20090081054 | Structure of Discharging Refrigerant For Linear Compressor - The present invention discloses a linear compressor in which a piston is linearly reciprocated inside a cylinder, for sicking a refrigerant into a compression space between the piston and the cylinder, and compressing and discharging the refrigerant, and especially, a structure of discharging the refrigerant for the linear compressor which can reduce a pulsation of a high pressure discharged refrigerant, by making the refrigerant compressed in the compression space flow from a sub-discharge space with a relatively small volume to a sub-discharge space with a relatively large volume in a discharge chamber. As a result, the structure of discharging the refrigerant for the linear compressor can efficiently reduce noise and vibration. | 03-26-2009 |
20090095572 | Oil Valve Assembly of Linear Compressor - The present invention discloses an oil supply valve assembly of a linear compressor including a shell, the oil being stored at the lower portion of the shell, a cylinder disposed in the shell, a piston disposed in the cylinder, a main body frame to which the cylinder is fixed, and a linear motor connected to the piston, for driving the piston, comprising: a passage formed in the main body frame, for supplying the oil to a gap between the cylinder and the piston; an oil valve being coupled to the main body frame to communicate with the passage, and including an oil suction valve and an oil discharge valve; and an oil cover coupled to overlap with the oil valve and communicate with the passage of the main body frame. By this configuration, the manufacturing process of the oil supply valve assembly is simplified and mis-assembly of the components is prevented by reducing the number of the components. | 04-16-2009 |
20090220365 | Discharge Valve Assembly For Linear Compressor - The present invention discloses a discharge valve assembly for a linear compressor, comprising: a discharge valve installed at one end of the cylinder to be opened and closed, a compression space for compressing a sucked refrigerant by linear reciprocation of a piston being formed in one end of the cylinder, a discharge cap fixedly installed at one end of the cylinder, for forming a discharge space to which the refrigerant of the compression space is discharged; a discharge valve spring installed between the discharge valve and the discharge cap, for opening and closing the discharge valve according to a refrigerant pressure; and a ring-shaped discharge valve supporter installed in the discharge cap, having at least one main protrusion directly contacting the inner circumference of the discharge cap and at least one auxiliary protrusion disposed with an interval from the inner circumference of the discharge cap being formed on the outer circumference of the discharge valve supporter. | 09-03-2009 |
20100034676 | Mounting Structure of Linear Compressor - The present invention discloses a mounting structure of a linear compressor, comprising: a shell which is a hermetic space, a connection terminal for supplying power being fixed to one side of the shell; a main body frame installed in the shell, one end of a cylinder forming a compression space for compressing a refrigerant with a piston being fixed to the main body frame; and a motor cover, a linear motor comprised of an inner stator, an outer stator and a mover, for reciprocating the piston by a mutual electromagnetic force being fixed to the outer circumference of the cylinder, the outer stator being bolt-fastened between the main body frame and the motor cover. Here, the main body frame is left-right symmetric. | 02-11-2010 |
