Problems solved by technology

Therefore, noise is generated, or the movement of the exhaust valve 5 is unstable
[0020] Also, if the metal mold gate is provided on the side surface of the exhaust valve 5, the molded product may be distorted due to the flow characteristics of the injected medium, and the movement of the exhaust valve becomes inconsistent due to the different density of the medium after molding. Stable, thus producing exhaust noise
In addition, if the gate is arranged in the direction of the bearing surface portion 14, there is no machining allowance for post-processing, so it is difficult to manufacture

Embodiment Construction

[0039] Hereinafter, the present invention will be described with reference to the accompanying drawings. Furthermore, parts that are identical to those of the prior art bear the same reference numerals.

[0040] Such as Figure 6 and Figure 7 As shown, the exhaust valve device of the reciprocating compressor according to the present invention includes: an exhaust cover 103, which is installed in a certain exhaust space S2 in a fixed manner, and is arranged on the front end surface of the cylinder 2, so as to cover the cylinder 2, the piston 1 is inserted into the cylinder 2; the exhaust valve 104, which is arranged on the inside of the exhaust cover 103, is used to open by contacting / separating the front end surface of the cylinder 2 when the piston 1 reciprocates. / close cylinder 2; and valve spring 105, its two ends are supported by the inner surface of exhaust cover 103 and the rear surface of exhaust valve 104 facing the inner surface direction of exhaust cover 103.

Abstract

The invention provides an exhaust valve device for a reciprocating compressor, which comprises: an exhaust cover with a built-in volume for covering the front end surface of the cylinder; A moving piston is in contact with / separated from the front end surface of the cylinder; and a valve spring, both ends of which are respectively attached to the rear side of the exhaust valve and to the inner surface of the exhaust cover, so as to elastically support the rear side of the exhaust valve. The radius of rotation of the conical valve spring is set to decrease or increase, which prevents one part from colliding with another part during compression. Therefore, when the valve spring is compressed according to the compression of the piston and the exhaust stroke, the collision noise generated by the collision of the parts inside the valve spring can be prevented in advance.

Description

field of invention [0001] The invention relates to an exhaust valve device of a reciprocating compressor, in particular to a shape of a valve spring applied to a valve assembly of a reciprocating compressor and a manufacturing method of the exhaust valve. Background technique [0002] Generally, among the valve assemblies of general reciprocating compressors, the axial exhaust valve assembly is a device in which a piston integrated with an armature of an electric motor reciprocates linearly in a cylinder, suction Refrigerant gas, compresses the refrigerant gas and discharges it in the direction of movement of the piston. In addition, the opening / closing speed of the exhaust valve is closely related to the function of the entire exhaust valve assembly. When the piston reciprocates, the exhaust valve is opened / closed. [0003] figure 1 and FIG. 2 are a perspective view and a longitudinal sectional view showing an embodiment of the above-mentioned axial type exhaust valve as...
