[ I claim:] [1.]1. A vacuum regulator for a breast pump, comprising:a nub having at least one port, said nub adapted to be in communication with a volume of said breast pump within which a negative pressure is periodically generated; anda rotary member having an internal groove, said rotary member being rotatably received over said nub, whereby said internal groove of said rotary member is open to atmosphere and is selectively positionable over said at least one port of said nub to adjust vacuum pressure by allowing air to pass to said volume when over said port and not to pass when not over said port.
