HYDRAULIC SHOCK DAMPERS. X. 235 X. 8520 There are some particulars in connection with the above, which form a combination of parts which are unusual, and a copy of the design (blue print) should be sent to Mr. Claremont, with descriptive notes as to where it varies from those already made by otherpeople :- (1) Double unequal damping. (2) Forced filling. (3) Low pressure restriction to expel air, with (4) Ball valve to admit oil freely in case of deficiency, this drawing from lowest part of reservoir. R.{Sir Henry Royce} | ||
