<p>The taxi instroke bypass valve assembly includes a slide axially movable relative to the restrictor assembly for opening and closing one or more bypass orifices in the restrictor assembly. The slide is held in the closed position whenever the landing gear mechanism is in a specified stroke range from fully extended by a secondary piston which is acted upon by the pressure in a precharged secondary chamber urging the secondary piston into engagement with a probe connected to the slide. At some point in the strut stroke, the pressure within the upper piston chamber of the landing gear will rise to that of the precharged secondary chamber. The secondary piston will then be stroked along with the main strut piston and the slide will move to the open position allowing fluid to bypass the main orifice, reducing the damping loads as the landing gear mechanism negotiates bumps during taxiing.</p> |
