Patent ID: 7651070

Claim:
A combination manifold and valve system for removable attachment to a filter module, the system comprising: a central structural element including an inflow opening, an outflow opening and a substantially circular inner cavity; a rotatable structural element positioned within the inner cavity of the central structural element and including a first opening, a second opening and a cantered element; and a securing member slideably attached to the central structural element and interfacing with the cantered element of the rotatable structural element; wherein the rotatable structural element is rotatable, with respect to the central structural element and the securing member, from a first position to a second position; at the first position, the first opening of the rotatable structural element is aligned with the inflow opening of the central structural element, the second opening of the rotatable structural element is aligned with the outflow opening of the central structural element, and the cantered element interfaces with the securing member so as to hold the securing member in a securing position at which the securing member secures the filter in operational engagement with the central structural element of the system; and at the second position, the first opening of the rotatable structural element is completely offset from the inflow opening and the second opening of the rotatable structural element is completely offset from the outflow opening, so as to shut off the inlet and outlet openings, and the cantered element interfaces with the securing member thereby allowing the securing member to be released from the securing position so that the filter module can either be attached to or removed from the system.
