Problems solved by technology

As a result, the vibration generated due to the linear reciprocating motion of the piston 2 in the cylinder 4 is transmitted to the discharge valve support 18 and the discharge cover 16 in surface contact with the discharge valve support 18 through the discharge valve spring 14, and is amplified to increase noise

Embodiment Construction

[0032] The present invention will now be described in detail with reference to the accompanying drawings.

[0033] Figure 4 is a side sectional view illustrating a discharge valve assembly for a linear compressor according to the present invention; Figure 5 is along Figure 4 A sectional view taken along the line B-B of ; and Image 6 is a perspective view illustrating a discharge valve support applied to a discharge valve assembly for a linear compressor according to the present invention.

[0034] Such as Figure 4As shown, in a discharge valve assembly for a linear compressor, a piston 52 reciprocates linearly within a cylinder 54 to compress the refrigerant. At one end of the cylinder 54 is mounted a discharge valve 62 for opening and closing the cylinder 54 . At one end of the cylinder 54 is fixedly mounted a discharge cover 66 for covering the cylinder 54 and the discharge valve 62 . One end of the helical discharge valve spring 64 elastically supports the discha...

Abstract

The present invention discloses a discharge valve (62) assembly for a linear compressor, comprising: a discharge valve (62) installed at one end of the cylinder (59) to be opened and closed, a compression space (P) for compressing a sucked refrigerant by linear reciprocation of a piston (52) being formed in one end of the cylinder; a discharge cap (66) fixedly installed at one end of the cylinder, for forming a discharge space (D) to which the refrigerant of the compression space is discharged; a discharge valve spring (69) installed between the discharge valve (62) and the discharge cap (66), for opening and closing the discharge valve (62) according to a refrigerant pressure; and a ring-shaped discharge valve supporter (68) installed in the discharge cap (66), having at least one main protrusion directly contacting the inner circumference of the discharge cap (66) 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 (68).

Description

technical field [0001] The invention relates to a discharge valve assembly for a linear compressor, which includes a discharge valve installed at one end of a cylinder and opened and closed by a discharge valve spring, for compressing and sucking into the compression space through the linear reciprocating movement of the piston in the cylinder refrigerant and discharge the compressed refrigerant to the discharge space, and more particularly the present invention relates to a discharge valve assembly for a linear compressor, which can effectively reduce friction-induced wear and limit vibration transmission even when The same is true when the vibration between the piston and the cylinder is transmitted through the discharge valve spring to generate an external force. Background technique [0002] figure 1 is a side sectional view illustrating a conventional discharge valve assembly for a linear compressor, figure 2 is along figure 1 The profile drawn by the line A-A, and ...
