Definitions

  • the present invention relates to a lubricating system for rotary piston compressors in which the lubricating oil passes from a storage container in predetermined quantities to the lubricating points.
  • a lubricating system for rotary piston compressors in which the lubricating oil passes from a storage container in predetermined quantities to the lubricating points.
  • the piston pump must have a plurality of pistons and a multi-stage transmission with regard to the speed of the shaft of the rotary piston compressor which requires a greater number of parts and is expensive.
  • Drip oilers and wicks are reliable onlywhen the ambient temperature does not vary much, because otherwise the quantities of lubricating oil will, due to the change in viscosity, likewise change.
  • the problem underlying the present invention consists in providing a structurally simple lubricating system according to which very small predetermined quantities of lubricating oil can from a storage container be conveyed uniformly to one or more lubricating points while different temperatures of the lubricating oil will have no influence upon the efficiency of the lubrication, and only a minimum of movable parts will be necessary.
  • the lubricant to a rotating splash disc connected to the shaft of the rotary piston conveyor. From said splash disc the centrifuged-off lubricating oil passes to a minor portion to wires arranged within the range of effectiveness of the splash disc, said wires being arranged so as to decline with regard to the horizontal plane while leading to the lubricating points.
  • the opening from the compression chamber to the diaphragm piston pump is preferably located in a lateral portion of the rotary piston compressor.
  • the splash disc is connected to a counterweight on the shaft of the rotary piston compressor and the counterweight or a portion thereof serves as splash disc.
  • the wires provided within the range of efficiency of the splash disc are arranged, more or less far in radial direction with regard to the axis of rotation of the splash disc or the crosssectionally rounded wires have different diameters.
  • the timewise consumption of lubricating oil at each lubricating point can be selected at random due to the fact that the wires are variously spaced from the splash disc or are of different diameters. Moreover, any desired number of lubricating points may be supplied simultaneously.
  • FIG. 1 The arrangement shown in FIG. 1 comprises a mantle 1, piston 2 with piston teeth 3, a shaft 4 with a shaft bearing 5, and a counterweight 6, an eccentric 7 of shaft 4 with eccentric bearing 8, a pinion 9 with teeth, and a side part 10.
  • Side part 10 together with an axially extending wall 11 and a cover 12 defines a closed chamber 13.
  • the arrangement according to the invention furthermore comprises a compression chamber 14 and a storage container 15 with the lubricating oil 16.
  • the position of theopening 17 in the side part 10 is so selected that during a major portion of the compression interval in the course of one revolution of shaft 4, this opening 17 communicates with the compression chamber 14 and is then briefly passed over by the sealing (not illustrated) strip springs of the piston.
  • the thus occurring pressure pulses in the opening 17 are conveyed to the diaphragms of the diaphragm piston pump 18 located in the chamber 13, and thus take care of the operation of said diaphragm piston pump 18.
  • the opening 17 may likewise be provided in the mantle 1.
  • the arrangement according to the invention furthermore comprises a suction pipe 19 and a pressure pump 20 associated with the diaphragm piston pump 18.
  • the pressure pump 20 laterally ends in a sleeve 21 closed at one end.
  • a pressure spring 22 causes a felt piece 23 to engage the splash disc 24 which latter is fixedly connected to shaft 4 and/or the counterweight 6.
  • the wire 25 located in the radial plane of the splash disc 24 and in the chamber 13 is inclined toward the side part 10 to which it is connected.
  • a bore 26 is provided in the side part 10 and leads at a decline downwardly to the lubricating point 27 which in this instance is identical to the teeth 9 of the pinion. From here the piston teeth 3 simultaneously receive lubricating oil.
  • the connecting area of the wire 25 and the entry to the bore 26 are in communication with each other through an inclined recess.
  • bores 28 and 29 located one above the other.
  • the operation of the lubricating system is as follows: In the compression chamber 14, the pressure will, due to the compression and intake operations, alternate with each revolution of the shaft 4. This alternating pressure is conveyed through opening 17 to the diaphragm of the diaphragm piston pump 18 so that lubricating oil is drawn in from the supply container 15 through the suction pipe 19, and through the pressure pipe 20 is drawn into the sleeve 21 and thus pressed into the felt member 23, which latter releases lubricating oil to the rotating splash disc 24. Due to the effect of centrifugal force, the lubricating oil is drawn off in finest droplets from the rim of the splash disc 24.
  • the lubricating oil particles trickle downwardly along the wires 25 in view of the force of gravity and are passed either through the bores 26 alone which are likewise inclined relative to the horizontal plane to the lubricating points 27 or the lubricating particles pass through the above mentioned bores 26 and non-illustrated tubes to the lubricating points 27 which may be located, for instance, at the other end of the engine.
  • cam linkage systems or gears usually liable to disorders are not required for the arrangement according to the invention.
  • main housing means main housing means, lateral housing means adjacent and laterally connected to said main housing means, rotary piston means rotatable within said main housing means and with said main housing means and said lateral housing means defining a compression chamber, a reservoir for receiving and storing a lubricant, a diaphragm piston pump arranged in said lateral housing means, first conduit means establishing communication between said reservoir and said diaphragm piston pump, second conduit means leading from said compression chamber to said diaphragm piston pump, bearing means arranged within said lateral housing means, shaft means rotatably journalled in said bearing means and eccentrically connected to said rotary piston means, splash disc means fixedly and eccentrically connected to said rotary piston means and rotatable therewith, said diaphragm piston pump being operable to draw a lubricant from said reservoir and convey iubricant to said splash disc means, and wire means arranged within the sphere of action of said splash-disc means and while being inclined relative to a horizontal plane leading to
