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 18):
A breast pump assembly comprising:\n a housing assembly including a piston housing and a drive housing, the piston housing having a vent passage in direct communication with atmospheric pressure and a closure movably connected to the piston housing that is configured to selectively seal the vent passage; a piston assembly including a vent piston and a drive piston, the vent piston configured to actuate the closure between a vent orientation and a vacuum orientation; 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, wherein the vent orientation is defined when the vent piston actuates the closure to open the vent passage so that the pressure chamber is in direct communication with atmospheric pressure and the vacuum orientation is defined when the vent piston is disengaged from the closure, and wherein the diaphragm is disposed in the vent orientation between 15% and 60% of each cycle of the piston assembly.
