A versatile filter structure adaptable for use in differently ported configurations includes accommodation for variations of bypass and shutoff valving and for filter element replacement from either end or centrally of the structure. A head casting is secured to a tubular housing and either may be the mounting device for the filter. A funnel shaped diverter having an oblique edge is removably mounted in the head casting and provides separation between inlet and outlet portions of the filter structure by means of an eliptical o-ring seal at the edge which engages the interior of the head casting. The diverter provides a smooth transition for fluid flow to the interior of the filter, supports one end of the filter element in the tubular housing, optionally houses a shutoff valve operative automatically upon filter element removal, and further houses a bypass valve for safeguarding against filter element blockage. The remote end of the housing which also supports the filter element consists in the different configurations of a welded-closed or removable end assembly, with or without a port and shutoff valving. An indicator mounted on the head casting is in fluid communication with opposite sides of the o-ring seal to monitor inlet and outlet pressure differentials.

A tubular filter assembly having a mount for the filter element which positions the element both axially and radially and allows axial replacement thereof through a removable end wall of the filter housing. The inward end of the filter element is slidably supported on a fixed end wall boss. A bypass valve is retained in the mount in a compact arrangement with a portion of the valve within the filter element and removable therewith. In a preferred embodiment the bypass valve is a glass-filled nylon, reversible, snap-in poppet valve assembly which is usable in different filter configurations.

A telescoping steering column is provided of the type wherein a wedge plug and innermost shaft portion are axially wound relatively to each other by rotation of a threaded rotatable control rod to thereby lock and release the innermost shaft portion relative to another shaft portion. First and second stop means are provided to respectively stop the control rod and the one of the two elements (innermost shaft portion or wedge plug) that is not threaded to the threaded control rod against relative axial movement in our direction and in the opposite direction. The first and second stop means allow a limited axial lost motion between the rotatable control rod and the said one element when the direction of the rotatable control rod is reversed so as to axially disengage one of the stop means and move the rod axially toward the other by the stop means.
