Abstract
The utility model relates to a cylinder with an oil groove of an oscillating piston-type compressor; wherein, an oil groove is arranged on the inner wall on both sides of a sliding-block hole in the cylinder. When the compressor rotates, lubricating oil stored in the oil groove can have lubricating function, so, the lubrication between the external round and inner wall of the hole of the sliding block is improved and the reliability of the compressor is enhanced, and the oil groove also has the function of receiving abrasive dusts.
Description
Technical field: the utility model relates to the wobble-piston type compressor that is used for air conditioner, refrigerator and refrigerating machine, refers to the improvement to compresser cylinder especially.
Background technique:
Existing wobble-piston type compressor mainly constitutes (referring to Fig. 1, Fig. 2) by parts such as motor 2, cylinder 7, upper cylinder cover 3, following cylinder cap 5, integral piston 4, slide block 6, eccentric shafts 8.Wherein, upper cylinder cover 3, cylinder 7, piston 4, slide block 6, following cylinder cap 5 form swept volumes.Integral piston 4 is processed into one or is set into one by piston body 41 and blade 42, is set on the eccentric shaft 8, places the piston cavity 71 of cylinder 7; Slide block 6 is made of two semicylinders 61,62, places the slider bore 72 of cylinder 7, and can swing in this slider bore.Motor 2 drives the piston cavity inwall swing of piston 4 along cylinder 7 by eccentric shaft 8, blade 42 on the piston 4 is by the support of slide block 6, in cylinder 7, move reciprocatingly and swing, finish the work cycle of gas suction-compression-discharge, and the volume in the cylinder piston chamber is divided into low pressure (air-breathing) chamber 13 and high pressure (compression) chamber 14.
For preventing gas leakage, the gap design between the inwall of slide block 61 and 62 cylindrical and slider bore 72 gets very little, and lubricant oil is difficult to enter this gap, causes the friction and wear of the inwall of the cylindrical of slide block 61 and 62 and slider bore 72 to increase.
Summary of the invention:
In view of the existing problem of said structure, the utility model is intended to propose a kind of wobble-piston type compressor cylinder that has oil groove, the store oil function of its slider bore oil groove of mat is improved the lubricating status between slide block cylindrical and the cylinder slider bore inwall, thereby reduce the friction and wear of its contact position, improve the reliability of compressor operating.
A kind of wobble-piston type compressor cylinder that has oil groove of the present utility model is provided with oil groove on the inwall of the both sides of the slider bore of described cylinder.
The utility model has the advantages that, after oil groove is left in the slider bore both sides of cylinder, when compressor operation, because in the vane hole 12 is high pressure gas pressure, its pressure is higher than the pressure of air aspiration cavity 13, lubricant oil enters in the oil groove of the slide block cylindrical side in the slider bore of cylinder under the effect of pressure reduction, plays lubricated effect; When the pressure in the vane hole 12 is higher than the pressure of compression chamber 14, lubricant oil is because the effect of pressure reduction, enter in the oil groove of slide block cylindrical side in the slider bore of cylinder, and be stored in this oil groove, even when the pressure in the vane hole 12 is lower than the pressure of compression chamber 14, the lubricant oil that is stored in the oil groove also can play lubricated effect, thereby improves lubricating between slide block cylindrical and the slider bore inwall, improve compressor reliability, and this oil groove holds the bits effect in addition.
