Abstract
222,889. Sauser Akt.-Ges., (Assignees of Wydler, H.). Oct. 5, 1923, [Convention date]. Vacuum apparatus.- Suction apparatus for raising fuel &c. from a low - level tank to a high-level vessel 14 supplying a carburetter &c. comprises a vacuum vessel 13 communicating with the vessel 14 by a siphon 25 and connected by a pipe 2 to the low-level tank and by a pipe 2a to a source of suction, such as the engine manifold. The vessel 14 is normally open to atmosphere, and the vessel 13 is connected to the pipe 2<a> by a channel 19 controlled by a ball valve 17 and a float valve 18. During the suction period liquid enters the vessel 13 and raises the float valve 18 to cut' off the suction. At the same time a vacuum is produced in a chamber 22 through a channel 20 and moves a diaphragm 21 carrying a valve 28 controlling the admission of atmospheric pressure to the vessel 13 through channels 29, 30, 31. The discharge leg of the siphon is connected to the chamber 22 by a. pipe 24 so that, when air is admitted to the vessel 13, the liquid flows through the siphon into the vessel 14. When the liquid in the vessel 14 lifts the float valve 23 in the pipe 24, suction is cut off from the siphon and atmospheric pressure in the vessel 13 keeps the valve 18 closed. When the liquid level in vessel 14 falls sufficiently to open the valve 23, atmospheric pressure enters the chamber 22 through the pipe 24, closing the air valve 28 and opening the valve 18, so that another cycle of operations begins. In another form, the needle valve 28 is replaced by a piston valve provided with channels for the passage of air to the channel 29, and the pipe 2a opens into a chamber above the diaphragm, which has a small aperture to connect this chamber to the chamber 22. In another form, the siphon is in the form of two concentric pipes. Two alternately-acting vessels 13 may be arranged in one receiver 14, the two air valves being connected by a pivoted beam so that when one valve is open the other is closed.
