Abstract
A diaphragm pump can include an inlet, an outlet, and a pump chamber positioned in a fluid path between the inlet and outlet. The assembly can include a diaphragm and a movable piston. Movement of the piston toward the pump chamber can force a portion of the diaphragm to move from its rest position to a position further within the pump chamber and to increase pressure in the pump chamber. Movement of the piston away from the pump chamber can force a portion of the diaphragm to move from its rest position to a position away from the pump chamber and to reduce pressure in the pump chamber. The assembly can also include a first and second check valve. In the closed position, the second check valve can be unsealed to provide an escape path for gas. In the closed position, the first check valve can be sealed.
