Embodiment Construction

[0033] A preferred embodiment of the present invention will be described below in conjunction with the accompanying drawings.

[0034] Fig. 3 is a schematic structural diagram of the two-stage compressor of the present invention, and Fig. 5 is a schematic diagram of its working principle. As shown in FIGS. 3-5 , the compressor is composed of first and second compression units 32 and 31 . The second / first compression unit is driven by the motor on its upper part, and the second / first compression unit and the motor are both placed inside the compressor housing. The first compression unit 32 is defined by the first cylinder head 3 , the first cylinder 9 , the first piston 11 , the middle plate 4 , the first blade 13 , the lower spring 15 and the air inlet 17 . The first piston 11 is placed eccentrically in the first cylinder 9, and the head of the first vane is in relative sliding contact with the surface of the first piston. In the working process, the first piston surface, th...

Abstract

The invention relates to two stage rolling rotor compressor. It includes intermediate plate, the first and second compressing unit. The intermediate plate is set through hole. The crankshaft is set the first and second de-centering parts. The first compressing unit contains compressing cavity and inspiration cavity. The second one contains the second stage compressing cavity and inspiration cavity. The compressing cavity of the first one is connected with the inspiration of the second one by the through hole of the intermediate plate to form the first stage compressing cavity together.

Description

technical field [0001] The invention relates to a two-stage rolling rotor compressor. Background technique [0002] PCT / JP92 / 01458 (WO93 / 10356) discloses a two-stage high back pressure rolling rotor compressor in the prior art, and its structural diagram is shown in Fig. 1 and Fig. 2 . The primary discharge cavity 126 of the compressor communicates with the secondary suction cavity formed in the second cylinder 121 through a channel. The flow direction of the gas is: with the rotation of the crankshaft 104, the gas entering the compressor is compressed by the first stage, then discharged from the exhaust hole on the first cylinder head 125 to the lower exhaust chamber 126, and then passes through the first cylinder head 125. The air hole 123 on the first cylinder 124 and the middle plate 122 enters the second-stage compression cavity in the second cylinder 121, and is discharged into the housing after the second-stage compression, and discharged from the compressor after co...
