What is the purpose of using two cylinders in a Moriya Stirling engine fan?

In summary, the Moriya design uses two different cylinders that are not connected. One for the power piston and one for the displacer piston.

The design in that link *does* have two cylinders -- one for the power piston and one for the displacer piston.

But in the moriya design, there are two different cylinders that are not connected. (power and displacer are separated.

Here the two "cylinders" are connected in the link.

In the Moriya design there is a drilled passage in the base, that connects the two cylinders. You can't see this from the outside. The outer end of the passage (where the drill went in) is closed off with a threaded plug. Depending on how the engine is mounted, the legs may cover up this plug so you would not see it.

I built one of these as a school project (35 years ago!) following the plans in Live Steam magazine (December 1974 thru February 1975). The engine still runs fine.

Good luck, it is a fun project.

I see! thanks!

What is a Moriya Stirling Engine Fan?

A Moriya Stirling Engine Fan is a type of fan that uses a Stirling engine to convert thermal energy into mechanical energy, which then powers the fan blades to create air flow. It is named after its inventor, Dr. Moriya, and is known for its quiet operation and energy efficiency.

How does a Moriya Stirling Engine Fan work?

The Moriya Stirling Engine Fan works by using the principles of thermodynamics to convert heat energy into mechanical energy. It has two cylinders, one hot and one cold, with a gas-filled working fluid that expands and contracts as the temperature changes. This movement drives a piston, which in turn powers the fan blades.

What are the benefits of a Moriya Stirling Engine Fan?

One of the main benefits of a Moriya Stirling Engine Fan is its energy efficiency. It does not require electricity to function, making it a more sustainable and cost-effective option. It also operates quietly, making it ideal for use in quiet environments such as bedrooms or offices.

Is a Moriya Stirling Engine Fan better than a traditional electric fan?

This depends on personal preference and specific needs. A Moriya Stirling Engine Fan may be a better option for those looking for a more sustainable and energy-efficient fan, while a traditional electric fan may be more convenient for those with easy access to electricity.

Can a Moriya Stirling Engine Fan be used in all climates?

Yes, a Moriya Stirling Engine Fan can be used in all climates as it operates based on temperature differences, not just hot or cold weather. However, it may not be as effective in extreme temperatures, such as very high or low temperatures, as these can affect the performance of the Stirling engine.
