Abstract: A system of where internal friction otherwise known to be back pressure or resistance is eliminated and iterations of power transfers allows for a greater use of the effort put into the use of the device embodied within the 2 powered system, as presented here as to teach others how we, as in the use of shared and sustained power, may be able to reduce the consumption of power and where certain artifacts are taken to power stages within a hose. To aid in lessening the power needed when a material is compressed into a hose forcing a pump implemented in the duty range to produce such pressure is unduly burdened. To achieve equilibrium within the material delivery system by inducing movement and in doing so making the jerking action of energy transfer across unequal pressures to be relieved.

Abstract: A bellows is configured for use on a valve. These configurations may include a corrugated section that is hollow to receive a valve stem therethrough.
