The present invention relates to a system and assembly for refilling a reservoir with liquid dispensed from a dispenser, in particular, but not exclusively, to a system and assembly for the substantially leak-free refilling of the reservoir of a smoking-substitute device with a liquid comprising nicotine from a refill dispenser. The assembly is configured to provide a gas communication pathway through the assembly and physically separate from the liquid communication pathway for venting gas from an end of the assembly proximal the first aperture to an exterior of the assembly responsive to the movement of the assembly to the secured and open configuration, the assembly configured to close the gas communication pathway in the unsecured and closed configuration

A filling system for an electronic cigarette (10) is disclosed in which a nozzle (38) of a liquid dispenser (80) contains a plunger (62) which is biased by a spring (60) into a closed position in which liquid is prevented from flowing through the nozzle (38). In use the nozzle (38) is inserted into an open end (42) of a liquid reservoir (34) for an electronic cigarette containing an air tube (32). The plunger (62) engages with the end of the air tube (32) blocking the air tube (32) and opening the liquid flow path through the nozzle (38). The arrangement of the plunger (62) and nozzle (38) is such that operation of the plunger (62) only occurs when the nozzle (38) engaged within a liquid reservoir (32). A membrane (96) can be provided to prevent leakage from the liquid reservoir (34) when the nozzle (38) is disengaged.

A nozzle for dispensing fluid including a nozzle body having a fluid path therein through which fluid is configured to flow in a downstream direction. The nozzle further includes a valve having a valve body positioned in the fluid path and movable between a closed position wherein the valve body sealingly engages a valve seat to generally block fluid from flowing therethrough, and an open position wherein the valve body is spaced away from the valve seat to generally allow fluid to flow therethrough. At least part of a surface of the valve body positioned upstream of the valve seat is configured to be fluidly isolated from a pressure of fluid in the fluid path upstream of the valve seat when the valve is in the closed position.

A fuel dispensing nozzle, incorporating a uniquely shaped gasket for the poppet valve, generally of truncated shape, enhances the flow of fuel through the nozzle when actuated. A handle lever for the nozzle, which is designed having an elongated and enlarged end, includes elongated slots, that are pivotally pinned through both the latch plate, and the handle link, in order to reduce the space between the interconnection between the front of the latch plate to the bottom of the automatic shutoff stem, such that by lessening the distance between these components, thereby reducing the fulcrum point for the calculation of the force necessary to open the nozzle by raising its handle lever, and reduces the force necessary to achieve nozzle opening and actuation, to less than 5 lbs pressure during usage and application.

Filling nozzle for delivering a fluid, comprising an inlet (13) for connection of a fluid feed line, an outlet (14), a main conduit (15) connecting the inlet to the outlet, a main valve device (16) for controlling a flow of fluid through the main conduit (15), a control lever (17) for actuating the main valve device (16), an automatic safety shut-off designed to move the main valve device (16) to a closed position independently of a position of the control lever (17) when a fluid pressure at the inlet (13) falls below a minimum value, and comprising a preloading device (18) which preloads the main valve device (16) into the closed position and effects a variable opening cross-section of the main valve device (16) depending on a fluid pressure at the inlet. According to the invention, the preloading device (18) is designed to produce a discontinuous opening characteristic of the main valve device (16) in such a way that a closing force acting on a valve body (20, 20, 20, 22) of the main valve device is reduced in a first opening cross-section range extending from the closed position of the main valve device (16) to a limit opening cross-section.
