    摘要: A gas compressor, such as a rotary vane one, for a refrigeration system is equipped with a supplementary inlet. By this gas in the liquid phase is injected into the compression chamber and reduces the temperature of the vaporized coolant gas as it is being compressed. This liquid gas is tapped from the normal refrigeration circuit. It can also be used, prior to injection, to cool oil circulated over the motor by a pump which the motor drives as well as the compressor.

    摘要: The invention relates to a hair styling appliance (100, 100′, 100″) comprising at least one heater (103, 104) having plurality of heating zones (Z1-Z5). The heating zones are independently operable arranged along the length of the heater. The sequential arrangement of the independently operable heating zones helps to improve the thermal control of the hair styling appliance. The hair styling appliance may be a hair straightener, curling tong, curling wand or a crimping iron.
