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.
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.
