[ What is claimed:] [1.] A fluid displacement pump, comprising:(a) a housing, having a top wall, bottom wall, and side wall, the top wall, bottom wall and side wall each having an inner surface, the top wall, bottom wall, and side wall enclosing an interior therebetween,(b) means in the inner surfac
[ What is claimed:] [1.] A fluid displacement pump, comprising:(a) a housing, having a top wall, bottom wall, and side wall, the top wall, bottom wall and side wall each having an inner surface, the top wall, bottom wall, and side wall enclosing an interior therebetween,(b) means in the inner surface of the side wall for carrying a seal therein,(c) an elongated chamber of fixed length, formed by the inner surface of the top wall, inner surface of the side wall, and the seal, having an elongated piston reciprocally mounted therein, the piston sliding through the seal, the length of the piston being approximately the same as the length of the chamber,(d) means for accurately positioning the piston within the chamber so as to measure a fluid displacement,(e) a single port for alternately aspirating and dispensing fluid from the chamber, the port being located at the highest point of the chamber, thereby optimizing removal of air from the chamber; and(f) valve means for controlling the pump to allow the port to alternately aspirate and dispense fluid.
