Abstract:
An electrical breast pump may include a permanently unobstructed continuous passageway across the diaphragm and a rolling diaphragm that is movable between a vent orientation and a vacuum orientation, or a vent piston configured to actuate a closure between a vent orientation and a vacuum orientation so that a pressure chamber is selectively in direct communication with atmospheric pressure.

Claim (Index 19):
A breast pump assembly comprising:\n a housing assembly including a piston housing and a drive housing; a piston assembly disposed within the housing assembly, the piston assembly including a vent piston and a drive piston; a rolling diaphragm including an outer end, an outer margin disposed adjacent the outer end, where both of the outer end and outer margin are sealingly captured between the piston housing and the drive housing, an inner end, and an inner margin disposed adjacent the inner end, where the inner margin is sealingly captured between the vent piston and the drive piston to cooperatively define a pressure chamber between the diaphragm, piston housing and vent piston; and a vent passage in communication with the pressure chamber and atmospheric pressure, wherein the vent passage is selectively sealed to define a vacuum orientation and a vent orientation.
