1. A compressor comprising:
a scroll including an end plate and a spiral wrap extending from the end plate, the end plate including a discharge passage; and
a discharge valve assembly mounted to the scroll and configured to control fluid flow through the discharge passage, the discharge valve assembly including a base and a valve member, wherein the base is fixed relative to the end plate and includes a discharge opening in communication with the discharge passage, wherein the valve member is mounted to the base,
wherein the valve member is deflectable relative to the base between a closed position in which the valve member restricts fluid flow through the discharge opening and an open position in which the valve member allows fluid flow through the discharge opening, and
wherein the discharge opening includes at least one radially extending lobe.
 
12. A compressor comprising:
a scroll including an end plate and a spiral wrap extending from the end plate, the end plate including a discharge passage; and
a discharge valve assembly mounted to the scroll and configured to control fluid flow through the discharge passage, the discharge valve assembly including a base and a valve member, wherein the base is fixed relative to the end plate and includes a discharge opening in communication with the discharge passage, wherein the valve member is mounted to the base,
wherein the valve member is deflectable relative to the base between a closed position in which the valve member restricts fluid flow through the discharge opening and an open position in which the valve member allows fluid flow through the discharge opening,
wherein a first side of the base includes a first seat surface and a second seat surface that is recessed from the first seat surface,
wherein the discharge opening extends through the first and second seat surfaces,
wherein a movable end of the valve member contacts the first seat surface when the valve member is in the closed position and is spaced apart from the first seat surface when the valve member is in the open position, and
wherein the movable end of the valve member contacts the second seat surface when the valve member is in the closed position and is spaced apart from the second seat surface when the valve member is in the open position.
