Tony Deye: POSITIVE
DISPLACEMENT ROTARY COMPRESSOR AND EXPANDER
Inventor: Tony Deye (RPC engines, Linton, Cambridge)
The problem:
The conventional piston and crank arrangement for
positive displacement compression and expsansion is unbalanced and due to its
geometry and mechanical features is less efficient than it could be.
The solution:
Three pockets and two lobes of the two rotors
on parallel shafts rotating leave a space between them which reduces
to nothing within a third of the turn of the shafts. If gas is allowed into the
space when it is at its largest, it will leave the space compressed just before
it is closed. The compression ratio
depends on the quantity of gas admitted, which is governed by a wedge shaped
slider control valve. Conversely, if the gas is introduced under high pressure
just after the gap opens between the lobe and the pocket,
it expands and turns the shafts which are connected by gear-wheels. Combining
the two functions by placing a fuel combustion chamber between the outlet of
the compressor and the inlet of the expander, we have a purely rotary and positive displacement engine.
Present status:
Well protected by numerous patents and it is
being developed in the inventor’s laboratory, where visitors are welcome. The application of the compressor to diesel
engines currently in use reduces their fuel consumption significantly.
