To achieve the above object, technical solution adopted in the utility model is：
A kind of swing-rotor compressor with end face seal structure, includes cylinder block, it is characterised in that：The cylinder
Body side surface is configured with seal face, and end face seal, which covers tightly, is affixed on the seal face setting, wherein, the seal face and end face
Being close to of closure it is provided with edge face sealing member between face.
Further, it is preferred that offering end face seal groove on the seal face, the edge face sealing member is embedded
In in end face seal groove.
Further, it is preferred that the edge face sealing member upper end exposes to end face seal groove；
Further, it is preferred that the edge face sealing member upper end is configured with the sealing lip radially extended in seal face
Piece.
Further, it is preferred that gap is left between the edge face sealing member bottom and seal groove, in the seal groove
The stomata of communication gap is offered, the stomata is communicated to cavity by the gas channels being opened in cylinder block.
By above technical scheme, compared with the existing technology, its advantage is as follows for the utility model：
1st, by setting edge face sealing member on cylinder block seal face, counterface closure is sealed, and is realized
High airtight stability, the pressure at expulsion for a long time under can be ensured, beneficial to the actual property for improving swing-rotor compressor
Energy and service life；
2nd, there is the characteristics of simple in construction, dependable performance, processing and manufacturing cost is relatively low, is suitable for large range promotion use.
