4 results about "Linear compressor" patented technology

The present invention provides a linear compressor, including: a cylinder having a compression space of refrigerant therein; a piston linearly reciprocated inside the cylinder in an axis direction to compress the refrigerant; and a frame having a mounting hole so that one end of the cylinder can be mounted thereon, and also having a deformation prevention portion in some section around the mounting hole brought into contact with the one end of the cylinder. Even though the size of the cylinder is increased and the size of the frame is limited, the frame is provided with enough strength to support the cylinder, thereby reducing fastening deformations and improving operation reliability.

An aerostatic bearing and a linear compressor that includes the aerostatic bearing. In an exemplary embodiment, the aerostatic bearing includes a guide element including holes, and a body structured to move along a surface of the guide element. The holes may include a first section close to the body, of which at least one part area features a cross-sectional surface substantially constant over its entire length which is smaller towards the body than another cross-sectional surface of an area away from the body. A method for producing a hole in an element, using a laser beam, for producing the aerostatic bearing is also disclosed.

A linear compressor according to the present disclosure may include a piston reciprocating within a cylinder; a motor providing a driving force for the motion of the piston; a sensing unit configuredto sense a motor voltage and a motor current associated with the motor; a discharge portion provided at one end of the cylinder to regulate the discharge of refrigerant compressed in the cylinder; a control unit configured to compute at least one control parameter associated with the motion of the piston using at least one of the motor voltage and the motor current sensed by the sensing unit; anda deep learning operation unit configured to receive the control parameter, and output a compensation value associated with an absolute position of the piston using artificial neural network technology.
