1. Field of the Invention
This invention relates to a mute compressor, particularly to one having its driving gear and driven mechanism completely surrounded by a positioning base so as to tremendously lower operating noise.
2. Description of the Prior Art
As shown in
The object of this invention is to offer a mute compressor able to greatly lower its noise created while operating.
The main characteristics of the invention are a driving motor, a positioning base fixed at one side of the driving motor, a driven mechanism and a cylinder fixed above the positioning base. With the driving gear and the driven mechanism confined in a chamber sealed with a lid in the positioning base, the noise created while operating the mute compressor can be isolated by the positioning base to get minimized.
This invention is better understood by referring to the accompanying drawings, wherein:
As shown in
The driving motor 2 is provided with a driving gear 20 positioned at one end, and a cooling fan 21 fixed at another end.
The positioning base 3 is provided with a chamber 30 formed inside it for accommodating the driving gear 20 and the driven mechanism 4 therein, and a lid 31 employed to fixedly cover the chamber 30 by means of plural screws 32.
The driven mechanism 4 is provided with a driven gear 40, a shaft 41 fixed in the center of the driven gear 40, a cam 42 positioned on the shaft 41, and an eccentric shaft 43 fixed eccentrically on the cam 42.
The cylinder 5 is installed on the positioning base 3, provided with a piston 50, a piston rod 51 having one end fixed at the bottom of the piston 50 and another end pivotally connected with the eccentric shaft 43.
It is to be noted that, with the driving gear 20 of the driving motor 2 and the driven mechanism 4 confined in the chamber 30 sealed with the lid 31, the noise created during operation of the driven mechanism 4 driven by the driving gear 20 can be blocked by the positioning base 3 to be mostly lessened, achieving a noise-muting function.
While the preferred embodiment of the invention has been described above, it will be recognized and understood that various modifications may be made therein and the appended claims are intended to cover all such modifications that may fall within the spirit and scope of the invention.
