Abstract
Audible features are provided for a fluid filter assembly and a filter cartridge for use with a fluid filter assembly. The audible features generate sound when the filter cartridge is installed in the filter system so as to provide a signal indicating proper installation. Sound can also be created when the filter cartridge is removed. The filter system can also be provided with features for reducing clogging of the fluid path leading to the filter element.

A fluid filter assembly, comprising:
- a filter manifold comprising
- a filter manifold body;
- a fluid inlet and a fluid outlet adapted for coupling the filter manifold to a fluid supply system;
- a fluid return port in fluid connection with the fluid outlet;
- a plurality of teeth positioned proximate to the fluid return port;
- a fluid delivery port positioned proximate to the fluid return port, the fluid delivery port in fluid connection with the fluid inlet;
- a filter cartridge removably attached to the filter manifold, the filter cartridge comprising
- a filter housing;
- a filter element received into the filter housing;
- a filter outlet for a flow of fluid from the filter element out of the filter housing and into the fluid return port;
- a filter inlet positioned proximate to the filter outlet and in fluid connection with the fluid delivery port of the filter manifold;
- and
- at least one actuator positioned adjacent to the filter outlet and extending into contact with at least one of the plurality of teeth during installation of the filter cartridge onto the filter manifold, the actuator configured for providing an audible signal as the filter cartridge is installed.
A filter cartridge for a filter system, the filter cartridge comprising:
- a filter element;
- a filter housing defining a chamber into which the filter element is received, the filter housing having a filter outlet and a filter inlet in fluid communication with the chamber and configured so that fluid may pass through the filter element;
- and
- at least one actuator positioned adjacent to the filter outlet, the actuator extending longitudinally away from the filter element and configured to provide an audible signal during installation of the filter cartridge into the filter system.
