Abstract
According to various aspects, exemplary embodiments are provided of valve apparatus and combination filter valve assemblies. One exemplary embodiment provides a combination filter valve apparatus suitable for filtering objectionable particulate matter from a fluid and for selectively occluding a fluid flow opening. In this exemplary embodiment, the apparatus generally includes an outer member, a sealing member, and filtration media disposed generally between the outer member and the sealing member. The filtration media may be configured to generally support the sealing member for resilient movement relative to a fluid flow opening between open and closed positions. In the open position, the sealing member may be spaced apart from the fluid flow opening. In the closed position, the sealing member may be in sealing engagement with and substantially blocking the fluid flow opening, thereby inhibiting the ingress of fluid into or egress of fluid out of the fluid flow opening.
