Abstract
Abstract A method of and apparatus for displacing fluids in which a housing is provided which has an end wall and an opening opposite the end wall. A blade is positioned in the housing and rectilinear motion is imparted to the blade so that one end of the blade is moved while the other end dwells so that fluid is drawn in to one side of the blade and expelled by the reducing volume on the other side of the blade.

Dependent Claim
38 words
An apparatus as claimed in either claim 2 or 3, wherein means are provided at an attached end of said plate to sealingly associate said plate with said end wall when said attached end contacts said end wall.
Claim 14
Dependent Claim
44 words
Apparatus for displacing fluids as claimed in claim 1 wherein said flow dividing means comprises at least one valve, said at least one valve substantially closing the pathway of one stream when fluid is being admitted or displaced by virtue of the other stream.

Apparatus for displacing fluids as claimed in claim 13 wherein said at least one valve is positioned at the outlet end of said housing.
Claim 16
Dependent Claim
36 words
Apparatus for displacing fluids as claimed in claim 1, wherein said timing means causes each end of said plate to pause after movement of that end while movement of the other end of the plate occurs.

Claim 19
Independent Claim
415 words
A method of displacing fluid, said method comprising the steps of imparting rectilinear motion to a plate having a first end and a second end positioned in a housing which housing includes a first wall and an opposite second wall and an end wall having at least one aperture in it, said housing having at least one opening opposite said end wall, said motion being effected by at least two moving means, said moving means being a first moving means and a second moving means disposed one at each end of said plate, said method effecting a cycle of movement by including the steps of: sealing said first end of said plate against said first wall of said housing and sealing said second end of said plate against said opposite second wall; actuating said first moving means to move said first end of said plate adjacent said at least one opening from the sealing position against said first wall of said housing to a position against said opposite second wall of said housing while said second end of said plate is held in sealing relationship with said opposite second wall by said second moving means; sealing said first end of said plate against said opposite second wall; actuating said second moving means to move said second end of said plate across said end wall from said sealing relationship with said second wall to a position against said first wall while said first end is held in sealing relationship with said second wall; sealing said second end of said plate against said first wall; actuating said first moving means to move said first end of said plate from said sealing relationship with said second wall to a position against said first wall while said second end of said plate is held in a sealing relationship with said first wall; sealing said first end of said plate against said first wall; and actuating said second moving means to move said second end of said plate from sealing relationship with said first wall to a position against said second wall; sealing said second end of said plate against said second wall while said first end is held by said first moving means in sealing relationship with said first wall, said cycle being effected in forward or reverse order so that fluid is displaced from said housing in a desired direction, each movement of said plate being such that fluid is displaced from said housing in a desired direction.
