Abstract
167,194. Houdaille, M. June 2, 1919. Dash-pots.-A check valve constructed so that when the valve is seated to prevent the flow of liquid it still allows air or gas to pass is applied to hydraulic shock-absorbers of the kind comprising a pair of ported vanes f, f<1> mounted on a spindle e and adapted to work in upper and lower compartments b, b<1> formed in a casing a by horizontal partitions. Communication is established between the two compartments through ports e<11> in the spindle, and each compartment communicates with a filling reservoir g through loose ball valves l, j. The valve seat for the valve l has bye-pass passages m of such dimensions as to permit air to pass while preventing the passage of liquid. Auxiliary devices may be provided, actuated manually or automatically, to vary the area of these passages.
