The degree of depth of described trapped fuel groove is H, and the thickness of central diaphragm is T, and H＜T/2 is arranged.
The internal diameter of described upper cylinder is d, and the external diameter of central diaphragm is D, and the distance between the center of trapped fuel groove and the inwall of upper cylinder is L, the length of trapped fuel groove is K, (K/2)+R＜L＜((D-d-K)/2)+R is then arranged, wherein, R is correction factor, and R is 1～3 millimeter.
The width of described trapped fuel groove is W1, and the vane slot width is A, and W1＜A is then arranged; The trapped fuel groove is positioned at the vane slot scope, the center line of trapped fuel groove and the coaxial setting of the center line of vane slot.
The width of described trapped fuel groove is W2, and the width of vane slot is A, and W2=A is then arranged; The exhaust side of the center line deflection vane slot of trapped fuel groove.
The width of described trapped fuel groove is W3, and the width of vane slot is A, and W3＞A is then arranged; The center line of trapped fuel groove and the coaxial setting of the center line of vane slot, the trapped fuel groove is across vane slot.
The utility model is provided with for the trapped fuel groove of storing lubricant oil by the end face at central diaphragm, this trapped fuel groove is communicated with vane slot, when compressor operating, this trapped fuel groove helps the oil film between the end face of the upper and lower end face of slide plate and central diaphragm to form, thereby improve lubrication effect, reduce the abrasion between the end face of slide plate and central diaphragm, promote the service behaviour of compressor.
The utility model had both gone for twin-tub rotation-type compressor, also went for multi-cylinder rotary compressor, its have simple and reasonable, reliability is high, effectively reduce the compressor abrasion, performance boost, characteristics applied widely.
