Pistonless Pumps in Automobiles

All the new high effeciency air conditioning compressor units are scroll pumps.

Rockets use turbopumps for fuel and oxidizer feeds. Essentially they are turbochargers with one turbine driving the other. generally they use the phase change of the liquid that is circulated around and through the bell nozzle to a gas to drive the turbine. Piston pumps have NEVER been used on rockets. not even the Germans used piston pumps in the V2.

Wait, I just had an idea. Suppose you took the principles used in the centrifugal pump, and after the air was compressed you injected some kind of fuel into it and ignited it. The exhaust air rushing out could be harnessed to draw additional air into it and compress it all over again. Does anyone think this idea could get off the ground?

Will this be like the 'balloon/bubble"?

nice of you to thrust that idea on here.

hhaahhaaha

I think this guy may be working on that idea....

Don't tell me I have waisted my money on patenting my work.

you should probably invest your money in hiring a malpractice lawyer to sue your patent attorney...

As good a waste, if not perfect.

Hello bob c:

Your idea is not unsound, DaS Energy did. The worlds first pistonless engine utilises a hydro turbine in place of crankshaft, and liquid piston acting the same as a solid one and a single cylinder engine has but one valve which is a ball float.

The DaS Valve, is still listed CR4 I think and that was first used in power generation then taken further into the piston engine.

Engine makers fell over themselves knocking it back. While engine sellers told us if they put our engine on the shelf they can take every other one off. Good tactics I thought, you sell DaS we no longer supply you.

Cheers Peter

Hello bob c:

To possibly be of help. We first looked at the centrifical pump in our work.

The process works by having a length of pipe joinded to the pump inlet.

The pipe to pump inlet allows air to be drawn in with the water.

On the pipe before reaching the pump are two vertical cylinders the first is an air capture tank with ignition device.

The air fuel mix along with the water being drawn up the pipe escape rises into the first cylinder here it builds up pressure to the pre set ignition pressure.

Combustion drives the water into the pump reverting it from pump to turbine during the combustion phase.

The exhaust gas folllows into the pipe and is exhausted through the next vertical cylinder the DaS Valve.

At this point the pump converts back into a pump being rotated by the spin of the flywheel.

The draw action of the pump sets the combustion process in train again.

Back yard construction involves a solid centrifical pump, length of solid pipe, floating sphere, pressure switch, battery, coil and spark plug.

Shall redraw and post, long time ago now first did.

Cheers Peter.
