Abstract

DC60 (12/12/44) The claim roll compactor consists of a trapped motor protection device. Set at a position away from the motor Such motor protection devices are characterized to It works to stop the motor both when the temperature in the coil compactor rises and when the electrical nature of the power supplied to the motor differs from the suitably specified. A motor protection device was integrated into the non-orbital coil element. In addition, the invention included a path to increase the sensing capability. Of such motor protection against various conditions That indicates the condition of the fan outside The building doesn't work In the themes, these paths consist of a tongue which opens to Send the hot output-pressure refrigerant to flow over the valve. On the other hand, that way is a heat sink that can work to bring heat away from the device. Motor protection In its final form, as the volumetric flow of the refrigerant decreases, the amount of heat that is removed is also reduced.
