Abstract
An expansible bellows, includes a pair of end plates attached together and sealed around their peripheries such that their inner faces confront each other to define between them an expansible chamber for containing a fluid. One end plate is formed with an inlet port to the chamber; and the other end plate is formed with an outlet port from the chamber. The inner and outer faces of both end plates are formed with recesses which permit the center portions of the end plates to flex outwardly, and thereby to expand the chamber, when pressurized fluid is inletted into the chamber via the inlet port and blocked from flowing out of the chamber through the outlet port. Also described is a pulsator including such a bellows serving as the expansible chamber of the pulsator.
