摘要： An extended flexible polyurethane inner hose defines a fuel supply passage and is surrounded by an unbonded braided nylon reinforcement filament. The inner hose extends within a molded polyurethane and flexible corrugated outer hose which defines an annular fuel vapor return passage around the inner hose. Corresponding end portions of the hoses are connected to a fuel dispensing nozzle by a tubular metal inner coupling member, a tubular nylon outer coupling member, and a nylon nut. A small flexible fuel evacuation tube extends within the lower portion of the vapor return passage adjacent the inner hose, and an annular rotary coupling or union member and ring seals are confined between the inner and outer coupling members to define a fuel evacuation passage which connects the evacuation tube to a corresponding tube within the dispensing nozzle. The opposite end portions of the inner and outer hoses are connected by corresponding tubular coupling members to a fuel dispensing pump, and a support yoke, clamping ring and nut cooperate to prevent rotation of the hoses after they are connected to the dispensing pump. The nylon outer coupling members and nuts are carbon filled to be electrically conductive and are connected by a static wire helically wound around the inner hose.

摘要： A fuel storage system is provided including at least one storage tank, an exhaust port, a filter system, and at least one pump positioned to cause fluid to pass through a filter input port. The filter system comprises a filter input port coupled to the fluid vent port, a fuel vapor duct defining a flow path extending from the filter input port to a primary filter output port and a secondary filter output port partitioned from the fuel vapor duct by the permeable partition. At least one pump is positioned to cause fluid to pass through the filter input port. The storage tank and the pump are arranged such that major portions of the system operate below atmospheric pressure such that system leaks do not lead to release of fugitives from the fuel into the atmosphere.

摘要： A fuel storage system is provided including a storage tank, an exhaust port, a filter system, a primary pump, and at least one secondary pump. The storage tank includes a fuel delivery port, a fluid vent port, and a pollutant return port. The filter system includes a filter input port coupled to the fluid vent port, a fuel vapor duct, and primary and secondary filter output ports. The fuel vapor duct defines a flow path extending from the filter input port to the primary filter output port. The primary filter output port is coupled to the pollutant return port. At least a portion of the fuel vapor duct forms a permeable partition designed to pass a non-pollutant component of fluid within the fuel vapor duct through the permeable partition and designed to inhibit passage of a pollutant component of fluid within the fuel vapor duct through the partition. The secondary filter output port is partitioned from the fuel vapor duct by the air-permeable partition and is coupled to the exhaust port. The primary pump is positioned to cause fluid to pass from the filter input port to the primary filter output port. The secondary pump is positioned to cause the non-pollutant component within the fuel vapor duct to pass through the permeable partition to the secondary filter output port and the exhaust port.
