Break-away concentric hose coupling |
摘要 |
A vapor recovery breakaway hose coupling for use in conjunction with a vapor recovery nozzle and for application within a fuel line, that prevents untimely decoupling, that incorporates a secondary seal that is located between the fuel and vapor passages to maintain clean o-ring sealing and sliding surfaces by preventing fuel and/or contaminates from contracting the primary fuel to vapor o-ring when the valve is in a non-emergency situation, an interference bump is incorporated which imparts a shock to the fuel check valve during separation and unbalanced check valve springs that maintains a static seal to reduce o-ring fretting, and primary fuel to vapor o-ring relocation.
