Fuel cartridge with flexible liner

A cartridge connectable to a fuel cell is disclosed. The cartridge comprises an outer casing and an inner flexible liner containing fuel for the fuel cell. The inner flexible liner may have an insert disposed inside the inner liner to facilitate the transport of fuel from the cartridge to the fuel cell. The insert minimizes the fuel that is trapped within the cartridge. The inner flexible liner can be used without the outer casing. The outer casing can be substantially rigid or flexible. The cartridge is also adaptable to receive byproducts from the fuel cell. The cartridge can also be pressurized to push fuel to the fuel cell. Unidirectional relief valves are also disclosed to prevent internal pressure in the cartridge from becoming too high or too low.

Lockout mechanism for a suspension system

A suspension system that includes a simplified lockout mechanism and an adjustable blow-off mechanism. The system includes a valve mechanism and a valve actuating assembly, a valve mechanism housing and a resilient member disposed between the valve mechanism and the valve mechanism housing. The valve mechanism is slidably mounted along the valve mechanism housing and it separates a first chamber from a second chamber. The valve actuating assembly operates the valve mechanism between open and closed positions. The resilient member is configured to be deformable by the valve mechanism as the valve mechanism is slidably displaced by an increasing pressure in the first fluid chamber. The sliding valve mechanism is configured to collide against the valve actuating assembly when a blow-off pressure is reached in the first fluid chamber switching the valve mechanism from the closed position to the open position.

Process for forging titanium-based material, process for producing engine valve, and engine valve

The invention provides a process for forging a titanium-based material comprises the steps of: preparing a titanium-based sintered workpiece including at least one of ceramics particles and pores in a total amount of 1% or more by volume, the ceramics particles being thermodynamically stable in a titanium alloy; and heating the workpiece to a forging temperature and forging the same. In the production process, the pores or the ceramics particles inhibit the grain growth during forging. Accordingly, it is possible to carry out the forging at a relatively high temperature at which the titanium-based material exhibits a small resistance to deformation. Moreover, the titanium-based material can maintain an appropriate microstructure even after the forging. Consequently, the impact value and the fatigue strength are inhibited from decreasing.

The stem is movable to and from a first position where the liquid seal is mated with the valve seat and a second position where the liquid seal is unseated from the valve seat. An actuator is connected to the distal end of the stem. The actuator is selectively movable to move the stem from the first position to the second position. A check-valve is adapted to block flow of liquid from the air outlet to the air inlet in the vent passage, and to allow flow of air from the air inlet to the air outlet in said vent passage. The valve optionally further includes a surge control device and / or a keeper for the check-valve seal.
