Abstract

The present invention relates to a vane rotary compressor in which, while a rotor is rotating, the volume of a compressing chamber is reduced and a fluid such as a refrigerant is compressed. The vane rotary compressor according to one embodiment of the present invention is provided with the compressing chamber, the inner circumferential surface of which is formed in the shape of an involute curve, wherein the rotor is hinge-coupled with a plurality of cantilever vanes such that compression efficiency is high and noise is prevented from occurring during the operation of the compressor.

First claim

The invention claimed is:

1. A vane rotary compressor comprising:
a hollow cylinder ( 200 ), an inner peripheral surface of the hollow cylinder is formed in the form of an involute curve along a circumferential direction of the hollow cylinder;
a front housing ( 300 ) which is formed therein with a space portion so as to install the cylinder ( 200 ) and is opened at the rear of the space portion;
a rear housing ( 400 ) which is coupled to a rear end of the front housing ( 300 ) to close the space portion;
a rotor ( 600 ) which is installed within the cylinder ( 200 ) and rotates by receiving power of a drive source from a rotary shaft ( 500 ); and
a vane ( 700 ) which is hinge-coupled, at a first end of the vane, to an outer peripheral surface of the rotor ( 600 ) while a second end of the vane ( 700 ) comes into contact with the inner peripheral surface of the cylinder ( 200 ) along with rotation of the rotor ( 600 ), wherein one side of an outer peripheral surface of the front housing ( 300 ) protrudes outwardly to form an oil room ( 331 ).

2. The vane rotary compressor according to claim 1 , wherein the vane ( 700 ) is provided in plural numbers, the plural vanes ( 700 ) being spaced apart from each other in a circumferential direction of the rotor ( 600 ).

3. The vane rotary compressor according to claim 1 , wherein an outside surface of the vane ( 700 ) is formed by a curvature corresponding to the outer peripheral surface of the rotor ( 600 ).

4. The vane rotary compressor according to claim 3 , wherein the outer peripheral surface of the rotor ( 600 ) is formed with an accommodation groove ( 630 ) to accommodate the vane ( 700 ), and when the vane ( 700 ) is accommodated into the accommodation groove ( 630 ), the outside surface of the vane ( 700 ) and the outer peripheral surface of the rotor ( 600 ) form a circumferential surface having the same curvature.

5. A vane rotary compressor comprising:
a hollow cylinder ( 200 ), an inner peripheral surface of the hollow cylinder is formed in the form of an involute curve along a circumferential direction of the hollow cylinder;
a front housing ( 300 ) which is formed therein with a space portion so as to install the cylinder ( 200 ) and is opened at the rear of the space portion;
a rear housing ( 400 ) which is coupled to a rear end of the front housing ( 300 ) to close the space portion;
a rotor ( 600 ) which is installed within the cylinder ( 200 ) and rotates by receiving power of a drive source from a rotary shaft ( 500 ); and
a vane ( 700 ) which is hinge-coupled, at a first end of the vane, to an outer peripheral surface of the rotor ( 600 ) while a second end of the vane ( 700 ) comes into contact with the inner peripheral surface of the cylinder ( 200 ) along with rotation of the rotor ( 600 ), wherein one side of an outer peripheral surface of the cylinder ( 200 ) is recessed to form an oil room ( 332 ).

6. The vane rotary compressor according to claim 5 , wherein the vane ( 700 ) is provided in plural numbers, the plural vanes ( 700 ) spaced apart from each other in a circumferential direction of the rotor ( 600 ).

7. The vane rotary compressor according to claim 5 , wherein an outside surface of the vane ( 700 ) is formed by a curvature corresponding to the outer peripheral surface of the rotor ( 600 ).

8. The vane rotary compressor according to claim 7 , wherein the outer peripheral surface of the rotor ( 600 ) is formed with an accommodation groove ( 630 ) to accommodate the vane ( 700 ), and when the vane ( 700 ) is accommodated into the accommodation groove ( 630 ), the outside surface of the vane ( 700 ) and the outer peripheral surface of the rotor ( 600 ) form a circumferential surface having the same curvature.

9. A vane rotary compressor comprising:
a hollow cylinder ( 200 ), an inner peripheral surface of the hollow cylinder is formed in the form of an involute curve along a circumferential direction of the hollow cylinder;
a front housing ( 300 ) which is formed therein with a space portion so as to install the cylinder ( 200 ) and is opened at the rear of the space portion;
a rear housing ( 400 ) which is coupled to a rear end of the front housing ( 300 ) to close the space portion;
a rotor ( 600 ) which is installed within the cylinder ( 200 ) and rotates by receiving power of a drive source from a rotary shaft ( 500 ); and
a vane ( 700 ) which is hinge-coupled, at a first end of the vane, to an outer peripheral surface of the rotor ( 600 ) while a second end of the vane ( 700 ) comes into contact with the inner peripheral surface of the cylinder ( 200 ) along with rotation of the rotor ( 600 ), wherein a lower end of a cylinder portion ( 310 ) of the front housing ( 300 ) protrudes outwardly to form a pair of oil rooms ( 333 ) ( 334 ), the pair of oil rooms ( 333 ) ( 334 ) spaced apart from each other.

10. The vane rotary compressor according to claim 9 , wherein one side of the rear housing ( 400 ) is formed with an oil passage ( 420 ) to guide a flow of oil from one side of one of the pair of oil rooms ( 333 ) ( 334 ) to a rear end of the rotary shaft ( 500 ).

11. The vane rotary compressor according to claim 10 , wherein both front and rear sides of the rotor ( 600 ) respectively come into contact with the front housing ( 300 ) and the rear housing ( 400 ), and a plurality of rotor passages ( 610 ) axially formed to penetrate the rotor ( 600 ), thereby allowing oil supplied through the oil passage ( 420 ) to lubricate a rear end sliding surface of the rotor ( 600 ) while lubricating a front end sliding surface of the rotor ( 600 ) through the rotor passages ( 610 ).
