Elementary Hydraulic Systems.
The simplest hydraulic system is perhaps the hydraulic shock absorber which consists of a pump (piston) and resistance. Another elementary type of system is the hydraulic weighing machine, which consists of a non- continuous pump element (piston or diaphragm) and pressure gauge.
Other elementary systems consist of a jack, transmission line, and a pump of the non-continuous type without control gear, although valves may still be present for secondary purposes. Systems of this type are used for remote transmission of manual or pedal effort or motion, or for remote transmission of instrument indication. The simplest best known system of this type is the hydraulic brake.

Hydraulic Machines. Water tap.
1. Remember the following words:
Handle - ручка Tap - кран
Clockwise - за годинниковою стрілкою
Anti-clockwise - проти годинникової стрілки
Bolt - болт Washer- прокладка Hole - отвір
2. Read and translate the text.
Water tap
When you turn the handle of the water tap clockwise, the water stops.
When you turn it anti-clockwise, the water pours out of the tap again. How does this work?
The tap has a handle on the top, and inside there is a bolt and a washer is over a hole.
When you turn the handle clockwise, this makes the bolt move downwards. The washer then covers the hole and stops the water.
When you turn the handle anticlockwise, the bolt moves upwards and the washer uncovers the hole again. This lets the water flows through the tap again.
