Fuel Cartridge with Connecting Valve

Номер: US20120012211A1
Автор: Andrew J. Curello, Floyd Fairbanks, Paul Adams
Принадлежит: BIC SA

A shut-off valve or connecting valve capable of connecting a fuel supply to a fuel cell is disclosed. The valve comprises a first valve component and a second valve component. Each valve component has an outer housing and a biased slidable member disposed inside the housing forming an internal seal. During the connection process, the two valve components establish an inter-component seal. Afterward, in one suitable embodiment the slidable member moves inward and opens the internal seal in the valve component to establish a flow path. In another embodiment, the slidable member moves inward and exposes a first filler and the first filler abuts a second filler in the other valve component to establish a flow path. In other embodiments, at least one valve component is sized and dimensioned to limit access to the internal seal.

Cartridge Hydraulic Coupler and Method of Use

A male and female set of hydraulic coupler cartridges mate such that one part of the coupler can be left in place, e.g. the female coupler, with the other portion of the coupler, e.g. the male coupler, being removably connected or disconnected. Valves within each cartridge comprise an actuator and springs within each cartridge urge the valves into a closed, sealing position. When the cartridges mate, spring and/or fluid pressure within the cartridges operates to either allow or disallow fluid flow. Once the cartridges are mated, their respective springs are partially compressed and movement of one of the valves operates to compress one spring and correspondingly decompress the other. The cartridges can therefore be mated and unmated, e.g. subsea, while fluid flow is prevented through them during the mating and unmating. 1.

Fluid coupling assemblies and methods are discussed. The fluid coupling assemblies include a first coupling member, a second coupling member magnetically engageable with the first coupling member, and a seal member disposed between a portion of the first coupling member and a portion of the second coupling member. A magnetic engagement of the first coupling member and the second coupling member unseals a fluid flow path therebetween. In certain examples, the first coupling member is sealed by a valve member and the second coupling member includes an activation member. When engaged, the valve member is moved from a closed position to an open position by the activation member, thereby unsealing the fluid flow path. A magnetic force between the first coupling member and the second coupling member can be chosen such that the members disengage when a predetermined fluid flow path pressure is reached.
