• The height to which the water can be forced in the pipe depends upon the size and construction of the pump and upon the force with which the plunger can be moved. 伯莎M.克拉克. 科学通论.
• As the wheel rotates, its motion is communicated to a mechanical device which makes use of it to raise and lower a plunger, and hence as long as the wind turns the windmill, water is raised. 伯莎M.克拉克. 科学通论.
• When the piston moves downward as in (3), the valve in the pipe closes by its own weight, and the air in the cylinder escapes through the valve in the plunger. 伯莎M.克拉克. 科学通论.
• This consists of a large cast-iron cylinder fitted with a plunger, which is made to work water-tight therein by means of suitable packing. 威廉·亨利·杜利特. 世纪发明.
• Hence, even when the plunger is moving upward, water is forced through the pipe because of the pressure of the compressed air. 伯莎M.克拉克. 科学通论.
• In (2) the plunger is being raised and is lifting the column of air that rests on it. 伯莎M.克拉克. 科学通论.
• This was a governor, called the dash pot--a small cylinder partially filled with oil, and in which was a plunger. 佚名. 神奇的知识之书.
• C is an air compressing pump, whose plunger descending compresses the air and forces it out through valve I, pipe 2, and coil 3. Edward W. Byrn. 十九世纪发明进展.
• In (5) the process of (3) is being repeated, but water instead of air is escaping through the valve in the plunger. 伯莎M.克拉克. 科学通论.
• No doubt scale has something to do with the matter; he was a record, the record plunger; but there is something more in it than that. 赫伯特·乔治·威尔斯. 世界史纲.
• Water is pumped into the cylinder until the plunger is raised to its full height within the cylinder, when the supply of water is cut off by the automatic operation of a valve. 威廉·亨利·杜利特. 世纪发明.
• It shows a little solenoid arrangement, with one end of the plunger attached to the diaphragm of a speaking or resonating chamber. 弗兰克·刘易斯·戴尔. 爱迪生的生平和发明.
• The continuing action of the plunger is such as to screw the wire into the back. 威廉·亨利·杜利特. 世纪发明.
• An upward motion of the plunger allows water to enter the cylinder, and the downward motion of the plunger drives water through _E_. 伯莎M.克拉克. 科学通论.
• Water is supplied to the two plungers under a pressure of 7,000 pounds per square inch, giving it a maximum capacity of 15,000 tons. 佚名. 神奇的知识之书.
