Description
Feb. 23, 1932. I DUBREUlL 1,846,852
LIQUID MEASURING APPARATUS Filed Feb. 28, 1929 UQP Patented Feb. 23, 1932 UNITED STATES GASTON DUBREUIL, OF LEYALLOIS-PERRET, FRANCE LIQUID MEASURING APPARATUS Application filed February 28, 1929, Serial No. 343,364, and in Germany March 6, 1928.
The present invention relates to liquid measuring apparatus and, more particularly, to those of the type adapted to be used with gasoline, oil and similar liquids.
One of the objects of the invention is to provide a measuring assembly having antifraud and safety features for guaranteeing the exact delivery of predetermined quantities of liquid.
Other objects will appear in the course of the deta led description now to be given with reierence to the accompanying drawing, in which the single figure represents, diagrammatically a section through one illustrative embodiment of the invention. 4
The general assembly comprises a pump a,-an air and gas separator b,a four-way valve c,a pair of measuring reservoirs 1 and 2,-a first safety locking system d,a second locking system e,and appropriate .conduits interconnecting pump a, separator b, valve 0 and reservoirs 1 and 2.
Pump a lifts liquid from a supply reservoir (not shown) into conduit a and discharges P through conduit a into a gas and air separator b fitted with a liquid reflector 6 a float 12 a valve 6 coacting with a gas discharge port 6, and a gas venting conduit 6 WVhen separator b is full, valve 6 moves into closing position and liquid passes upward into conduit f towards valve 0. Assuming the apparatus to be in the position shown in the drawing i. e; tank 2 being empty and locking system e in inoperative posit on. liquid will flow through valvepassage 0 into tank 1 and force the air contained in the latter through conduit 9 into tank 2.
When tank 1 is full, float valve 11 will move upward and close overflow opening 1, and pump a, cont nuing to work against valve 11,
will develop pressure in the liquid extending I between the discharge side of the pump and the top of tank 1. This pressure is transmitted through calibrated orifice 03 into conduit d thence to piston d working in cylinder (Z and finally'by means of a rod d? to a latch d which moves out of engagement with a notch in disc d and permits valve 0 to be rotated so as to (1) discharge tank 1 through passage 0 and (2) chargetank 2 through passage 0 The liquid being discharged enters conduit it, passes into chamber e and flows out through the delivery conduit. During its passage through chamber 6 the liquid acts on float c to move lever 6 into engagement with a notch in disc 6 thus preventing movement of valve 0 during the delivery operation.
If the pumping operation continues throughout the period that discharge is taking place, tank 2 will fill and the same series of operations may be repeated as described for tank 1.
From the foregoing it will be evident that (1) air cannot be introduced into the apparatus through the pump, intentionally or otherwise, without being eliminated by separator Z), (2) valve 0 cannot be operated until the tank being filled is completely full (effect of locking system 03), (3) valve 0 cannot be operated during a discharging operation (effect of locking system 6), (4) locking system d cannot be prematurely operated by irregularit es in the movement of pump a because of the refulatizing eflect exerted by calibrated orifice 0Z 'What I claim is V 1. In combination, a pump, a gas separator connected to said pump, a rotatable distributing valve communicating with the outlet 30 side of said separator, a pair of measuring tanks connected to said valve and adapted to alternately receive liquid from the separator, a discharge conduit adapted to receive liquid from either of said tanks, a first valve control means connected to said discharge conduit for preventing rotation of said valve during the flow of liquid therethrough, a second valve control means for locking said valve against rotation during the filling of either tank, and means operative to equalize variations in the pressures transmitted from the pump to said first valve control means.
2. An apparatus of the class described comprising a measuring tank, having a valve-controlled gas escape opening adapted to remain open until the tank is completely filled,apump for supplying liquid to said measuring tank,
a gas and liquid separator having its liquid inlet connected to saidpump and its liquid outlet connected to said tank whereby only substantially gas-free liquid is supplied to said tank, a valve for controlling the discharge of liquid from said tank, means looking said valve against opening until the tank is completely filled, and means responsive to the pressure of the liquid when the tank is full to release said lock to thereby permit opening the valve.
8. In combination, a pump, a gas and liquid separator having a liquid inlet connected to said pump, a gas outlet and a liquid outlet, a rotatable distributing valve communicating with said liquid outlet, a pair of measuring tanks connected to said Valve and adapted to alternately'receive liquid from the separator, each of said measuring tanks having a valve-controlled gas outlet, at discharge conduit adapted to receive liquid from either of said tanks, a first valve control means connected to said discharge conduit for preventing rotation of said valve during the flow of liquid therethrough, and a second valve control means for locking said valve against operation during the filling of either tank.
, l. In combination, a pair of measuring tanks, liquid supply means for said tanks, a. rotary distributing valve communicating with said liquid supply means and With said tanks, a discharge conduit adapted to receive liquid from either of said ta-nks,a first valve control means connected to said discharge conduit for preventing rotation of said valve during the flow of liquid thereto, and a secondvalve control means connected to said supply means for locking said valve against rotation during the filling of either tank.
In testimony whereof I hereunto affix my signature.
