Patent ID: 7306111

Claim:
A filter housing comprising: a sump for enclosing a filter within said filter housing; a head removably attached to said sump, said head having an inlet and an outlet in fluid communication with the filter cartridge; a radial sealing means for providing a liquid-tight seal between said sump and said head; a pressure relief mechanism for depressurizing said sump prior to removing said sump from said head; at least two clamps under a tension load in peripheral arrangement for attaching said head and said sump, said at least two clamps having a planar portion thereof; and a clamp actuating mechanism comprising a radial linear cam in conjunction with a rotary cam, said rotary cam comprising: a slotted tab including: a center slot fitted to an axial pin extending from a top surface of said head, said center slot in a radial direction; and a second slot fitted to a second pin off-axis from said axial pin, said second slot angled relative to said center slot in a non-radial direction, such that upon radially linear movement of said slotted tab and said center slot relative to said axial pin, said second slot is moved while in slidable communication with said second pin, causing said rotary cam to rotate; a first linear track and a second linear track equidistant from said center slot and being parallel to one another; and tracking pins extending from said clamps top surface traveling within each of said linear tracks when said rotary cam is engaged when said linear cam is moved in a radially linear direction, wherein the radially linear motion of the linear cam is translated to rotational motion of the rotary cam to open said at least two clamps when said linear cam is moved along a plane.
