Preferably, the cross section of this step sealing surface is trapezoidal, semicircle, rectangle, triangle or oval shape.
The utility model also provides a kind of compressor, and its characteristics are that it comprises as above-mentioned sealed type connection set.
Preferably, this compressor is a two-way tilted-plate compressor.
Positive progressive effect of the present utility model is:
Sealed type connection set of the present utility model and comprise its compressor, be provided with the step sealing surface by the end face at end cap, reduced the area of contact of the end face of bolt end face and end cap, make that the applying of end face of bolt end face and end cap is tightr, realize the sealing between the end face of bolt end face and end cap.Have the leakage, the sealing effect that prevent between the two very superior, reduce production costs and advantages of simple structure and simple.
