Abstract
In the illustrative embodiments of the invention described, a pressurized fluid device of the cylinder and piston rod type includes, at one end thereof, an elastomeric closure member which is movable, under the force of the fluid to be introduced into the device, away from a sealing position with respect to the cylinder, and piston rod to a position in which the fluid is admitted into the cylinder for purposes of charging the same. Upon completion of the charging, or fluid-filling, step the closure member is returned to the sealing position either by movement of the piston rod alone or in conjunction with the action of the fluid pressure within the cylinder.
