Definitions

  • the invention relates to a refrigerator of the compressor-condenser-expander type, in which the inlet or lling stroke of the compressor piston is effected by the pressure of the refrigerating medium vapour, and the compression stroke of the compressor piston is eiected by an automatically cut-in auxiliary force.
  • a driving piston cooperates with the compressor piston in such manner that it follows the inlet stroke of the compressor piston and effects the compression stroke of the latter, the driving piston being moved by means of :liquid under pressure which s automatically controlled as desired.
  • a piston 2 serving for compressing the refrigerating medium
  • the cylinder I is connected by pipes3 and 4 to the upper end of an 'evaporator or expander and a condenser or liqueer, not shown.
  • Liquid refrigerating medium supplied is evaporated in the expander with absorption of heat, and liquefied in the condenser with emission of heat.
  • Expander and ⁇ condenser are connected together at the lower end by a pipe in which there is tted a throttle valve controlled by a oat or by temperature responsive means, not shown.
  • a springloaded inlet valve 5 and a spring-loaded outletl valve 6 are arranged in the upper end of the cylinder ⁇ I.
  • a pressure cylinder "I” Connected coaxially to the lower end of the compressorcylinder I is a pressure cylinder “I, in which is a driving piston 8 kept ata-distance from the compressorpiston 2 by means ofV a rod 9.
  • the driving piston 8 is constructed as a hollow cylinder which, on its downward movement, slides over a filling inset I0 provided in the-pressure cylinder l and which at the same time serves for limiting the downward stroke of the driving piston 8 and thus of the compressor piston 2.
  • a main pipe II leading from a storage container, not shown, of the drivingliquid is connected to the lower end of the pressure cylinder 1, and a gear pump I2 or other kind'of conveyor pump is connected in this pipe and'is adapted to be driven preferably by an electric motor.
  • the main pipe I I is also connected through a branch pipe I3, in which is iitted a non-return valve- I4".-*
  • a compression spring I1 acts, the tension of which is adjustable by means of a screw I8 which carries a plate I9 serv- To the pressure cylinder 'l there is connected, by means of an outflow pipe 20, a subsidiary cylinder 2
  • spring 2t is adjustable by means of a screw 25 which holds a plate 26 serving as an abutment for the spring 2li.
  • pressorl piston 2 .' is moved Adownwards under. the-A pressureeftect of thecooling medium .vapour owing from the. expander through the. pipe 3 into. the compressor cylinder I.
  • the double pistorr 22, 23 previously moved upwards inv thev an inserted regulator eiects a current interruption to the motor, and working ceases.
  • the Working cycle is again initiated when the temperature in a refrigerating cabinet tted with the compression refrigerating installation described rises, fory examplei'by--a prolonged opening thereof,f"to-say;41 ⁇ C., whereuponthe.te'mperature regulator referred to again throws in the electric motor so that the cycle of operations again commences.
  • A'Lthrottling device can be mounted in the return pipe 29 leaving the subsidiary cylinder 2 I, in order Ato permit the return i'lowfof the liquidunder pressuref'to thev storage container, and thusfto ⁇ regulate-the" falling; or-I inletfmovement of the rf compressor. piston 2.l
  • Refrigerating apparatus in which the piston in the subsidiary cylinder is a double headed piston, one of which heads of said double piston serves for controlling a connecting pipe provided between the subsidiary cylinder and the auxiliary cylinder and a check valve in the supply pipe of the auxiliary cylinder.
  • Refrigerating apparatus and in which the operating piston is provided ⁇ sith a peripheral groove for effecting connection of the return pipe of the pressure cylinder with the subsidiary cylinder so as to connect subsidiary cylinder with the liquid reservoir to allow dis charge of the subsidiary cylinder to the reservoir.
