at least partially prevents the flow of steam therethrough, and a second position in which the steam control valve is in the same position as when the steam control valve is in the first position In contrast, steam control valves do not, or less, impede the flow of steam. The vapor recovery valve includes an actuator magnetically coupled to the vapor control valve. The actuator is configured such that sufficient fluid flow through the fluid flow path in a first direction will cause the actuator to move the steam control valve from a first position to a second position in a second direction that is the same as the first The directions are basically different.

Description

technical field [0001] The present invention relates to a vapor recovery valve, and more particularly to a magnetically actuated vapor recovery valve. Background technique [0002] In a typical gas station or other fueling system, fuel is pumped from a storage tank to a vehicle's fuel tank through a fuel dispenser. As fuel enters the vehicle's fuel tank, vapors from the interior of the vehicle's fuel tank are vented or forced out of the vehicle. Environmental laws and / or regulations often require capture of vented vapors. For example, a Class II vacuum-assisted vapor recovery system (i.e., a vapor recovery system used during vehicle refueling) may be required in order to capture and / or recover a certain percentage (eg, 95%) of the vapors expelled from the vehicle's fuel tank during refueling . The captured vapor is usually returned to the ullage space of the storage tank. [0003] Vacuum-assisted vapor recovery systems can use a vacuum source to help capture vented vapor...
