  • Publication number: 20070163947
    Abstract: A filter assembly includes housing enclosing a replaceable filter element. A support core is provided in the housing, and includes an extension and locking assembly. The element includes a ring of filtration media with a pair of end caps. The first end cap includes a central opening to receive the support core. The extension and locking assembly prevents the cover of the housing from being attached to the housing body without a proper filter element installed. The extension and locking assembly includes a bypass member and a locking member, which are in locking engagement when an element is absent in the housing. The second end cap includes internal protrusions which engage the locking member when the filter element is installed to disengage the bypass member from the support core, and allow the element to be inserted and the cover to be installed.

  • Publication number: 20050224031
    Abstract: The present invention provides a wax motor actuated valve assembly for controlling the flow of coolant to a heater core or cores until the coolant reaches a predetermined operating temperature. The wax motor actuated valve has particular application to vehicle cabin heating systems comprising front and rear heat exchangers (cores) over which air can pass for heating front and rear portions of the cabin, respectively. Initially, flow to the rear heat exchanger is shut off until the temperature of the coolant reaches a predetermined elevated temperature, whereby initial coolant flow is directed to the front heat exchanger for more rapid heating of the forward portion of the vehicle cabin. After the predetermined elevated temperature has been reached, the wax motor valve assembly is actuated to supply coolant to the rear heat exchanger for heating the rear portion of the vehicle cabin.
