A cylinder cover comprises a block () provided with at least a sealing contour () and at least a support projection () for supporting a discharge valve stop. The support projection () is spaced from the sealing contour () through at least one gap ().

Cylinder cover for alternative compressor

The present invention refers to an acoustic filter for reciprocating compressor and, in special, a suction acoustic filter containing at least one inlet pipeline (), at least one outlet pipeline (), and at least one intermediate pipeline (). Said acoustic filter () comprises at least two horizontal chambers (), wherein said chambers are interconnected by an intermediate pipeline (), which has a superior portion () with a length that is equivalent to approximately 75% to 98% of the height of the first horizontal chamber () and an inferior portion () with a length that is equivalent to approximately 45% to 80% of the height of the second horizontal chamber ().

Acoustic filter suitable for reciprocating compressor

A refrigeration compressor is provided and may include a shell carrying a suction-inlet tube having an outlet nozzle opened to the interior of the shell and a cylinder block to which is mounted a suction muffler that incorporates an admission tube provided with an inlet nozzle. The inlet nozzle of the admission tube may be disposed adjacent to the outlet nozzle of the suction-inlet tube. The inlet nozzle may admit under at least one of the conditions of underpressure in its interior or deflection of the refrigerant-fluid flow in the interior of the shell the gaseous phase and may direct the liquid phase to a region of the shell external to the inlet nozzle.
