ylinder, this water enters the lower or hollow portion ofthe inverted U-shaped collar and firmly presses the leatheragainst both the piston P and the surface of the g-roove,thus preventing any escape of water from the cylinder. In consequence of this great improvement in the machine,it is very… … Fig. 8. i in Fig-. 8, which is a simple sketch of the essentials of theforce-pump. When the piston p rises, a valve, e, in thepipe dipping- into the reservoir B, opens upwards andallows the water to fill the cylinder J and to flow through0 to the valve i.
