The bellows are actuated by the pressure generated by the volatilization of a low-boiling liquid. Until recently they were still available new as manufactured by the original OEM via Bill Hirsch, but I believe now your recourse is to one of several rebuilders of them, or attempting it yourself. Lots of documentation available on the process.
