First Claim
Patent Images
1. An extractor, comprising:
- an extraction vessel having an internal surface which defines an extraction chamber which communicates between open extraction vessel first and second ends;
a first piston adapted to sealably engage said internal surface of said extraction vessel first end;
a first piston retaining member;
a first piston retaining member guide including a first piston retaining member guide channel in which said first piston retaining member moves to engage said first piston sealably engaged with said internal surface of said extraction vessel first end;
a first pressure receiving plate adjacently abuttingly engaging a first side of said first piston retaining member guide; and
a first end plate adjacently abuttingly engaging a second side of said first piston retaining member guide, said first end plate having a first piston aperture through which said first piston moves to sealably engage said internal surface of said extraction vessel first end.

Abstract
Generally, an extraction system useful in separating an extract from a matrix using one or more extractants. Specifically, an extractor including one or more of: an extraction vessel having an extractor vessel internal surface which defines an extraction chamber which communicates between open extraction vessel first and second ends, a first piston configured to sealably engage the extractor vessel internal surface of the extraction vessel first end or a second piston adapted to sealably engage the extractor vessel internal surface of the extraction vessel second end.
