Valve to fill additional compressed air tank
Bob Engelhardt fired this volley in
:
It's a pressure relief valve. With an exit port, not just venting to
air. The tricky part is finding one with an adjustable differential, so
that it could be made to stay open until 90 psi. Bob
That doesn't solve the filling part, only the 'feeding' part.
A one-direction flow control valve will do both.
