Abstract
Shock absorbing strut assembly comprising a telescopically extensible strut having therein an oil chamber of variable volume, a pressure accumulator comprising a spherical housing and a partition member provided in the housing and dividing the interior of the housing into two chambers, each of the chamber being divided by a flexible diaphragm into an oil compartment connected with said oil chamber and a gas compartment, the gas compartments being charged with gas of different pressures.
Claims5
Shock absorbing oleo assembly which comprises telescopically extensible strut means defining therein oil chamber means of variable volume, pressure accumulator means, said accumulator means comprising a housing, said housing having a pair of oil compartments therein, each of said compartments being separated by a partition and each of said compartments being in communication without any restriction with said oil chamber means in the strut means, at least two separated gas compartments in said housing, a pair of pressure responsive wall means in said housing which separate the gas compartments from said oil compartments, and each of which is exposed to its respective oil compartment, said gas compartments being respectively charged at different gas pressures, means for holding the pressure responsive means in the gas compartment of higher pressure against movement when oil pressure in the oil chamber means is below a predetermined value so that the gas pressure in the gas compartment of the higher pressure does not have influence on the oil pressure.
