Title: Improvements in liquid depth indicating device
IPC: G01F23/16
Filed: 1929-07-09
Abstract: 332,391. Lewis, W. W. July 9, 1929. Indicators actuated by pressure of head of liquid.-In a depth indicator for the fuel tank of a motor vehicle, of the kind in which pressure is transmitted to a gauge through an air pipe dipping into the liquid, the air in the pipe is replenished by means of a plunger c which rises and falls due to the movement of the vehicle. On the rising movement, liquid is drawn in through opening f<1>, past valve g, and on the falling movement is forced through pipe h into a widened portion k<1> of a pipe k. A small quantity of air is thereby trapped and carried down the pipe k, and discharged beneath the open end of the air pipe a leading to the gauge. The pipe a is thereby maintained full of air. In a modification, Fig. 2, not shown, the pipes h, k are replaced by a single inverted U-tube having a small hole at the top. In another modification, Fig. 3, not shown, the pipe h is omitted and the piston is made a loose fit so that liquid passes around it to the upper end of the tube b and overflows into a pipe having a small orifice at the top, by which air is entrained and finally delivered below the pipe a.
