Response to Re: Wow---how many pumps did you

thing is a check valve.
And in fact, its round and slides up and down inside the valve.
Its held in place by the valve spring which keeps it shut over the little hole in the end of the valve to hold the air in it.
You overcome the springs pressure by pumping the forearm and the piston pushes the air in the little hole.
The other end of the valve spring holds the exhaust valve shut until the hammer hits it and opens the valve to release the air into the exhaust port and out the barrel.
Hope this helps.

P.S. If it worked before, hopefully cleaning it out and putting it back
together will fix the problem without having to buy a new one.
Besides, the brass valves are the good ones.
The new valves are all aluminum.
