Abstract: 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).

Abstract: A cylinder cover for alternative compressor 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. Said support projection (3) is spaced from the sealing contour (11) through at least one gap (4).

Abstract: The present invention relates to a connecting rod for reciprocating compressor, in particular a connecting rod converting the crank rotating motion into linear axial motion. The rod (1) having means capable of compensate efforts and ensure alignment and deflection of the piston (P) inside the cylinder (C). Such means comprising at least two regions (5, 6) capable of oriented resilient deformation, being such regions (5, 6) formed in the body (2) and oriented in opposite directions.

Abstract: The present invention refers to a compressor block (21), which has at least one passage opening of driving member (22), at least one frontal of support (24a) and at least one portion (26), so that at least one first and one second means of structural connection between the portion (26) and the frontal extensions of support (24a) are defined by at least one structural wall (28a) and at least one wall structure (28b). The structural walls (28a, 28b) define the main perimeter of the compressor block (21) and are provided with at least one section of physical association between each other.
