Classification: CPC F | IPC F

Claim 8:
9. An assembly for a diaphragm pump, comprising:
a body defining a plurality of diaphragm chambers spaced apart about a body axis, wherein each diaphragm chamber defines:
a membrane opening,
an inlet chamber in fluid communication with each diaphragm chamber, and
an outlet chamber in fluid communication with each diaphragm chamber;

a plurality of flexible membranes that each comprise an outer edge, wherein the body is configured to clamp the outer edge of each membrane along a corresponding membrane opening to seal a corresponding one of the diaphragm chambers; and
a mounting ring configured to wobble about the body axis and defining a mounting ring axis;
wherein the membranes are configured to deflect substantially in parallel to the body axis to suction fluid into each diaphragm chamber from the inlet chamber and discharge fluid from each diaphragm chamber into the outlet chamber;
wherein each membrane comprises:
a coupling section coupled to the mounting ring and arranged along a diaphragm axis, and
a deflection section arranged radially outwardly from the coupling section and configured to deflect in response to movement of a pump drive; and

wherein the mounting ring axis and the body axis intersect at a location that is substantially co-planar with an interface between a valve plate and a carrier plate.
