摘要： A linear compressor is provided that may include a shell in which a discharge port may be provided, a cylinder disposed in the shell to define a compression space for a refrigerant, a piston disposed to be reciprocated in an axial direction within the cylinder, a discharge valve disposed on or at one side of the cylinder to selectively discharge the refrigerant compressed in the compression space, a valve spring coupled to the discharge valve to provide a restoring force, and a stopper coupled to the valve spring to restrict deformation of the valve spring. The stopper may include a guide recessed in a direction in which the valve spring is deformed to reduce an impulse between the stopper and the valve spring.

摘要： A method and system for fine-tuning the motion of suction or discharge valves associated with cylinders of a reciprocating gas compressor, such as the large compressors used for natural gas transmission. The valve's primary driving force is conventional, but the valve also uses an electromagnetic coil to sense position of the plate (or other plugging element) and to provide an opposing force prior to impact.
