Filter housing
View Patent ↗A filter housing having radial sealing means is disclosed herein. Push-button actuated clamps can be used to attach the head to the sump for easy opening and closing the filter housing when replacing the filter cartridge. The filter housing of the present invention provides simplified filter cartridge changes to minimize process downtime and without recourse to tools.
1. 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.
2. A filter housing claim 1 wherein said radial sealing means comprises an O-ring, a quad seal, or a gasket.
3. A filter housing of claim 1 further including a safety mechanism that is responsive to a pressure inside said filter housing.
4. A filter housing comprising:
a sump for enclosing a filter cartridge within said filter housing;
a head having an inlet and an outlet in fluid communication with the filter cartridge, said head removably attached to said sump;
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; and
a clamp actuator comprising a rotary cam in conjunction with a linear cam, said rotary cam comprising:
a slotted tab including:
a first slot slidably fitted to a center axial pin extending from a top surface of said head;
a second slot slidably fitted to a pin off-axis from said center axial pin, said second slot angled relative to said first slot, such that said rotary cam is engaged when said slotted tab is moved in a radial, linear direction;
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 said radial, linear direction.
