ABSTRACT:
A lever actuated valve stem for control of liquid flow through a filtering device. The device is connectable to a source of impure liquids and includes a filter disposed between the inlet and the outlet of the device for the removal of the impurities. The valve stem is operable to direct fluid flow through the filter or to bypass the filter. The valve includes a lever slidably connected to a valve stem by means of a pin fixably attached to the lever and extending through a slot of the stem. The slot is arranged relative to the longitudinal axis of the stem to lock the pin and lever in either the filtering position or the bypass position.
