Abstract:
A filter in some embodiments of the invention includes: a housing defining an interior chamber substantially sealed from outside of the housing; a valve located in the chamber biased to a first position where the valve maintains a seal between the interior chamber and outside of the housing; and an anchor fixed to the housing defining a surface for a spring to urge against and bias the valve to the first position and be compressed against when a receiver enters into the housing a moves the valve to a second position, the anchor defining, at least in part, flow paths wherein a pressurized fluid within the housing can communicate with an interior of the receiver to equalize a pressure within the chamber and the interior of the receiver; and a nipple attached to the housing having an interior passageway configured to permit the receiver to pass through in a substantially sealed manner. A method of attaching a filter to a filter receiver is also provided.
