Abstract: A valve mechanism for a gas spring suspension system that equalizes the gas between positive and negative gas chambers when the pressure in the negative gas chamber exceeds the pressure in the positive gas chamber. The suspension system includes a tube, a piston assembly slidably displaceable along the tube and a valve mechanism. The piston assembly separates the tube into the positive gas chamber and the negative gas chamber. The valve mechanism is configured to permit gas flow between the positive and negative gas chambers when the gas pressure in the negative gas chamber exceeds the gas pressure in the positive gas chamber.

Abstract: An actuator apparatus controls a valve mechanism of a suspension system. The apparatus includes a valve actuating assembly and an adjuster assembly. The valve actuating assembly is operatively connected to the valve mechanism and is operable between at least two rider-selectable positions to adjust the valve mechanism between various suspension settings. The adjuster assembly is operatively connected to the valve actuating assembly for adjusting the damping characteristics corresponding to at least one of the positions of the valve actuating assembly independently of the damping characteristics corresponding to another position of the valve actuating assembly.

Abstract: An aircraft window shade includes protective transparent window panels, a shade driven by an electric motor, an integral control panel, and support for remote operation. The shade uses dual sprocket drive for positive shade positioning, low wear, and low parts count. The moving shade element remains substantially flat, curving slightly during some phases of positioning. The apparatus replaces a conventional interior window panel and a manual shade with slight change in overall mechanism thickness and weight. Control electronics in the shade can accept a command from a cabin attendant's console to override the local setting and move the shade to a required position, such as fully open for takeoff. The shade supports use of two or more independent shades, each of which can be made of dimming (transparent), diffusing (translucent), or light blocking (opaque) material. The shade is compatible with electrochromic transmittance control technology.

Abstract: A gas spring suspension system that adjusts the spring rate as the travel is adjusted. The suspension system includes a frame, a pressure chamber, a compression piston assembly, an adjustment assembly, a piston tube, and a shaft. The piston tube is operatively connected to the adjustment assembly and the compression piston assembly, and the compression piston assembly is configured to slidably displace along the piston tube to change the pressure in the pressure chamber. The adjustment assembly is associated with the frame and is operable to axially position the piston tube and, in turn the compression piston assembly, relative to the frame to adjust the travel of the suspension system. The shaft is configured to be variably positionable within the pressure chamber in response to axial displacement of the piston tube and the compression piston assembly by the adjustment assembly, the variable positioning of the shaft within the pressure chamber changing the pressure therein.

Abstract: 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.
