ABSTRACT:
The invention relates to a valve system for encapsulated motor-compressor units comprising a cylinder, a piston moving with reciprocating motion in the cylinder, a valve plate which upperly closes the cylinder, and a head fixed on to the valve plate, wherein in the valve plate there are provided two delivery ports having cross-sections of different size, so as to create in the lamina valve an asymmetric elastic deformation which favors gradual impact of the valve against the valve plate at the end of the compression cycle.
