PNEUMATIC & HYDRAULIC

What is type of this cylinder

• Double acting cylinder

• Spring return cylinder

• Single acting cylinder

• 5/2 way double solenoid

The difference between single acting and double acting cylinders is:

• Single acting cylinders are smaller than Double acting cylinders

• Double acting cylinders have two pistons

• Work can be done in two directions in double acting cylinder unlike single acting cylinders.

Pneumatics is concerned with a system that uses:

• Oil

• Expanded air

• Compressed air

• Electricity

A 3/2 valve has

• 1.5 ports

• 3 ports and 2 directions

• 3 directions and 2 ports

• 5 ports and 2 directions

A double acting cylinder has

• has only one port

• has a return spring

• has no return spring

• has two return springs

This Schematic diagram is used to show ----------------valve

• Shuttle

• Dual

• And gate

The schematic diagram represents

• a time delay valve

• a shuttle valve

• a dual-pressure valve

• an “h” valve

What is name of this valve

• 5/2 way double solenoid valve

• 5/2 way single air pilot

• 3/2 way single pilot

• 3/2 way spring return

A double acting cylinder has

• has only one port

• has a return spring

• has no return spring

• has two return springs

A pneumatic valve is defined as a “5/3-valve”. What do the numbers 5/3 mean in this definition?

• The valve has a port for the exhaust.

• The valve has 5 switching positions and 3 ports.

• The valve has a neutral position and 4 other switching positions.

• The valve has 5 ports and 3 switching positions.

• The valve has 5 ports for work conductions and a neutral position.
