FILTER WITH NON-HORIZONTAL CAVITY
Filters that include non-horizontal filter cavities, such as cavities that are vertically, diagonally, or otherwise non-horizontally with respect to a filter block.
1 . A filter block comprising:
a first exterior surface and a second exterior surface;
a first inlet port in the first exterior surface;
a first outlet port in the second exterior surface;
a first filter cavity extending between the first inlet port and the first outlet port, wherein the first filter cavity is oriented in a generally non-horizontal direction when in use; and
a first filter element within the first filter cavity.
2 . The filter block of claim 1 , further comprising a second inlet port in the first exterior surface, a second outlet port in the second exterior surface, and a second filter cavity extending between the second inlet port and the second outlet port, wherein the second filter cavity is oriented in a generally non-horizontal direction when in use.
3 . The filter block of claim 2 , further comprising a second filter element within the second filter cavity.
4 . The filter block of claim 1 , wherein the first filter cavity is oriented in a generally vertical direction when in use.
5 . The filter block of claim 1 , wherein the first filter is characterized by a height of between 0.5 inches and 2 inches.
6 . The filter block of claim 1 , wherein the first filter element comprises a metallic material.
7 . The filter block of claim 6 , further comprising a gasket that forms a seal between the first filter element and the first filter cavity.
8 . The filter block of claim 7 , wherein the gasket comprises a metallic material.
9 . The filter block of claim 8 , wherein the filter element is a filter tube.
10 . The filter block of claim 1 , wherein the filter element is in the shape of a cup.
11 . The filter block of claim 1 , wherein the first filter element is oriented in a generally horizontal direction when in use.
12 . The filter block of claim 1 , wherein the first filter cavity is oriented in a vertical direction when in use.
13 . The filter block of claim 1 , wherein the first filter cavity is oriented in a diagonal direction when in use.
14 . A filter block comprising:
an inlet port;
an outlet port connected to the inlet port by a flow passage;
a filter cavity within a flow passage between the inlet port and outlet port, wherein the filter cavity is oriented in a vertical direction when in use; and
a filter element within the filter cavity.
15 . A filter block comprising:
an inlet port;
an outlet port connected to the inlet port by a flow passage;
a filter cavity within a flow passage between the inlet port and outlet port, wherein the filter cavity is oriented in a diagonal direction when in use; and
a filter element within the filter cavity.
