ABSTRACT:
A valve system for a fluid pumping assembly including a valve plate having at least one intake port extending therethrough and at least one discharge port also extending therethrough. The discharge port includes a central axis extending through the discharge port and orthoginal to the valve plate. The intake port is a slot having a width less than its length and subscribing an arc radially spaced from the central axis of the discharge port. A suction reed valve has a valve member that is defined at its distal edge by an arcuate slot in the valve wherein the slot is disposed arcuately and radially spaced from a discharge aperture in the valve member and terminates at either end in inwardly extending lobe portions that define a neck portion in the valve member having an axis about which the valve member moves between open and closed positions.
