At this point, the distance in cylinder head end face 203 of the spring face 106 away from compressor, i.e. spring through-hole z forward directions opening face is hmax；First
Meat thickness 302 and thick 303 the greater of the second meat are thick for the second meat, on the basis of spring face, the height in the z negative senses face of the second meat thickness 303
It spends for hmax-(h0+h2')；At this point, raised 101 end faces are more than the z negative senses face of the first meat thickness and second meat thickness the greater, that is, it is more than
The distance in the z negative senses face of the second meat thickness is h'=h- [hmax-(h0+h3')]；Therefore, when the slide plate of compressor 1 moves to z forward directions
During extreme position, protrusion 101 can be more than the z negative senses of the second meat thickness 303 from end face to the part between the section of end face h'
Face, in order to avoid protrusion 101 is interfered beyond the part in the second meat thickness 303z negative senses face with the second meat thickness, protrusion 101 is from end
Face should fall into spring through-hole to projection of the part on the spring through-hole radial section between the section of end face h'
In the range of, it is interfered to avoid 101 and second meat thickness 303 of protrusion.
In specific implementation, if when the slide plate 1 of compressor moves to z direct limit positions, the end face of protrusion 101 does not surpass
Cross the z negative senses face of the first meat thickness and second meat thickness the greater, i.e. h'<0, then the size and shape of the first protrusion can be arbitrarily devised,
Without departing from the cylinder sliding vane groove range of compressor.
