Hi.I need to unseize something.
I like that you use the word seize. As compared to the USA term frozen which I detest.

Hi.I need to unseize something.
Hi.
Not my money but................Just purchased what is probably the highest $$$ per Kg tool that I own
I always unplug my compressor when I have finished with it because it has a small air leak somewhere and will eventually start up again.whilst on compressors... I've one that turns itself back on from time to time, yep, the red button has been pushed to turn it off in the first place. First time was of course when I was just nodding off to sleep, all tucked in, thump-thump-thump..... bugger....

I'd reckon that my switch has got to be at least 15yrs old - but there are similar here that are much older. Particularly one on the unit I made up when I was but a lad, but that was an ancient fridge compressor dating back to the 40's at least !!The cheap chinesium switch lasted almost 20 years (of home use), which I think is a good run
This is the style of pressure switch that Bob has on his compressors.do compressors have an on/off switch?? I'll have to search mine someday and see. I just use the much more accessible switch .... on the wall... where its plugged in
Switching on/off at the wall plug only works if your compressor tank leaks....do compressors have an on/off switch?? I'll have to search mine someday and see. I just use the much more accessible switch .... on the wall... where its plugged in
Not sure about all compressors but on mine when the tank comes to the cut off pressure of the pressure switch, the motor is turned off and the pressure switch drains the air between the compressor and the check valve at the entry to the tank.Switching on/off at the wall plug only works if your compressor tank leaks....
If it didn't leak you have a higher chance of the motor stalling and you'll likely hear the wall switch buzzing as it draws maximum amps when you turn it on.
When you push the red knob down it forces the pressure switch contacts to separate and a lever then actuates the pressure switch relief valve to relieve the pressure that was trapped between the pump and check valve so the motor won't stall when you turn it back on.
How is that dump valve operated Roger?Both my compressors have a dump valve that automatically releases the trapped air as soon as the motor stops. It is physically separate from the pressure switch.

OK, interesting, never taken that much notice of what's going on.... The unit that starts up on it's own always has a hard time staring up from cold - but runs OK on it's cycle restart. Might be a guide there....Compressors are designed to be started up under no load or unloaded conditions, otherwise you end up with the stalling that you mention.
The fridge compressors make an ideal small compressor. I have one here that I made up about 30 years ago to pump up bike tyres etc. Its small and light enough to carry aroundOK, interesting, never taken that much notice of what's going on....

The oldie with the ex-fridge compressor doesn't have any fancy stuff in the switch, bare bones simple, but you won't stall it - only a quarter-horse motor but it's got repulsion start, rip yer bloody arms off.....

Looks like yours is from a commercial fridge. Well built and would last another hundred years.
