Liquid filter apparatus

Claim 2

Filter apparatus for filtering water and particulate matter from a liquid, comprising, in combination: first filter means including a layer comprising a plurality of stratified discrete flat strips randomly oriented in planar layers, with the flat portion of adjacent strips generally parallel and disposed against each other, for filtering particulate matter from the liquid, second filter means including desiccant means for filtering water from the fluid; and housing means for the first and second filter means.

Claim 3

The apparatus of claim 1 in which the first filter means includes a first filter layer and a second filter layer, and the second filter means is disposed between the first and second filter layers of the first filter means.

Claim 4

The apparatus of claim 3 in which the first and second filter layers of the first filter means each comprises a plurality of layers of generally flat pieces of aluminum, each piece of which is randomly oriented and disposed against and in an overlying and underlying relationship with respect to adjacent pieces.

Claim 5

The apparatus of claim 3 in which the desiccant means comprises a layer of silica gel.

Claim 6

The apparatus of claim 4 in which the housing means includes a circumferentially extending rim and a flange extends outwardly from the rim.

Claim 7

The apparatus of claim 5 in which the first and second filter means are disposed concentrically with respect to each other.

Claim 8

The apparatus of claim 4 in which the housing means includes a cylindrical housing having a plurality of apertures communicating with the first filter layer of the first filter means for admitting a flow of liquid to the filter apparatus, and a conduit communicating with the second filter layer of the first filter means for providing a flow of fluid out of the filter apparatus.

Claim 9

Filter apparatus for filtering particulate matter and water from a liquid, comprising, in combination: cylinder housing means including means for admitting a flow of liquid into the cylinder housing means; first inner cylinder means including first filter means for filtering a portion of the flow of liquid; second inner cylinder means including second filter means for filtering another portion of the flow of liquid, said second inner cylinder means including an impervious housing having a plurality of apertures communicating with a portion of the second filter means disposed within said housing, and said second filter means including a filter layer comprising a plurality of layers of discrete generally flat stratified elements oriented randomly with adjacent elements disposed against each other, and a layer of desiccant means, through which layers the other portion of the liquid sequentially flows; first conduit means connected to the cylinder housing means and to the first inner cylinder means for providing a flow of liquid out of the inner cylinder means; and second conduit means connected to and extending between the first conduit means and the second inner cylinder means for providing a flow of liquid from the second inner cylinder means.

Claim 10

Filter apparatus for filtering particulate matter and water from a liquid, comprising, in combination: cylinder housing means including means for admitting a flow of liquid into the cylinder housing means; first inner cylinder means including first filter means for filtering a portion of the flow of liquid; second inner cylinder means including second filter means for filtering another portion of the flow of liquid, said second inner cylinder means including an impervious housing having a plurality of apertures communicating with a portion of the second filter means disposed within said housing, and said second filter means including a filter layer comprising a plurality of layers of discrete generally flat stratified elements oriented randomly with adjacent elements disposed against each other, and a layer of desiccant means, through which layers the other portion of the liquid sequentially flows; first conduit means connected to the cylinder housing means and to the first inner cylinder means for providing a flow of liquid out of the inner cylinder means; and second conduit means connected to and extending between the first conduit means and the second inner cylinder means for providing a flow of liquid from the second inner cylinder means.

Claim 11

The apparatus of claim 8 in which the second filter means includes a first and a second filter layer, each of which comprises a plurality of layers of discrete, generally flat elements oriented randomly with adjacent elements disposed against each other, and the layer of desiccant means is disposed between the first and second filter layers.

Claim 12

The apparatus of claim 9 in which the generally flat elements comprise aluminum strips and the desiccant means comprises silica gel.

Claim 13

The apparatus of claim 8 in which the first conduit means includes a flared portion disposed within the first inner cylinder means.

Claim 14

The apparatus of claim 11 in which the second conduit means is connected to the second inner cylinder means and extends to and is connected to the first conduit means adjacent the flared portion.
