Cylinder cover for alternative compressor
A cylinder cover comprises a block ( 1 ) provided with at least a sealing contour ( 11 ) and at least a support projection ( 3 ) for supporting a discharge valve stop. The support projection ( 3 ) is spaced from the sealing contour ( 11 ) through at least one gap ( 4 ).
1. A cylinder cover for a compressor, comprising:
a block provided with a sealing contour;
at least one support extension defined in the sealing contour;
at least one support projection with at least a portion of the at least one support projection spaced from all sides of an inner perimeter of the sealing contour through at least one gap, wherein the at least one support projection is vertically parallel to at least a portion of the inner perimeter of the sealing contour;
the at least one support projection extending from a lower plate of the block;
the at least one support projection supporting a valve stopper;
the at least one support projection possessing mechanical resilience;
wherein the at least one support projection, during maximum mechanical deformation of the at least one support projection, remains spaced from the sealing contour through the at least one gap;
wherein the at least one support projection is contained between one side of the inner perimeter of the sealing contour and the at least one support extension defined in the sealing contour;
wherein the at least one support projection defines at least one flat top column supporting an edge of the valve stopper,
wherein the valve stopper includes a V-shaped plate including two integrated legs connected at a vertex of the V-shaped plate; and
wherein the at least one support projection extends to a same level as the sealing contour.
2. The cylinder cover, according to claim 1 , wherein the at least one support projection includes two support projections spaced from all sides of the inner perimeter of the sealing contour through the at least one gap and spaced from each other through another gap.
3. The cylinder cover, according to claim 1 , wherein the separation of the at least one support projection from the sealing contour through the at least one gap reduces the transmission of stress to other joint regions, the other joint regions being subjected to a lower physical deformation.
