Example Embodiment

[0034] Example 1

[0035] Such as figure 1 The scroll compressor shown includes a fixed scroll part 2 with a spiral scroll tooth 3, an orbiting scroll part 15 with a spiral scroll tooth 4, the fixed scroll part and the movable scroll part The spiral scroll teeth cooperate with each other to form a compression chamber. The movable scroll part circulates relative to the fixed scroll part under the action of the drive shaft. A cross is slid in the top groove of the fixed scroll part and the bottom groove of the movable scroll part. The annular component can prevent the orbiting scroll component 15 from rotating. The orbiting scroll component is provided with a communicating hole. The drive shaft 13 has an oil inlet passage 14. One end of the communicating hole communicates with the oil inlet passage and the other end communicates with the chamber. The lubricating oil is supplied to the chamber. An oil passage is opened on the movable scroll component. The oil hole at the end of the ...

[0039] Example 2

[0040] Such as Figure 5 As shown, the oil hole 6 on the side surface of the groove 9 on the bottom surface of the movable scroll component 15 is opposite to the side surface of the slider of the cross-shaped sliding component. When the movable scroll component rotates, during a part of its rotation cycle, the oil hole On the side of the cross ring sliding part 8, the oil hole is not completely closed and can provide lubricating oil; during the rest of the rotation cycle, the oil hole faces the side of the cross ring sliding part, and the oil hole is completely closed. In this type of compressor Here, lubricating oil is provided only in the limited phase of the scroll compressor cycle. When the holes are alternately opened and closed, the pressure difference and other constraints are used to adjust the oil flow and control the amount of oil. The lubricating oil is supplied to the mating surface formed by the fixed scroll part and the movable scroll part through ...

Example Embodiment

[0041] Example 3

[0042]Such as Figure 6 As shown, there is an oil hole 6 on the side surface of the groove 9 on the bottom surface of the movable scroll component 15 and the oil hole faces the side surface of the cross-shaped sliding component. During the entire rotation cycle, the cross-shaped sliding component slides in the groove of the movable scroll component. During the entire cycle of the cross-shaped sliding part 8, the side of the cross-shaped sliding part does not cover the oil hole, and the lubricating oil is always supplied during the entire cycle of the orbiting scroll element making a rotary motion. The amount of oil entering the groove at the bottom of the orbiting scroll element is controlled by controlling the diameter of the oil hole and the pressure difference between the two ends of the oil hole.

Abstract

The present invention relates to a compressor, in particular to a scroll compressor with a lubricating system, an oil channel is arranged on a movable swirl part, and the end oil hole of the oil channel is communicated with a socket to feed lubricant to a cross ring-shaped moving part in the socket. The present invention improves the lubricating system of the scroll compressor, so that the lubricant can be fed into a chamber formed by a fixed swirl part and the movable swirl part via a specific channel, and the oil hole can be periodically opened in order to accurately control the flow of the lubricant into the chamber, so that the chamber can be better lubricated. Thereby, the scroll compressor can be better lubricated in the process of operation, and meanwhile, the quantity of the lubricant fed into the chamber can be accurately controlled in order to ensure the stability of operation and obtain higher compressing efficiency.

Description

1. Technical field [0001] The present invention relates to refrigeration compressors, particularly scroll compressors. 2. Background technology [0002] Scroll compressors have been widely used in refrigeration compression. As we all know, scroll compressors include a fixed scroll part and a movable scroll part. They have spiral scroll teeth that cooperate with each other. The spiral tooth forms a chamber. When the movable scroll part moves relative to the fixed scroll part, in order to prevent the movable scroll part from rotating during the movement, a cross ring sliding part is placed in the bottom groove, which can effectively prevent The movable scroll part rotates by itself. However, during the sliding process of the cross ring sliding part in the groove at the bottom of the movable scroll part, if the lubricating oil is not sufficient, the side surface of the cross ring sliding part slider will be scratched and worn, which will deteriorate the running condition, and ...
