  1. Answer the following questions:

    1. What is a pneumatic motor?

    2. What do you know about piston motors?

    3. What is a rotary vane motor?

    4. What is rotary motion vane type air motor?

    5. What is the difference between the rotary vane and the rotary motion vane type air motors?

    6. What do you know about small pneumatic motors?

    7. What do you know from the history of pneumatic motors?

  1. Complete the sentences with the appropriate words from the text:

    1. As more air is pumped into the chamber, the pressure increases and the piston begins to move down the _______.

    2. In order to achieve linear motion from compressed _______, a system of pistons is most commonly used.

    3. Essentially, piston motors are the same as hydraulic pumps except they are used to convert hydraulic energy into _______ energy.

    4. The vanes are extended to the housing walls using springs, cam action, or air pressure, depending on the _______ design.

    5. A _______ motor is a machine which converts potential energy in the form of compressed air into mechanical work.

    6. Reduction _______ create high torque levels with the lower amounts of energy input.

    7. The compressed air is pumped into an air tight chamber that houses the _______ of the piston.

  1. Make up word combinations from the following words, translate them into Ukrainian.

    1. pneumatic a) pump

    2. linear b) industry

    3. hydraulic c) motor

    4. reduction d) motion

    5. mechanical e) position

    6. original f) gears

    7. transportation g) work

  1. Finish the following sentences:

    1. Pneumatic motors have found widespread success …….

    2. A widespread application of small pneumatic motors …….

    3. Linear motion can come from either a diaphragm …….

    4. Stored energy in the form of compressed air …….

    5. As air is pumped into the chamber the force …….

    6. Engine air places the motor immediately beside the …….

    7. Small pneumatic motors offer greater power density …….

  1. Match the words with their definitions:

motor, gear, shaft, torque, transportation, engine, slot.

    1. A bar which turns, or around which a belt or wheel turns, to pass on power or movement from an engine to something driven by the engine.

    2. A long straight narrow opening or hollow place, especially in a machine.

    3. A piece of machinery with moving parts which changes power from steam, electricity, oil, etc., into movement.

    4. A part of a machine which has a special use in controlling a vehicle.

    5. The act of transporting or state of being transported.

    6. A machine that changes power, esp. electrical power, into movement, and is used for working other machines.

    7. Twisting force; power that produces rotation.

8. Decide whether the statements below are true or false:

1. Rotary motion vane type air motors are used to start small industrial diesel or natural gas engines.

2. Pneumatic motors generally convert the compressed gas to mechanical work though either linear or rotary motion.

3. Historically, many people have tried to apply pneumatic motors to the transportation industry.

4. Each slot of the rotor is fitted with a freely sliding rectangular vane.

5. Piston engines are often used in series of two, three, four, five, or six cylinders that are enclosed in a housing.

6. The rotating element is a slotted rotor which is mounted on a cylinder.

7. Another type of pneumatic motor, known as a rotary vane motor, uses air to produce linear motion to a shaft.
