An improved breast pump comprised of a manifold having a cavity and plurality of openings. A horn is positioned in one of the openings for coupling the mother\s breast with the cavity. A first fixed cylinder is formed integrally with a second opening of the manifold with a second cylinder slidingly received over the first cylinder for effecting a pumping action therebetween to create a reduced pressure within the horn, cavity and cylinders. A third opening is for the coupling of a baby bottle therewith. A ball valve is located within the third opening whereby when the second cylinder is reciprocated with respect to the first cylinder and a vacuum created in the horn, cavity and cylinders, the ball valve will seal the third opening and the bottle from the cavity and suck milk from a mother\s breast located in association with the horn.

A breast pump for extracting milk from a mother\s breast comprising: a central manifold having a cavity and a plurality of openings; a horn for coupling a mother\s breast to be milked with the cavity of the manifold, the horn being symmetric about a first axis over the majority of its extent, the horn also having a projection rotatably positioned within one of the openings, the projection being symmetric about a second axis at an angle with respect to the first axis for varying the angular position of the horn with respect to the manifold for the convenience of the mother; a first fixed cylinder formed integrally with a second opening of the manifold; a second cylinder reciprocatingly received on the first cylinder for effecting a pumping action therebetween to create reduced pressure in the space within the horn, manifold and cylinders; a third opening within the manifold for coupling of the baby bottle therewith; and a ball valve located within the third opening whereby when the second cylinder is reciprocated with respect to the first cylinder and a vacuum created in the space within the horn, manifold and cylinders, the ball valve will seal the third opening and bottle from the space of reduced pressure and suck milk from a mother\s breast in association with the horn.
