Title: Improvements relating to refrigerating machines
IPC: F25B1/04
Filed: 1924-02-29
Abstract: 217,178. Kucher, A. A. June 4, 1923, [Convention date]. Refrigerating, compression machines and processes for.-A mixture of lubricant and refrigerant inseparable by mechanical means, such as is described in Specifications 195,943 and 208,547 is employed, and the mixture discharged from the compressor is subjected to the heat of the compressor whereby the greater part of the refrigerant is vaporized, leaving a liquid consisting mainly of lubricant. This liquid is fed to the moving parts of the machine and is subsequently returned to the suction side, where it mixes with the refrigerant from the evaporator. The invention is described as applied to a machine comprising a rotary compressor 11 driven by an electric motor 12 and enclosed in a condenser casing 13, as described in Specification 187,604. The mixture is discharged from the compressor into an inner casing 18, from which vapour passes to the condenser chamber through an opening 44, while the liquid collects in the case of the chamber 18 and is fed through a pipe 54 to the top of the compressor. The compressor discharge pipe 41 carries a baffle plate 43, and excess of liquid in the casing 18 can overflow through an opening 45 into the condenser chamber, which is cooled by water flowing through pipe coils 46. The condensed refrigerant collects in the lower part of the condenser chamber and flows to the evaporators (not shown), through a pipe 47a fitted with an expansion valve 48 controlled by a float 49. The casing 13 is secured to the base casting 14 by bolts 15 and a ring 16, and is provided with charging openings for the lubricant and refrigerant and connections for the water coil. The electric leads 52 for the motor pass through screwed plugs 53 in the base. The motor and compressor shafts are connected by keys to permit separation, the armature of the motor being supported by a removable base casting 19. The lubricant flows past the upper bearing 26 and through the compressor parts to an intermediate bearing 25, from which it is free to flow through annular and radial passages 61, 62 to an axial passage 63 leading to the hollow motor shaft. Any oil leaking past the intermediate bearing falls on the flat end of the motor shaft and is thrown outwards into a catch tray 65 carried by the shaft. From the tray it passes into the hollow shaft through passages 67, 68. The lubricant collects in a well 71 in the base casting 19 and rises into an annular well 76. at a level below the centre of the ball bearing 72, being finally discharged through a pipe 77 connected with the return pipe 19 from the evaporators leading to suction passages 51, 29. In order to prevent the lubricant from being sprayed up into the motor, due to equalization of pressure when the machine is stopped, a check valve 80 is fitted in the pipe 77, and baffles 81, 82 and 84 are fitted in the casting 19 above the possible outlets for lubricant.
