What is a hydraulic air pump?

[Lutherman]

This is in regards to the air car designs of Bill Truitt. I have been finding recurring mentions of "hydraulic air pumps" in the ever-expanding literature on self-fueling air cars, which has prompted me to go back again to Bill Truitt's design and question the one part of it I never could figure out.

Other inventors are found making big claims for this kind of air compressor whatever it is. One even states that when using hydraulic power to compress air, there is an inherent overunity situation. Anybody know why? Something about force multiplication or what?

My guess on Truitt's pumps is that they comprised a small hydraulic pump and an air piston in the same unit. The air piston would be reciprocated by hydraulic fluid on the non-air side instead of a piston rod. I can see a big advantage in doing this. Maybe even the machine could be started without an unloader, kind of important since Truitt's pumps--several pairs of them--were directly geared into the car's rear end by a power take off shaft, so they pumped air the whole time the car was moving. Without a clutch it would be hard to start the car because of the air pumps.

Maybe the hydraulic instead of mechanical action would allow the car to start easy without unloading first like most compressors would have to be done.

As for really exotic ideas, think about this. Any resistance on the part of the air being compressed is going to push back on the hydraulic fluid, whose pressure goes up drastically at the slightest push since it is incompressible. So wouldn't compressing air with hydraulics be like cutting daisies with a chainsaw? OK if there's a reason for it.

If anyone has real world knowledge of what a hydraulic air pump is and what they are used for, please clue me in. I haven't been able to find such a thing on the market. If they really do perform miracle stunts then no doubt they were taken off the market when someone figured that out.

Absolutely no idea. Could be simple misdirection; unfortunately there's miles of garbage to wade thru in researching free energy.

Good luck, I hope you find out

kunkel's pump

Did you ever study the pyramid pump?

In the 50's A hydraulic engineer looking at the side view of the chambers of the pyramid claimed it was a ram pump. His name is kunkel and has a patent (on my other computer) to prove that it works.
The patent office actually made a visit to his home for proof.

The only thing it needed according to Kunkel was a flame to pull the expanded water gas out of gas state and suck the piston up.

Kunkel says the pump uses the atmospheric pressure 2 times and water pressure 1 or 2 times as well in each cycle.

I believe this pump qualifies as a hydraulic/pneumatic device. It is totally free energy, after it is built, but Kunkel said it needed to be big enough to get the forces to start. He said a kitchen table sized replication would not work.

BTW, when the extreme vacuum of the gallery pulls the water molecules apart, they look a lot like HHO, and a spark is all that would be required to keep it going.

I have not studied the link posted below, but I think it is quoting Kunkel's work.

hydraulic air pumps

Ram pumps of all sizes have been made, that is like you say a kind of hydraulic pneumatic design but in reverse. The hydro power combined with air pressure is used only to pump water back uphill. The air pressure is thrown away.

Just imagine a normal piston compressor with the pushing done by hydraulic fluid on the back side of the piston, instead of a piston rod. I think the RAMifications are somewhat astounding.

Hi Luther,
I may be late, but if not, Google up "liquid ring vacuum pump".

With kind regards, Slavek.
