Abstract

The invention provides an oil supply device and a scroll compressor. The oil supply device comprises an oil storer, a valve and an oil pump, wherein the oil storer is provided with an oil storage cavity; the oil storer is provided with an oil outlet channel, an oil return channel and an oil feeding channel, which all communicate with the oil storage cavity; the oil feeding channel is opened or closed by the valve; and the oil pump is connected with the oil outlet channel. The oil supply device can achieve the stable oil supply effect in various states of the scroll compressor, prevents oil shortage of the compressor, realizes effective oil supply lubrication of each friction of the compressor, and improves the reliability of the scroll compressor and the performances of an air conditioner.

Description

technical field [0001] The invention relates to the technical field of compression devices, in particular to an oil supply device and a scroll compressor. Background technique [0002] Scroll compressors are widely used in the fields of refrigeration, air conditioning and heat pumps because of their high efficiency, small size, light weight, and stable operation. Generally speaking, a scroll compressor is composed of a closed shell, a fixed scroll, a movable scroll, a bracket, a crankshaft, an oil supply device for an anti-rotation mechanism, and a motor. The profiles of the movable and static scrolls are both spiral , The movable scroll is installed eccentrically with respect to the static scroll with a difference of 180°, so multiple crescent-shaped spaces are formed between the movable and static scrolls. When the movable scroll takes the center of the static scroll as the center of rotation and performs non-rotation-translational motion with a certain radius of rotation...
