Oil supply device for horizontal type rotary compressor

Abstract

The invention provides an oil supply device for a horizontal type rotary compressor, which comprises a compression part, a motor part and an oil storage part which are arranged in a shell, as well as lubricating oil, wherein the compression part and the oil storage part are located in a low pressure area, the compression part is communicated with the oil storage part through an oil sucking channel or an oil sucking pipe, the motor part is located in a high pressure area, the low pressure area is communicated with the high pressure area, a non-return mechanism for preventing the lubricating oil from flowing to the motor part from the oil storage part is arranged at the communication part of the low pressure area and the high pressure are, the non-return mechanism is provided with a valve block arranged in a valve seat in a sliding manner, an oil hole which is plugged by the valve block is arranged in the valve seat, the valve block is closed to the oil storage part side, the oil hole is close to the motor part side, and the end of the valve block, facing the oil hole, is wedge-shaped. When the horizontal type rotary compressor is in an inclined state, the lubricating oil can be effectively prevented from flowing to the motor part from the oil storage part; and the oil supply device has the characteristics of simple and reasonable structure, high operation flexibility, low manufacturing cost and long service life.

Description

technical field [0001] The invention relates to a horizontal rotary compressor, in particular to an oil supply device for the horizontal rotary compressor. Background technique [0002] The horizontal rotary compressor is different from the vertical compressor in that the horizontal rotary compressor cannot rely solely on the rotating centrifugal force of the shaft to satisfy the supply of lubricating oil in the compression part. Therefore, most of the horizontal rotary compressors supply lubricating oil from the oil storage part of the horizontal rotary compressor to the compression part by pressure difference or forced pressure feeding. [0003] Generally, most horizontal rotary compressors are installed in static household air conditioners, but sometimes a small number of horizontal rotary compressors are used in dynamic vehicles. When it is used on a vehicle, due to different road conditions, the external force that causes the vehicle to sway from side to side or vibrat...

AI Technical Summary

Problems solved by technology

However, in actual operation, the vehicle will sway from side to side and vibrate up and down at the same time, so it is impossible to completely prevent the lubricating oil in the horizontal rotary compressor from flowing to the motor part.

In addition, the lubricating oil flowing to the motor part cannot return to the oil storage part immediately when the vehicle returns to the level road surface, so there will be a situation of oil shortage
