Compressor for increasing volumetric efficiency of cylinder

Abstract

The invention discloses a compressor for increasing volumetric efficiency of a cylinder, which comprises a motor, a cylinder body assembly and an eccentric compression roller, wherein the cylinder body assembly comprises a cylinder as well as an upper flange and a lower flange arranged at two ends of the cylinder in a covering manner, the upper flange and the lower flange are respectively provided with an upper silencer and a lower silencer, a crank of the motor is provided with the eccentric compressor roller, the cylinder is internally provided with a slip sheet, the cylinder body assembly also comprises a partition plate arranged between two eccentric compression rollers of two cylinders when the compressor is a dual-cylinder compressor; the side wall of one of the upper flange, the lower flange or the partition plate of the dual-cylinder compressor is provided with an air inlet communicated with a cylinder working cavity, the side end face of the rotating eccentric compression roller is matched with the air inlet and a channel between the air inlet and the cylinder working cavity can be closed; and the air inlet is a semi-crescent closed maximum air inlet region formed by vertically projecting a slip sheet center line and a rotating trajectory of an excircle high point and an inner hole high point of the eccentric compression roller on the wall of the upper flange, or the lower flange or the partition plate, wherein the excircle high point and the inner hole high point of the eccentric compression roller support against the top end of the slip sheet center line.

Description

【Technical field】 [0001] The invention relates to the technical field of refrigeration compressors, in particular to a compressor for improving cylinder volume efficiency. 【Background technique】 [0002] Existing compressors at present, especially rotary air conditioner compressors, as shown in Figure 1, the compressor includes a cylinder 1, a flange, an eccentric compression roller 3, a crankshaft 4 and a sliding vane 5, and its suction structure is generally Air is supplied to the cylinder working chamber 1b through the intake hole 1a on the cylinder 1, mainly relying on the arc surface 3a on the top side of the eccentric compression roller to close the passage between the intake hole 1a and the compression chamber 1c, so the cylinder exhaust is completed Finally, when the high point 3b of the eccentric compression roller coincides with the groove center 5a of the slide plate 5, before the eccentric compression roller 3 closes the passage of the air intake hole 1a and the ...
