anybody know what this is?

[bseant]

this is on the intake side of my 1957 ir 242. im assuming its a silencer of somesort maybe? cant find any info on it, it has a spring loaded something on the inside and a gasket on top but i have no idea how to get a new parts since i have no idea what its called or what it is for that matter. Any info on what it is and how it works would be great.

could this be it

 

[bseant]

no i dont think so. that part has a crankshaft and moving piston it looks like. my part is more just like a flapper deal. LOL

It appears to be a one-way valve. Does the compressor have an intake valve on the cylinder that this attaches to?

 

[bseant]

Don't think i understand what you mean. It attaches to the low press side of the compressor as shown in pic 2 on the low press head it just goes up and into the valve body. i have just the down spout thing connected to the intake right now and it ***** pretty good since i rebuilt the compressor. on the newer 242's there is only a intake filter silencer and that's it. I kinda just wanted to know what this is and is any better or if i should just buy a solberg type intake filter/silencer.

Could it be an unloader valve?

on the intake side? there would be an unloader? I'll take better pics of the working guts of the thing and see if that helps.

Pump may not have any reed or poppet valves inside it, this may be a sophisticated engineer's ********* of a replacement for a simple reed valve. Don't know, just a wild guess.

an engineer definitely had a ahhhaa moment when he came up with this creation. lol. There are reed valves in the head all of which i replaced and also honed out the cylinder walls and put new rings on the pistons.

That is probably an unloader valve. When the compressor shuts off, it bleeds off the air pressure between the check valve and the compressor outlet port so the motor can start without a load.

Unloader valves would be on the exhaust side of the head.

I'm guessing that it is a regulator valve for an engine driven pump. The opening on the top plate is the sense line and it will move the spindle against the spring to either bleed off air from the sense line or block the intake of the pump to prevent air entering the pump to be compressed.

no neat sig line

heres some more pics. i do think it is an unloader valve but i don't know how to dial it in. Also i need a new rubber gasket deal that goes inside.

 

[bseant]

quick bump

 

[larry_g]

I'm sticking with my guess above. Can you determine the flow path through the valve in the two different states?

I cannot determine the flow air inside the thing. It's not for a engine driven pump as everything i have is how it came in 1957, motor, compressor and tank. i looked up ingersoll intake unloader valve on ebay and found some things that resemble what this thing is but mine looks like a tank compared to the ones their selling now for 400 bucks. thanks for any help, i'm hoping the service guy will call me back sooner or later.
