PROPORTIONAL PRESSURE CONTROL VALVE COMPRISING A PRESSURE JUMP IN THE CHARACTERISTIC P/I CURVE THEREOF

摘要

oil injection compressor, in particular oil injection a screw compressor, with a motor-driven compressor unit (1) for the generation of compressed air, which with an oil circulating system (5) for the lubrication, which an oil separator means (6) for separating the oil is connected downstream from the compressed air, whereby in the area of the inlet of the oil-containing compressed air into the oil separator means (6) a self-resetting temperature switch (11) for switching off of the compressor unit (1) on reaching a maximum temperature limit of the inflowing air / oil mixture is provided, moreover, in the region of the oil separator means (6) at least one additional temperature switch (12) is provided which, as a result of a fire or of an explosion of the in the oil separator means (6) containing oil contained in the compressed air the compressor unit (1) is switched off immediately, characterized in that the additional temperature switch (12) is not - is self-resetting and that it is in the inner region of the oil separator means (6) are arranged, and that the triggering a pressing of verlöschungsstoffen in the inner region of the oil separator means (6) causes.
