For those of ordinary skill, above-mentioned term concrete meaning in the present invention can be understood as the case may be.
Below with reference to Fig. 1-Fig. 3, the compression mechanism for compressor 100 according to embodiments of the present invention is described.
As it is shown in figure 1, the compression mechanism for compressor 100 according to embodiments of the present invention, including two cylinders 21, song
23, two slide plate the 25, first springs 26 of axle and the second spring 27.
Specifically, being provided with median septum 22 between two cylinders 21, each cylinder 21 is provided with compression chamber 211, vane slot 212 and
Spring eye 213.As it is shown in figure 1, vane slot 212 and spring eye 213 extend along the radial direction of cylinder 21, the one of vane slot 212
End connects with compression chamber 211, and one end of spring eye 213 connects with vane slot, the other end and the ft connection of cylinder 21.
Bent axle 23 includes two eccentric parts 231, and two eccentric parts 231 are the circumferentially-spaced distribution of bent axle 23 and two partially
Angle between heart portion 231 is 180 °, and two eccentric parts 231 are respectively provided in two compression chambers 211, on each eccentric part 231
Being cased with outward piston 24, two slide plates 25 are the most reciprocally located in two vane slots 212.As it is shown in figure 1, two bias
Portion 231 is the most spaced apart, and becomes 180 degree of settings in the circumference of bent axle 23.
First spring 26 and the second spring 27 are respectively provided in two spring eyes 213, and one end of the first spring 26 is only against
Often to promote slide plate 25 to be only against on corresponding piston 24 corresponding compression chamber 211 is divided into high pressure chest on corresponding slide plate 25
And low pressure chamber, one end of the second spring 27 is only against on corresponding slide plate 25 often to promote slide plate 25 to be only against corresponding piston 24
On corresponding compression chamber 211 to be divided into high pressure chest and low pressure chamber, wherein coefficient of elasticity K1 of the first spring 26 be less than the second bullet
Coefficient of elasticity K2 of spring 27.
Due to, general sliding blade spring design relative resilient coefficient is relatively big, length is shorter, therefore, revolves especially for twin-tub
Rotary compressor, its bent axle has two eccentric parts, then need to install two sliding blade springs, owing to two eccentric parts are 180 ° of phases
To distribution, when installing second sliding blade spring, when turning crankshaft makes the decrement minimum of second sliding blade spring, then same
Time first sliding blade spring decrement be but maximum, now the spring force of first sliding blade spring is maximum, therefore first
Sliding blade spring installation difficulty, and have the biggest ejection risk.
