1. A reciprocating compressor comprising:
at least one functional assembly integrated by at least one compression cylinder and at least one reciprocating piston;
at least one electric motor capable of moving the reciprocating piston inside the compression cylinder;
at least one set of valves capable of controlling the flow of fluid entering and leaving the compression cylinder; said set of valves being arranged in a head of the reciprocating compressor;
at least one head cover (1) capable of being arranged next to the head of the reciprocating compressor;
at least one suction acoustic filter (3) integrated by at least one outlet pipe (4) provided with at least one outlet path (41) capable of being arranged next to the head of the reciprocating compressor;
said suction acoustic filter (3) being fastened to the head cover (1) using a fastener (6); said reciprocating compressor being characterized in that:
the head cover (1) comprises a housing space (2) adapted to accommodate, at least partially, the at least one outlet pipe (4) of the suction acoustic filter (3), the housing space (2) being defined and delimited by edge segments (21) of the head cover (1) and a wall segment (22) of the head cover (1), the said wall segment (22) being integral by at least one rib (23) facing into the housing space (2) of the head cover (1);
the suction acoustic filter (3) comprises an interface wall (5) arranged in at least a section of a lateral contour of the outlet pipe (4), said interface wall (5) being provided with at least one rib (51) facing in the opposite direction of the outlet path (41);
the fastener (6) comprises a deformable metallic element, with a contour analogous to a contour of the housing space (2) of the head cover (1);
the at least one rib (23) of the wall segment (22) of the head cover (1), and the at least one rib (51) of the interface wall (5) of the outlet pipe (4) of the suction acoustic filter (3), are complementarily aligned;
the fastener (6) is arranged between the at least one rib (23) of the wall segment (22) of the head cover (1) and the at least one rib (51) of the interface wall (5) of the at least one outlet pipe (4) of the suction acoustic filter (3), in order to be deformed when the at least one outlet pipe (4) of the suction acoustic filter (3) is juxtaposed to the housing space (2) of the head cover (1).
