<p>An oil filter apparatus comprises a base portion (30) having an aperture (26), a drainage valve (18) positioned for movement between an opened position allowing oil to drain out of the base portion (30) through the aperture (26) and a closed position blocking drainage of oil out of the base portion (30) through an aperture (26), a filter module (14) positioned in the base portion (30) to filter oil, a valve actuator (24) coupled to the filter module, and an anti-rotation rib (72) positioned in the base portion (30) and a rib-receiving notch (74) formed in the filter module (14) to block rotation of the filter module (14) relative to the base portion (30) to guide the valve actuator (24) into communication with the drainage valve (18) to move the drainage valve (18) to the closed position when the filter module is installed in the base portion (30).</p> |
