Preferably, a cross 12 is further provided to prevent the orbiting scroll 8 from rotating.

The second oil supply passage is provided on the side close to the exhaust pipe 14, and oil supply is performed by the oil pump 13 provided in the sub-bearing support 3.

The first oil supply passage is provided on the side of the suction pipe 11, and has one end opened in the lubricating oil and the other end opened in the cavity formed by the main bearing support 6 and the movable scroll 8. The movable scroll 8 is provided with an oil hole 15, one side of the oil hole 15 is connected with a cavity formed by the movable scroll 8 and the crankshaft 5, the other side of the oil hole 15 is connected with a third guide groove 18 arranged at the top of the movable scroll 8, and furthermore, the oil hole 15 is arranged at one side, close to the center, of the movable scroll 8.

Preferably, a second guide groove 17 is provided on a contact surface between the crankshaft 5 and the orbiting scroll 8 in order to connect a cavity formed by the crankshaft 5 and the main bearing support 6 and a cavity formed by the crankshaft 5 and the orbiting scroll 8.

Preferably, a first guide groove 16 is provided on a contact surface between the crankshaft 5 and the main bearing support 6 in order to lubricate the main bearing support 6.

The pressure close to the center side of the movable vortex 8 is higher but is smaller than the exhaust pressure; the side remote from the centre of the orbiting scroll 8 is at a lower pressure but slightly above the suction pressure.

The pressure of the sealed space is high, the pressure of the cavity formed by the main bearing support 6 and the movable scroll 8 is low, the lubricating oil is sucked into the cavity formed by the main bearing support 6 and the movable scroll 8 and enters the third guide groove 18 through the oil hole 15 arranged in the movable scroll 8, and the pressure of the center of the movable scroll 8 is higher than that of the outer side, so that the lubricating oil sucked into the third guide groove 18 spreads to the outside of the movable scroll 8 through the third guide groove 18, and the oil supply to the friction pair is realized.

Preferably, as shown in fig. 2, the length of the third guide groove 18 is smaller than the length of the orbiting scroll 8.

In the process, a part of lubricating oil in a cavity formed by the movable scroll 8 and the main bearing support 6 enters a cavity formed by the movable scroll 8 and the crankshaft 5 through the first guide groove 16 and enters the oil hole 15, and meanwhile, the main bearing support 6 is lubricated; the other part enters a cavity formed by the movable scroll 8 and the crankshaft 5 through the second guide groove 17 and enters the oil hole 15, and lubrication of the contact surface of the crankshaft 5 and the movable scroll 8 is realized.

Preferably, a seal 7 is provided between the main bearing support 6 and the orbiting scroll 8 to prevent communication between the low pressure region and the high pressure region.

Example one

In the present embodiment, when the oil pump 13 is at a low position, for example, when a vehicle on which the compressor is mounted is climbing a slope or descending a slope, the lubricating oil is concentrated on the oil pump 13 side.

If the oil suction inlet of the first oil supply channel is still immersed in the lubricating oil, the first oil supply channel and the second oil supply channel work normally, and oil supply to each friction pair is realized.

If the oil suction inlet of the first oil supply channel is completely exposed in the air and loses the oil supply capacity, oil is supplied to each friction pair only through the second oil supply channel, and structural components are prevented from being damaged when the oil supply is insufficient.

Example two

In the present embodiment, when the oil pump 13 is at a high position, for example, when a vehicle on which the compressor is mounted is climbing a slope or descending a slope, the lubricating oil is concentrated on the first oil supply passage side.

If the oil suction inlet of the second oil supply channel is still immersed in the lubricating oil, the first oil supply channel and the second oil supply channel both work normally, and oil supply to each friction pair is realized.

If the oil suction inlet of the second oil supply channel is completely exposed in the air and the second oil supply channel loses the oil supply capacity, oil is supplied only through the first oil supply channel.

Due to the pressure difference, the lubricating oil is sucked into the chamber formed by the main bearing support 6 and the orbiting scroll 8, and enters the chamber formed by the crankshaft 5 and the orbiting scroll 8 through the first guide groove 16 or the second guide groove 17.

Lubricating oil enters a cavity formed by the crankshaft 5 and the movable scroll 8 through the first guide groove 16 and simultaneously lubricates the main bearing support 6; the lubricating oil lubricates the contact surfaces of the crankshaft 5 and the orbiting scroll 8 while entering the chamber formed by the crankshaft 5 and the orbiting scroll 8 through the second guide groove 17.

Then, because the pressure in the chamber formed by the crankshaft 5 and the movable scroll 8 is slightly less than the exhaust pressure, the lubricating oil inside the chamber enters the third guide groove 18 through the oil hole 15, and because the pressure at the position of the oil hole 15 is slightly higher than the pressure outside the movable scroll 8, the lubricating oil inside the third guide groove 18 spreads through the third guide groove 18 to supply oil to the friction pair.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and although the present invention has been disclosed with reference to the above preferred embodiment, but not to limit the present invention, any person skilled in the art can make modifications or changes to equivalent embodiments using the above-mentioned teachings without departing from the scope of the present invention, and the embodiments in the above embodiments can be further combined or replaced, but any simple modification, equivalent changes and modifications made to the above embodiments according to the technical spirit of the present invention are also within the scope of the present invention.
