Abstract
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.
