Pressure cleaner running off eutectic fridge compressor

[Guidogidday]

Hi,
Wondering whether anyone knows whether it's possible to turn an idle eutectic fridge compressor into a pressure cleaner?

Usually no, if what you mean is a pressure washer for water. A typical refrigeration compressor allows refrigerant to circulate in the crankcase.

Impossible (unless you have NASAs budget)

air and refrigeration compressors pump gas not liquid.I think pressure washing pumps are gear pumps

Not true, the vast majority of pressure washer pumps are in fact piston pumps.

No offence meant.....I just wanted to be clear that a gear pump isn't what 99% of pressure washers, or small hydraulic systems for that matter are made of.

Did a little reading.. seems they are "plunger" pumps rather then piston. I suppose the difference is that they move liquid in a way that would destroy compressor type pistons.

that's correct, a piston/plunger for moving a liquid doesn't' use a timed valve train like an engine, just a check valve.
Either way, a refrigeration compressor has the pumped medium present in the crankcase.....water will kill it.

Thanks everyone! Most educational. Seems like a larger generator to drive a pressure cleaner or some elbow grease will have to be the go.

Still must exist a bypass valve on a water pressure pump. One I took apart had 3 plungers in a triangle arrangement and I think was driven by a waffle plate.
It cracked, it was a Karcher. When it cracked water leaked everywhere.
Out of 3 Karchers I know about, all three of them failed in their pumps.

Otherwise, I liked it a lot being electric.
