Abstract
A vented pump includes a pump housing with a fluid retention cavity, a fluid inlet, and at least one vent opening therethrough. A pump dome is secured to the pump housing to form a dome cavity. Movement of the pump dome allows material from the fluid retention cavity to enter the dome cavity through the fluid inlet, and selectively allows ambient air to enter the fluid retention cavity through the at least one vent opening.
