摘要:
An electro-pneumatic valve assembly includes a valve having a valve housing (30) and a poppet (32) and a solenoid valve having an actuator housing and a valve body. The valve housing (30) has a wall that defines a valve inlet that is arranged to receive a fluid flow from a pressurized container and defines a valve outlet (62) and a first port (60). The poppet (32) is disposed within the valve housing (30) and is movable between a first position and a second position. The actuator housing defines an opening. The valve body has a first wall that defines an inlet that is fluidly connected to the first port and a second wall that defines an outlet that is fluidly connected to the second port (66).

A method of operating an inflation system and an inflation system are provided. The method includes recognizing that the inflation system is activated or actuated by a user, supplying current to an electromagnet (63) of a solenoid valve (60) of the inflation system such that an armature-valve element (62") of the solenoid valve is moved to an open position, wherein movement of the armature valve element to the open position actuates an actuator housing that in turn causes a normally-closed valve element of a valve housing of the inflation system to open, and ceasing current supply to the electromagnet once the actuator housing is actuated.

An auto/manual gas inflator incorporating a gas cylinder and an auto cap. A first indication mechanism is provided for indicating the status of the gas cylinder which is visible through a first window in the inflator housing and a second indication mechanism is provided for indicating the status of the auto cap through a second window in the inflator housing. The auto cap in one embodiment uses a dissolvable pill for automatic inflation. A manual activator, such as a lanyard assembly can be used for manual inflation. In either activation method, a pierce pin is moved upward to break the cylinder's seal and release the gas contained within the cylinder.

The present invention utilizes the resilient force (i.e. the force to deform when pressure is added and to return to the original shape when the pressure is removed) of an elastic member or bias member. A large pressure if added in advance to the elastic member or bias member disposed in a preserver body to set the preserver body in a thin and flat state. In an emergency, the resilient force of the elastic member or bias member causes water or air to be sucked into the preserver body. The volume of the preserver body is expanded by the air sucked in due to the resilient force of the elastic member or bias member or by gas generated by a chemical reaction between the sucked-in water and a foaming agent. The increased volume causes the preserver body to float, thereby enabling a wearer to breathe. As another example, a liquid bag provided in the preserver body can be pulled or pressed from the outside to rip the liquid bag or a bias member in a latched state can be removed from the latched state to rip the liquid bag as a result of the resilient force, thereby generating a case caused by a reaction between a reactive fluid in the liquid bag and a foaming agent to increase the total buoyancy of the preserver body and float a person.

The invention is directed to an airbag system and, more particularly, to such a system employed as a rescue or life-saving system to enable a person to survive an avalanche. In a particular embodiment, the invention relates to an airbag system utilized with a backpack to be worn by a skier, snowboarder, hiker, or snowmobiler, for example. Instead of relying upon compressed gas cartridges or cylinders to inflate the airbag(s), the invention inflates the airbag(s) with ambient air only. In a particular embodiment, air is supplied to the airbag by means of a battery-powered electrical motor.

The invention relates to a high lift system for an airplane, comprising: one or more high lift flaps (14a, 14b); a control device (60, 160) having a control function for generating position commands for setting the adjustment state of the high lift flaps (14a, 14b); a drive device (63, 163) coupled to the high lift flaps (14a, 14b) and is designed such that it adjusts the high lift flaps (14a, 14b) between a retracted position and an extended position on the basis of control commands, wherein the control function creates position commands based on input values and sends them to the drive device (63, 163) for adjusting the high lift flaps (14a, 14b). The control function comprises a function for automatically retracting the high lift flap (14a, 14b) during flight, which creates a control command in a flight state in which the high lift flap (14a, 14b) is in an extended position, taking into consideration an engine thrust and a minimal flight altitude, after the high lift flap (14a, 14b) is retracted.
