Definitions

  • This invention relates to aftercoolers for use between the compressor and the reservoir in an air supply line; which aftercooler cools the air from the compressor and filters out the water and other contaminats, which it then automatically ejects.
  • a new hot air circulating means comprising a plate having a plurality of holes communicating with the space between the bore of the body and the baffle. Further, the bore has been redesigned and tapered inwardly from its upstream end toward its center and then outwardly from the center toward the downstream end, so as to create a Venturi effect on the air flowing in the space between the bore and the baffle.
  • FIG. 1 is a top view of an aftercooler in accordance with the preferred embodiment of our invention.
  • FIG. 2 is a section taken as indicated by lines and arrows 2-2 in FIG. 1;
  • FIG. 3 is a slightly enlarged section partially broken away of a portion of the aftercooler taken as indicated by the lines and arrows 33 in FIG 2.
  • FIG. 2 We have redesigned the bottom header designated generally 10 (FIG. 2) to provide a funnel shaped unobstructed cavity 12 for accumulating the hot condensate and contaminants. Air enters this. funnel shaped por' tion 12 through the oval shaped entrance port 16 shown in the cut-away view FIG. 3. This oval shaped port defines the entrance of the passage 18 which is in fluid flow communication with the conduit 20, connected by any suitable means to the compressor (not shown).
  • a second passage 22 is provided. passing horizontally through the header 10 and having a plurality of shoulders and threaded portions therein.
  • This passage houses the condensate discharge valve mechanism which is clearly illustrated and which corresponds to the valve mechanism shown in FIGS. 2 and 3 of US. Pat. No. 3,516,231.
  • This passage 22 is connected by any suitable means to a conduit 24 which is connected to a governor (not shown) and transmits air input sig- Positioning the valve mechanism in the header provides for'through heat communication between the incoming hot compressed air and the valve, through a wall integrally formed in the header in direct heat transfer relation to the cavity 12 and the passage 18. Only the thin wall separates the chamber 12 from the passage 22 and this wall conducts and distributes the heat to prevent the valve from freezing. Furthermore, the valve is always positioned correctly as is the discharge pipe 34, thereby eliminating mistakes in maintenance due to unfamiliarity with the equipment.
  • the hot air coming into the chamber 12 passes upwardly about the cylindrical baffle 36 as is well known in the art and dissipates its heat through the surface forming the bore 14 and the outer fins 38.
  • a plate: 40 which is annular and which has a plurality of holes 42 therein communicated with the inner chamber of the baffle 36.
  • a bolt 44 is attached through the baffle and'is threaded into a hole in the center of the plate40.
  • a spacer 46 on bolt 44 inside the baffle holds the baffle and the plate at a controlled distance. This arrangement eliminates the need for the boss shown in the prior U.S. Pat. No. 3,516,231.
  • the walls of the bore 14 are tapered inwardly from the plate toward the longitudinal center of the bore designated generally C in FIG. 2. From this center the walls taper outwardly to the upper end 50. This tapering effect provides a function similar to that of the Venturi and aids in heat dissipation and fluid movement.
  • This device has been further modified from that shown in the prior art patent by the provision of the new top header designated generally 60 which has a centrally located outlet port 62 communicating with an enlarged chamber 64 wherein there is mounted a check valve 66.
  • the chamber 64 communicates with a passage 68 in a cap 70.
  • the cap 70 has a conduit 72 threaded therein in fluid communication with the passage 68, which conduit leads to the supply tank reservoir of the fluid system.
  • the movable valve member 66 closes on the usual conical valve seat shown, which is formed in the walls of the cavity 64. Cooking of the valve is eliminated by the vertical mounting and the guide ribs 80 which are in contact with the walls of the cavity, and consequently, the valve wears and seats uniformly.
  • the spring 82 urges the movable chamber toward the seat, so that the valve functions to permit the discharge of air from the housing, but prevent its return.
  • the header 60 also has a pasage 74 therein communicating with a conduit 76 which in turn communicates with a safety valve (not shown, but well known in the art).
  • An aftercooler for cooling and cleaning compressed air comprising: a housing having an inlet and an outlet and means therebetween for cooling air passing from the inlet through the outlet; and a headerjuxtaposed to the inlet comprising a body defining a cavity therein communicating with the inlet having a port therein communicating with a passage through said header to permit fluid flow communication with a source of compressed air; said header having a second passage therein containing discharge valve means to permit the discharge of fluid from said second passage; said header having a port communicating with said second passage from said cavity to permit the flow of liquid from said cavity into said second passage through said port; said valve means being completely disposed within the body of said header and being separated from said first mentioned passage by a wall integrally formed in said header in direct heat transfer relation to said first passage and said cavity in sufficient proximity to said first mentioned passage to prevent freezing of said fluid on the surfaces of said valve means.
  • said housing contains a cylindrical baffle disposed in spaced relation to the inner walls of said housing which form a bore; and said perforations in said plate are annularly disposed to permit fluid flow communication between said cavity and the space between said baffle and the walls forming said bore.
  • a second header is juxtaposed to the outlet of said housing; said second header having a chamber therein and a check valve means within said chamber for permitting air to pass from said outlet and preventing its return.
  • check valve means comprises a seat formed in said cavity and a movable member having a plurality of guide means thereon engaging the walls forming said cavity, to guide said movable member toward and away from said seat.
  • An aftercooler for cooling and cleaning compressed air comprising: a housing having an inlet and an outlet and means therebetween for cooling air passing from the inlet through the outlet; and a header juxtaposed to the inlet comprising a body defining a cavity therein communicating with the inlet having a port therein communicating with a passage through said header to permit fluid flow communication with a source of compressed air; said header having a second passage therein containing discharge valve means to permit the discharge of fluid from said second passage; said header having a port communicating with said second passage from said cavity'to permit the flow of liquid from said cavity into said second passage through said port; said valve means being completely disposed within the body of said header and being separated from said first mentioned passage by a wall integrally formed in said header in direct heat transfer relation to said first passage and said cavity; said housing having a cylindrical baffle disposed within said housing in spaced relation to the walls of said housing which form a bore; and said walls are sloped inwardly from the inlet toward the longitudinal center of said bore and then outwardly toward the outlet of
