Definitions

  • the wall 7 is provided with a threaded bore 20, where a tube 21 is screwed-in,which, through a radial bore 21, brings the the said cavity 16 in communication with the inner side 22a of an air filter 22, this latter being located inside a box 23, supported by the wall 17; the said bore 21b is suited to allow the steams developping from oil contained inside the basement 16 to expand toward the inside 22a of filter 22, as to increase the filtering effect thereof and to lubricate the movable parts contained inside the equipment.
  • the first plate 24 has a central opening 30, where a ring--shaped element 31 is found, supported by three ribs 32a, 32b and 32C, integral to the plate 24 and suited to keep the said element 31 horizontal.
  • the first plate 24 has three concentric orders of ribs 28 degrading from outside toward inside and grooves 29, as well; the ribs of the first order face the grooves of the second order; the grooves of the first order face the ribs of the second order; the ribs of the second order face the grooves of the third order; the grooves of the second order face the ribs of the third order.
  • the two walls 18a and 18b separate, respectively, the said cavity 16 from two cylinders 37a and 37b, externally finned, as to get cooled during their operation, and internally open toward the cavity 16, in order to accomodate the end parts 8a and 8b, respectively, of piston 7.
  • the plate 39 (a,b) is concerned by the copend ing Patent Application Nr.
  • Each path ends into the corresponding cylinder.
  • a second path for compressed air starts from each cylinder.
  • the three slots face a cavity 57(a,b) existing inside the head 38(a,b),separated by the said cavity 47(a, b) from wall 48(a,b), central to the said head 38(a,b).
  • the said cavity 57 (a,b) communicates directly with a second cavity 58(a,b) machined from the same head 38 (a,b), where a pipe opens, that consists of two bores 59(a,b) and 60 (a, b) having the same diameter, and series connected one after another, which are machined, respectively, from gasket 41(a, b) and from plate 39 (a,b).
  • the bore 60(a,b) engages a tubular element 62(a,b), suited to convey the compressed air toward a delivery manifold 63, entered by the two pathes for compressed air, coming ,respec tively, from cylinders 37a and 37b.
  • the said tubular element 62(a,b) has an external profile 61(a,b), suited to enter a seat 70(a,b) foreseen inside the manifold 63,in order to fix both elements one to the other.
  • the manifold 63 is integral to a structure 64, that is fitted onto the basement 15 and makes up the front wall thereof.
  • the case 1 has longitudinal outer
  • a terminal strip 84,whe re the power supply cables of engine contained inside the case 1 end.
  • a seal ring 100a is foreseen on the said arm 97a (and, obviously, on arm 97b) in order to prevent air leakages from heads 38(a,b) toward the basement 15 during the compression phases of pistons 94(a,b).
  • Both pistons are provided with compression rings; Fig.4 shows the rings 101a, 102a and 103a only, relevant to the pi ston 94a, but it is understood, that as many compression rings, not shown, are provided to the piston 94b.
  • the last compression ring 103a is a scraper ring for scraping walls of cylinder 37a; it is understood, that an identical scraper ring, not shown, is provided to the piston 94b, for scraping walls of cylinder 37b.
  • the bushing 96 has an inner bore 104, suited to accomodate a piston pin 105, coaxial to the said bore 104 and to allow it sliding up and downwards along the said bore 104.
  • the said piston pin 105 has two countersinks 106 and 107, respectively below and above, and a horizontal bore 108, suited to accomodate a brass 109 of known type, in order to support the said pin 93.
  • the pin 93 describes a circular trajectory at steady speed rate with center placed on one point of axis A, and takes along the pin 105 in the same trajectory.
