Embodiment 1

[0035] Such as figure 1 A scroll compressor shown includes a fixed scroll member 2 with a spiral wrap 3, a movable scroll member 15 with a spiral wrap 4, the fixed scroll member and the movable scroll member 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 installed in the top groove of the fixed scroll part and the bottom groove of the movable scroll part. The ring part can prevent the movable scroll part 15 from rotating. There is a communication hole on the movable scroll part. The drive shaft 13 has an oil inlet passage 14. One end of the communication hole is connected to the oil inlet passage, and the other end is connected to the chamber. The lubricating oil is supplied to the chamber. There is an oil passage on the movable scroll part. The oil hole at the end of the oil passage communicates with the groove, and the other e...

Embodiment 2

[0040] Such as Figure 5 As shown, the oil hole 6 on the side of the groove 9 on the bottom surface of the movable scroll part 15 is facing the side of the slider of the cross ring sliding part. The side facing the cross ring sliding part 8, the oil hole is not completely closed to provide lubricating oil; during the rest of the rotary cycle, the oil hole faces the side of the cross ring sliding part, the oil hole is completely closed, in this compressor Here, lubricating oil is only provided during the limited phases of the scroll compressor cycle, when the holes are alternately opened and closed, relying on constraints such as pressure differences to regulate the flow of oil and control the amount of oil. The lubricating oil is supplied to the mating surface formed by the fixed scroll member and the movable scroll member through the channel communicated with the groove provided on the top of the fixed scroll member.

Embodiment 3

[0042]Such as Figure 6 As shown, the oil hole 6 on the side of the groove 9 on the bottom surface of the movable scroll part 15 faces the side of the cross ring sliding part. During the whole revolution cycle, the cross ring sliding part slides in the groove of the movable scroll element , during the whole cycle of the cross-ring sliding part 8, the side of the cross-ring sliding part does not cover the oil hole, and the lubricating oil is always supplied in the whole cycle of the movable scroll element's rotary motion. By controlling the diameter of the oil hole and the pressure difference at both ends of the oil hole, the amount of oil entering the groove at the bottom of the movable scroll element is controlled.

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 ...
