Subclass | Title |
---|---|
1/00 | Pumps using positively or negatively pressurised fluid medium acting directly on the liquid to be pumped (using only negative pressure F04F 3/00; jet pumps F04F 5/00; siphons F04F 10/00) |
1/02 | Pumps using positively or negatively pressurised fluid medium acting directly on the liquid to be pumped (using only negative pressure F04F 3/00; jet pumps F04F 5/00; siphons F04F 10/00) using both positively and negatively pressurised fluid medium, e.g. alternating |
1/04 | Pumps using positively or negatively pressurised fluid medium acting directly on the liquid to be pumped (using only negative pressure F04F 3/00; jet pumps F04F 5/00; siphons F04F 10/00) using both positively and negatively pressurised fluid medium, e.g. alternating generated by vaporising and condensing |
1/06 | Pumps using positively or negatively pressurised fluid medium acting directly on the liquid to be pumped (using only negative pressure F04F 3/00; jet pumps F04F 5/00; siphons F04F 10/00) the fluid medium acting on the surface of the liquid to be pumped (F04F 1/02 takes precedence) |
1/08 | Pumps using positively or negatively pressurised fluid medium acting directly on the liquid to be pumped (using only negative pressure F04F 3/00; jet pumps F04F 5/00; siphons F04F 10/00) the fluid medium acting on the surface of the liquid to be pumped (F04F 1/02 takes precedence) specially adapted for raising liquids from great depths, e.g. in wells |
