Abstract

A POSITIVE DISPLACEMENT PUMP COMPRISE A VARIABLE VOLUME PUMP CHAMBER (16-1) AND A DRIVE MECHANISM (26-1) HAVING A DISPLACEMENT MEMBER (25-1) FOR REDUCING THE VOLUME OF THE PUMP CHAMBER (16-1). FLUID ENTERS THE PUMP CHAMBER (16-1) FROM A SUPPLY CHAMBER (15-1) LOCATED ADJACENT TO AND SURROUNDING THE LATERAL OUTER BOUNDARY OF THE PUMP CHAMBER (15-1) THROUGH A VALVE-CONTROLLED INLET PASSAGE (17-1) THAT OPENS TO THE PUMP CHAMBER (16-1) AT AN ELONGATED GAP-LIKE INLET OPENING. THE INLET PASSAGE PERMITS FLUID TO FLOW FROM THE SUPPLY CHAMBER (15-1) INTO THE PUMP CHAMBER (16-1) WITH SUBSTANTIALLY NO PRESSURE DROP. (FIG. 1)
