Abstract
A suspension arrangement for use with aircraft landing gear, including an upper strut, a lower strut that is assembled with and telescopes relative to the upper strut and an oil reservoir within the struts. An adjustable valve assembly includes two interacting relatively movable members which divide the oil reservoir into two distinct sections and provides a restricted flow path for the flow of oil from one section of the oil reservoir to the other. Each of the relatively movable members includes apertures for the flow of oil from one section of the oil reservior to the other thereby to provide that flow path, the aperture being a series of windows in one member registrable with ports in the other member. A drive motor is mounted internally within at least one of the struts and moves the adjustable valve assembly so as to adjust the flow path area, which thus varies the flow of oil through the valve assembly and thereby varies the response of the suspension arrangement.
