25,970. Sch³tt, J. H. Nov. 25. Direct air-pressure apparatus. - Consists of a process and apparatus. A vessel, such as a, immersed in the liquid to be raised from a well &c., is filled by atmospheric pressure and discharged by compressed air admitted from a reservoir f. The discharge is stopped before the liquid level in the chamber a reaches the foot of the rising pipe b, and the compressed air then in the vessel a is returned to the suction side of the compressor, which it thus assists in driving. In a modification, part of the air may be allowed to escape by the rising pipe. The admission of the air to the vessel a and its exhaust to the compressor are controlled by a pair of oppositelymoving valves, as at d, e.
