Definitions

  • ABSTRACT An air drying-moisture discharge tank system wherein the valve discharge means is integrally constructed with the tank.
  • the valve means comprises a pair of valves for collecting the moisture separated from the [52] US. Cl 165/71, 165/111, 137/590 pre rize flui stream applied to the tank and auto- [51] Int.

  • This invention relates to a fluid tank adapted to separate any contaminants including moisture from the pressurized fluid stream conveyed through the tank and means for automatically discharging the collected contaminants from the tank.
  • the present invention provides an improved and more efficient and more reliable tank capable of accepting a hot, moisture laden fluid stream and cooling it while separating out the moisture and contaminates contained in the fluid stream and automatically and periodically discharging the collected moisture from the fluid stream.
  • the tank includes an improved valve constructed integrally with the tank shell or housing for the tank for collecting and discharging the moisture separated from the air stream by the tank.
  • the integral construction of the valve with the tank is advantageously arranged to allow a heat exchanging operation to take place between the tank and the valve structure to heat the valve to render it inoperative over a wider range of temperatures without resorting to heating means than heretofor possible. For example, this will allow the tank-valve system of the present invention to be operative even in freezing temperatures that are not extreme freezing temperatures.
  • the integral valve structure is also more reliable due to the reduction in the amount of plumbing required since fewer ports and joints means fewer leaks.
  • the integral construction of the tank-valve system reduces the space envelope required on the motor vehicle.
  • the valve is also adapted to be automatically operated from two air sources. As applied to a truck having pneumatically operated brakes, for example, pressurized air that is employed for the brakes may function as one of the sources of the air for the automatic operation of the valve system so that pressurized air is applied to the valve for operating the valve with each operation of the air-operated service brakes by the truck operator.
  • the second source for such automatic operation of the valve to discharge the collected moisture and contaminants from the tank is the coupling of the valve to the governor/compressor system for the air brake system so as to render the valve automatically operable in response to the automatic cycling of the governor/compression system.
  • the valve per se is a diaphragm operated valve which has proven to be more reliable than an O-ring sealed piston element for responding to the air pressure applied thereto.
  • the diaphragm allows looser tolerance parts than the piston type construction thereby being less susceptible to binding and less susceptible to malfunction due to freezing small amounts of residual water.
  • the present invention comprehends a storage and collection tank for a pressurized fluid such as pressurized air and the like wherein the tank comprises an enclosed shell having an internal fluid passageway defined within the shell for conveying the fluid therethrough and constructed and defined to cause the heat of the fluid conveyed therethrough to be transferred to the shell and separating out any contaminates including any moisture in the fluid stream applied to the shell.
  • the tank includes means for conveying the pressurized fluid stream into the shell for conveyance to the internal fluid passageway and for conveying the pressurized fluid stream out of the shell. The contaminants including any moisture are separated from the fluid stream and are discharged to the bottom of the tank.
  • the tank includes means for collecting and discharging the separated contaminants from the tank arranged adjacent the fluid entry means or the hot side of the tank constructed and defined to be integral therewith.
  • the valve means employed for such a storage and collecting tank may comprise valve means mounted in a cavity at one end of the tank and having a movable plunger operated between an open position communicating with the interior of the tank and a closed position for sealing off the interior of the tank.
  • Conduit means are provided for communication between the bottom of the tank and the valve for conveying the collected moisture into the valve when the valve plunger has been moved into the open position so as to be discharged out of the tank when the valve is moved to a closed position.
  • the valve includes means for automatically operating the valve means between the open and closed positions periodically as a result of the vehicle operation and more particularly the pressurized air system for the vehicle.

  • the entry end bell 12 is provided with fluid conduit 15 extending between an entry port defined within the bell l2 and the liner 14 for conveying the hot, moisturized pressurized fluid stream as it may be received from the compressor of the air braking system with which the invention is employed.
  • the pressurized fluid stream will be conveyed around the internal surface of the shell 11 by means of the passageway defined between the shell 11 and the liner l4 and progresses longitudinally toward the exit bell 13 of the tank 10.
  • the heat of the fluid stream will be transferred to the outer shell wall 11 and any fins provided therefor to be radiated to the ambient air and thereby cools the stream as it travels towards the exit aperture 13A to the air-operated braking system.
  • the moisture is separated out and will be deposited at the bottom of the tank 10 and collected at that point.
  • F 1G. 1 the point of collection of the moisture and other contaminants, such as oil and the like, is defined as a sump 16. This is the general operation of the drying tank 10 of the aforementioned copending application and such structure forms no portion of the present invention.
  • the tank 10 is employed in a conventional air controlled braking system for a motor vehicle as disclosed in U.S. Pat. No. 3,515,438.
  • the tank 10 is incorporated into such a pressurized air source in accordance with the general air piping system illustrated in FlG. 1 of the aforementioned copending application, application bearing Ser. No. 182,291.
  • the cooled air stream exiting from the outlet 13A of the tank 10 is coupled to the air-operated braking system conventionally employed in trucks and trailers as described in said copending application.
  • trucks and trailers conventionally employ a service brake which the operator may render operative by the application of the pressurized air to the service brake for applying the brakes. This is effected by the motor vehicle operator by means of a foot-operated treadle arranged in the cab for his convenience; see US. Pat. No. 3,515,438.
  • the present invention incorporates into the end bell 12 of the tank 10 a valve structure for draining or discharging the water, contaminants, oil and the like that are collected in the sump 16 as a result of the application of the hot, moist, pressurized stream from the compressor to the tank 10 as it travels through the tank.

  • the two-way check valve 21 may be connected at one fluid port 28 to the piping associated with the service brake so that with the application of the pressurized air to the service brake by the motor vehicle operator, pressurized air will be also applied to the valve 218 to move the shuttle 29 to the left and allow the pressurized fluid air stream to be applied to the diaphragm 25.
  • the shuttle 29 is normally arranged in a sealing conduit 27 so as to place the primary valve 21P in its normally closed condition, as illustrated.
  • a further fluid port 30 is arranged on the opposite side of the valve 218 from the port 28 and it may be connected directly to the compressor/governor system so that with the normal cycling of the compressor system, pressurized fluid is applied to the port 30 to move the shuttle to the right and thereby seal off the foot brake signal 28 and apply the pressurized air stream to the diaphragm 25 for operating the primary valve 2lP.

  • valve means 21 of the present invention should be appreciated. Considering that the contaminants such as oil, water and the like have been collected at the sump 16 due to the air from the compressor being applied to the tank 10, it will be seen that with the closed position of the valve means 21, the collected materials will not be discharged from the tank and it is necessary in order to discharge the materials from the tank to operate the two-way check valve 21 to an open position either as a result of the operation of the service brake by the vehicle operator or through the cycling of the compressor/governor system.

  • the diaphragm 25 has flexed between its inner and outer edges that are secured to the end bell 12. With the loss of air pressure to the two-way valve 218, the pressurized air that flexed the diaphragm 25 will be removed from the diaphragm and it will move back to its closed position (as illustrated in FIG. 1) and away from engagement with the head of the plunger 23.
  • the materials that were collected in the chamber 20P will be drained through the drain port 26F and/or the drain tube 26D to the atmosphere and be discharged from the tank 10. This condition will prevail until a further signal is received at the two-way valve 215 for operating the primary valve 21P.

It will be recognized at this time that the drain 268 is sealed off as a result of the flexible diaphragm 25 being flexed into engagement with the bottom end of the plunger 23 between its inner and outer edges. This action will continue until the pressure builds up in the chamber 20? to balance the primary valve 21?. Subsequent release or venting of the air through the conduit 27 and the shuttle valve 218 will produce the complete closing of the valve 21P.

With the removal of the air from the diaphragm 25, the diaphragm 25 and thereby the plunger 23 will be moved back to its normal position as illustrated in FIG. 1. When this occurs, the materials that have been conveyed into the chamber 20? will be allowed to discharge around the plunger head 23H into the space now provided between the bottom end of the plunger 23 and the diaphragm 25 and out through the drain sleeve 238 and/or the tube 23D to the atmosphere, as illustrated.
