Problems solved by technology

However, friction between the piston and a wall of the chamber can negatively affect operation of the linear compressors if the piston is not suitably aligned within the chamber.
In particular, friction losses due to rubbing of the piston against the wall of the chamber can negatively affect an efficiency of an

Abstract

A linear compressor is provided. The linear compressor includes a piston. The piston includes a piston cylinder having a head plate. The head plate defines a passage that extends through the head plate. A reed valve is mounted to the head plate and positioned over the passage of the head plate. A valve seat is positioned at and extends about the passage of the head plate.

Description

FIELD OF THE INVENTION[0001]The present subject matter relates generally to linear compressors, e.g., for refrigerator appliances.BACKGROUND OF THE INVENTION[0002]Certain refrigerator appliances include sealed systems for cooling chilled chambers of the refrigerator appliance. The sealed systems generally include a compressor that generates compressed refrigerant during operation of the sealed system. The compressed refrigerant flows to an evaporator where heat exchange between the chilled chambers and the refrigerant cools the chilled chambers and food items located therein.[0003]Recently, certain refrigerator appliances have included linear compressors for compressing refrigerant. Linear compressors generally include a piston and a driving coil. The driving coil receives a current that generates a force for sliding the piston forward and backward within a chamber. During motion of the piston within the chamber, the piston compresses refrigerant. However, friction between the pisto...
