Abstract
A collapsible pump chamber includes several functional elements of a pump device. For example, the collapsible pump chamber may be a bellows which includes a functional element of an outlet valve, a functional element of a biasing feature, and a functional element of a spin chamber. Consequently, a functional element of all of the downstream functions are incorporated into the bellows. This can significantly reduce costs; due to reduced tooling, and assembly, for example. Since it can be desirable to separate these functions (e.g., to achieve more consistent spray quality), a process is described for severing functions from the multiple function collapsible pump chamber during the assembly of the pump device.
