摘要
| 描述 | Drawing of Robert Boyle's air pump. It illustrates: a 28.4-litre glass "receiver" (A) connected by a stopcock (N) to a 36-cm-long brass pumping cylinder, through which a padded piston (4) was drawn by a toothed shaft (5). To operate the air pump, first the stopcock was closed, and the piston was cranked down. Then, with the stopcock opened, part of the air in the receiver moves into the cylinder. Then the stopcock was closed, the brass plug (R) removed, and the piston raised, expelling air from the cylinder. As the procedure was repeated, the air pressure in the receiver decreased.
