Background technique
Twin-tub or multi-cylinder rotary compressor are in order to improve the exhaust velocity of cylinder compression chamber, it will usually in every two cylinder
Between be symmetrical arranged two middle partitions, it is each in an end face through-thickness of partition offer ring row air cavity, in discharge chamber
Accommodate exhaust valve.As depicted in figs. 1 and 2, exhaust valve includes exhaust valve plate and lift stopper 14 ', and the two is solid by rivet
It is scheduled on the valve seat in discharge chamber.Traditional lift stopper 14 ' is made of flat segments 142 ' and the bending section 144 ' upwarped, on
The bending section 144 ' stuck up is used to limit the maximum Lift of exhaust valve plate, when the maximum Lift of exhaust valve plate is larger,
The amplitude that the bending section 144 ' of lift stopper 14 ' upwarps is just very big, and the thickness of lift stopper 14 ' in flat segments 142 ' and
14 ' height of lift stopper almost unchanged on bending section 144 ' therefore traditional is larger, in order to accommodate so high lift limit
Device 14 ' needs the discharge chamber of middle partition to have enough depth, it is corresponding in the thickness of partition be also required to increase, partition in the middle
When thickness is larger, the length of interconnecting piece just needs to lengthen between two eccentric parts on compressor crank shaft, this undoubtedly will increase crankshaft
Axial length reduces the rigidity of crankshaft, so that the reliability of compressor reduces.In order to guarantee the reliability of compressor, usually adopt
The measure taken is the maximum Lift of reduction exhaust valve plate to reduce the thickness of partition, but the Lift of exhaust valve plate reduces
It will increase exhaust resistance, so that the efficiency of compressor reduces.
