1. A thrust plate for use in a scroll compressor, the thrust plate comprising:
a disk-shaped body defining a plane and having a first side and a second side, wherein the second side opposes the first side, wherein the disk-shaped body comprises a plurality of holes, which extend from a surface of the first side to a surface of the second side and which are configured to receive pins of an Oldham coupling;
at least one protrusion extending from the first side; and
at least one recess located at the second side;
wherein the at least one protrusion and the at least one recess overlap at least partially in a direction perpendicular to the plane, wherein the at least partial overlap is defined by the at least one protrusion overlapping entirely with the at least one recess.
 
12. A system comprising:
a thrust plate comprising:
a disk-shaped body defining a plane and having a first side and a second side, wherein the second side opposes the first side, wherein the disk-shaped body comprises a plurality of holes, which extend from a surface of the first side to a surface of the second side and which are configured to receive pins of an Oldham coupling, and
at least one protrusion extending from the first side; and
an orbiting scroll plate having a base plate with a frontside and a backside, wherein the orbiting scroll plate comprises at least one recess located at its backside;
wherein the backside of the orbiting scroll plate at least partially abuts at least a portion of the second side of the thrust plate, and
wherein the at least one protrusion and the at least one recess overlap at least partially in a direction perpendicular to the plane, wherein the at least partial overlap is defined by the at least one protrusion overlapping entirely with the at least one recess.
