Definitions

  • the compressor is of the type that incorporates two compression stages of identical compression ratio (twin single stage compression) or two cascaded compression stages (two stage compression).
  • the object of the invention is to make available a hydraulically operated, positive displacement, reciprocating compressor whose conformation is such as to limit, if not render nil, the buckling stress on the rods that control the pumping pistons, as well as to present, with respect to those known of the same capacity and compression ratio, a lesser number of heads, liners and pistons.
  • the chambers 12 and 13 communicate with corresponding ducts, 14 and 15, provided in the head 2 and terminating at hydraulic control means (not illustrated) destined to send oil under pressure alternately into the chamber 12 and into the chamber 13.
  • the chamber 17 (or first compression stage of the compressor) communicates with the outside via an intake valve 17a provided in the head 1.
  • the said head is also provided with a delivery valve 17b which, through a duct 18 (on which a device 19 exerts an action for cooling the compressed gas), terminates at the intake valve 16a (of the chamber 16) provided in the head 3. In the latter there is also a delivery valve 16b of the said chamber 16.
  • the cooling of the liners 4 and 5 is achieved in a way in itself known with provision being made for the said liners to have hollow spaces, 6 and 7, which, via the orifices 6a, 7a and 7b, terminate at a circuit (not illustrated since of a known type) for circulating water.
  • the breather rods 22 also have the task of equalizing, for two-stage compression, whenever oil is sent into the chambers 16 and 17, the thrust areas of the oil on the pistons 10 and 11, and this can be achieved by adjusting the.diameters of the two rods 22 so as to compensate for the differences in tne diameters of the liners 5 and 4.
  • the compressor additionally to the above mentioned advantage (namely that buckling stress on the rod 9 is practically inexistent), offers other advantages in consequence of the limited axial development and the reduced number of component parts compared with the compressors known to date of obviously the same compression ratio and volumetric capacity.
