Abstract: The valve system, to be used as a suction valve and/or as a discharge valve in a reciprocating compressor, comprises a valve body, at least one sensor mounted on the valve body and configured to detect a parameter associated to operation of the valve device, and a wireless communication unit electrically coupled to the at least one sensor and configured to transmit information detected by the at least one sensor; the at least one sensor is associated with a fixing member that is inserted in holes of the valve body and that seals the holes. The innovative valve system may comprise further at least one energy harvesting system, which could be for example thermoelectric or piezoelectric, located preferably in or on or at the valve body.

Abstract: A manufacturing method for manufacturing a cylinder for a reciprocating compressor is disclosed. The method comprises the step of manufacturing a compressor barrel comprising a cylinder chamber, a first suction valve seat, fluidly coupled to the cylinder chamber through a respective first gas suction port; and a first delivery valve seat, fluidly coupled to the cylinder chamber through a respective first gas delivery port. The method further comprises the step of manufacturing a gas inlet plenum and further manufacturing a gas discharge plenum, separately from the compressor barrel.
