Abstract
An oscillatory fluid pump is provided with a horizontally disposed cylindrical chamber disposed above and in communication with a rectilinear chamber along the entire length of both chambers. An inverted Y-shaped elastic member is secured at the lower ends of the downwardly angularly related legs to the bottom of the rectilinear chamber and the upstanding leg is secured to a cylindrical pumping member located in the cylindrical chamber. A cylindrical bore is eccentrically located along the length of the cylindrical pumping member of a drive shaft having an eccentric thereon extends through the bore and is supported at opposite ends by the housing. A bearing is located between the eccentric and the bore so that upon rotation of the shaft the eccentric will cause the cylindrical pumping member to move in a circular motion about the internal surface of the cylindrical chamber to pump fluid from an inlet in one side of the rectilinear chamber about the internal surface of the cylindrical chamber and outwardly through an outlet opening in the opposite side of the rectilinear chamber.
