Abstract

In some embodiments, a housing can define a reservoir. A lower cap can be coupled to the housing and define an outlet, and an upper cap can be coupled to the housing and can define an inlet. The upper cap can include an extending portion extending laterally a distance beyond an outermost extending portion of the lower cap relative to a central axis of the housing such that, when the lower cap and the extending portion of the upper cap contact a horizontal surface, the central axis of the housing is transverse to the surface and a sealing member is configured to sealingly engage a sealing surface of a valve seat prior to a liquid fluid level within a reservoir decreasing below a minimum threshold fluid level.
