...One revolution of the wheels takes place during a double stroke of one of the pistons, that is, while the piston moves from one end of the cylinder to the other, and back again. As there are two cylinders working at the same time, it follows, therefore, that, to... | |

...given to the valve, but while it travels from 1 to 2 the valve is opened and shut. Now, then, inasmuch as the piston moves from one end of the cylinder to the other for each semi-revolution of the cam, and inasmuch as the distance from a to 1 is the same as from 1... | |
