Abstract: A ratchet clip for lockably and releasably closing a cover onto a base of a air filter housing is disclosed. The ratchet clip includes an elongated retention member secured at one portion of the housing and having a plurality of teeth forming a series of pockets and ridges. A rocker member is pivotally secured to a different housing portion and is aligned to lockably engage the retention member. A latching member on the rocker member is sized, configured and positioned to lockably engage into the pockets thereby inhibiting movement of the latching member in an opening direction relative to the retention member. A spring biases the rocker member to lockably and releasably engage the retention member thereby preventing movement in an opening direction of the rocker member relative to the retention member. The teeth have surfaces configured to permit the latching member to slide over the teeth in a closing direction relative to the retention member, even while the spring biases.

Abstract: An air cleaner for a motor vehicle includes a housing having an air inlet opening, an air outlet opening, a secondary air inlet opening and at least one peripheral wall defining a chamber therein. An air filter element is provided and received into the chamber and positioned to separate the air inlet opening from the air outlet opening. A vacuum actuated valve is provided in the secondary air inlet opening of the housing and is in communication with a secondary air portion of a dirty face of the filter element. The valve configured and adapted to automatically change from a closed to an open state when a vacuum in the housing increases to a predetermined vacuum value and then to close when the vacuum decreases below the predetermined value, thereby permitting the vehicle engine to continue to operate even though airflow in the primary air intake may be obstructed.
