For those of ordinary skill, the specific meanings of the above terms in the present invention can be understood according to specific conditions.
The compression mechanism according to the ... of the embodiment of the present invention for compressor 100 is described below with reference to Fig. 1-Fig. 3.
As shown in Figure 1, the compression mechanism according to the ... of the embodiment of the present invention for compressor 100, including two cylinders 21, song
23, two slide plates 25 of axis, the first spring 26 and second spring 27.
Specifically, middle partition board 22 is equipped between two cylinders 21, each cylinder 21 is equipped with compression chamber 211,212 and of sliding vane groove
Spring eye 213.As shown in Figure 1, sliding vane groove 212 and spring eye 213 extend along the radial direction of cylinder 21, the one of sliding vane groove 212
End is connected to compression chamber 211, and one end of spring eye 213 is connected to sliding vane groove, and the other end is connected to the external of cylinder 21.
Bent axle 23 includes two eccentric parts 231, two eccentric parts 231 the circumferentially-spaced distribution of bent axle 23 and two partially
Angle between center portion 231 is 180 °, and two eccentric parts 231 are respectively provided in two compression chambers 211, on each eccentric part 231
It is cased with piston 24 outside, two slide plates 25 are reciprocally located at respectively in two sliding vane grooves 212.As shown in Figure 1, two bias
Portion 231 is spaced apart in the up-down direction, and is arranged at 180 degree in the circumferential direction of bent axle 23.
First spring 26 and second spring 27 are respectively provided in two spring eyes 213, and one end of the first spring 26 is only against
Often to push slide plate 25 to be only against on corresponding piston 24 dividing corresponding compression chamber 211 for high pressure chest on corresponding slide plate 25
And low pressure chamber, one end of second spring 27 are only against on corresponding slide plate 25 often to push slide plate 25 to be only against corresponding piston 24
On dividing corresponding compression chamber 211 for high pressure chest and low pressure chamber, wherein the coefficient of elasticity K1 of the first spring 26 be less than the second bullet
The coefficient of elasticity K2 of spring 27.
Since general sliding blade spring design relative resilient coefficient is larger, length is shorter, therefore, is revolved especially for twin-tub
Rotary compressor, bent axle tool then need to install two sliding blade springs, since two eccentric parts are 180 ° of phases there are two eccentric part
To distribution, when installing second sliding blade spring, when turning crankshaft makes the decrement minimum of second sliding blade spring, then together
When first sliding blade spring decrement be but the largest, the spring force of first sliding blade spring is maximum at this time, therefore first
Sliding blade spring is difficult to install, and has prodigious pop-up risk.
