Problems solved by technology

[0010] However, in the above-mentioned conventional scroll compressor, the amount of oil supplied by the oil pump 23 increases in proportion to the rotation speed of the compressor, and when the compressor operates at a high speed and the amount of oil supplied to the compression portion increases, the amount of oil supplied is excessive.
Therefore, the discharged oil also increases, and there is a problem that the volumetric efficiency of the compressor decreases.

Embodiment Construction

[0022] Such as image 3 As shown, the scroll compressor of the present invention includes a fixed scroll 51 and an orbiting scroll 53, both of which cooperate with each other to form a compression cavity, so that the refrigerant can be compressed in the compression cavity; the crankshaft 61, One end is connected to the orbiting scroll member 53 so that the orbiting scroll member 53 rotates, and an oil passage is formed through the center of the crankshaft 61 through which oil supplied by the oil pump 63 passes. An oil discharge port 67 is formed on the crankshaft 61 to discharge the oil flowing through the oil passage 62 to the outside of the crankshaft 61; a bypass member 69 is arranged on the oil discharge port 67, controlled by the centrifugal force of the oil generated by the rotation of the crankshaft 61, according to The rotational speed of the crankshaft 61 opens or closes the oil discharge port.

[0023] Such as Figure 4 and 5 As shown, the bypass member 69 include...

Abstract

In the vortex compressor, the crankshaft has one oil exhaust port to make partial engine oil flowing through the crankshaft oil path exhaust outside and one bypass part installed to the oil exhaust port for the centrifugal force of engine oil produced by the rotating crankshaft to open or close the oil exhaust port. When the compressor runs at high speed, partial oil flowing through the crankshaft is exhausted outside and returned to oil storage. Thus, the present invention can avoid oversupply of oil to compressing part, reduce engine oil consumption and raise the volume efficiency of compressor.

Description

technical field [0001] The present invention relates to a scroll compressor, in particular to a scroll compressor with such a structure that when the scroll compressor operates at high speed, part of the oil flowing through the crankshaft oil circuit can flow out of the crankshaft. Background technique [0002] Such as figure 1 As shown, in a common scroll compressor, the fixed scroll 1 and the orbiting scroll 3, each of which is an involute scroll, cooperate with each other face to face, and the fixed scroll 1 and the orbiting scroll Many large and small crescent-shaped compression pockets P are formed on the side and bottom surfaces of the scroll member 3 . Here, the involute wrap of the orbiting scroll 3 is set to have a phase difference of 180° with respect to the involute wrap of the fixed scroll 1 . [0003] In the above structure, when the orbiting scroll 3 orbits relative to the fixed scroll 1, since the crescent-shaped compression chamber faces the fixed scroll 1 ...
