The first oil groove 101 is disposed at an outer region of the scroll groove 120 of the fixed scroll 100 and is integrally located within an operation range of the end plate of the movable scroll 200, and the first oil groove 101 may be at least partially disposed around the outer circumference of the scroll groove 120 to avoid communication between the first oil groove 101 and the back pressure chamber of the movable scroll 200.

In practical application, since the scroll groove 120 extends in a vortex shape, the suction end 120a of the scroll groove 120 is located in the area of the fixed scroll 100 near the outer side, and the discharge end of the scroll groove 120 is located in the area of the fixed scroll 100 near the center, then a solid area with a larger area exists on the end face of the scroll groove 120 in the direction of vortex extending on the suction end 120a side, and the oil section of the first oil groove 101 near the suction end 120a is bent outwards in this area to adapt to the vortex shape of the scroll groove 120, so that there may be insufficient lubrication at the position near the suction end 120a of the scroll teeth 120 to wear. Based on this, the present embodiment provides the first oil inlet portion 101a at a position of the first oil groove 101 near the suction end 120a of the scroll 120, and the first oil outlet 201a periodically communicates with the first oil inlet portion 101a, so that more lubricating oil is supplied to the first oil inlet portion 101a, increasing the lubrication effect of the scroll at a position near the suction end 120 a.

Alternatively, the first oil groove 101 may be an annular groove or a "C" shaped groove.

Further, the second oil groove 202 is periodically communicated with the first oil inlet 101 a. As can be seen from the foregoing embodiments, the oil supply area and the oil quantity at the first oil inlet portion 101a are larger than those at other areas of the first oil groove 101, and in this embodiment, the second oil groove 202 is periodically communicated with the first oil inlet portion 101a, so that when the second oil groove 202 is communicated with the first oil inlet portion 101a, the lubricating oil can more quickly enter the second oil groove 202 for storage, and further, when the second oil groove 202 is not communicated with the first oil inlet portion 101a, enough lubricating oil is provided in the second oil groove 202 to supply oil and lubricate the area between the first oil inlet portion 101a and the air suction end 120a, thereby further improving the oil supply efficiency and promoting the quick and sufficient lubrication of the whole end surface area of the scroll.

In an embodiment of the present utility model, referring to fig. 2, 6 and 7, a third oil groove 102 is further disposed on an end surface of the fixed scroll 100, and the third oil groove 102 is disposed at a side of the first oil groove 101 away from the scroll groove 120; the first oil outlet 201a is periodically communicated with the third oil groove 102, and the second oil groove 202 does not communicate the first oil groove 101 with the third oil groove 102.

As can be seen from the refrigerant pressure distribution, the first oil groove 101 close to the scroll groove 120 is a high-pressure oil groove, and the third oil groove 102 far from the scroll groove 120 is a medium-pressure oil groove. In this embodiment, when the orbiting scroll 200 moves, the first oil outlet 201a can be driven to periodically communicate with the first oil groove 101 and the third oil groove 102, respectively, so as to supply oil to the first oil groove 101 and the third oil groove 102.

Alternatively, the projected shape of the second oil groove 202 on the end surface of the orbiting scroll 200 is in the shape of an arc. The circular arc opening of second oil groove 202 can set up towards first oil-out 201a, and the extending direction of second oil groove 202 and the circumference of moving vortex dish 200 become the contained angle to at the motion in-process of moving vortex dish 200, can drive second oil groove 202 and sweep along the broad line of sweeping, so set up can increase sweep area and sweep efficiency, further promote lubrication efficiency. Further, the second oil groove 202 can be far away from the circumference where the first oil outlet 201a is located at one end of the center of the movable scroll 200, and the arrangement can ensure that the second oil groove 202 is not communicated with the medium-pressure third oil groove 102 in the whole movement period, so that the structural reliability of the scroll is improved.

In one embodiment, the first oil groove 101 is annularly surrounded on the outer circumference of the scroll groove 120, and the third oil groove 102 is annularly spaced around the outer circumference of the first oil groove 101.
