Definitions

  • the invention relates to an air conditioning compressor for air conditioning systems in motor vehicles, the air compressor having at the high pressure outlet a check valve and a pressure limiting device.
  • Such compressors are known.
  • the integration of the check valve is required to improve the starting behavior of the stroke volume adjustable compressor and to ensure the clutchless drive of the compressor for the deactivated air conditioning operation.
  • This check valve is installed in the high pressure area of the system and separates at least in the case of a pressure gradient opposite to the passage direction of the check valve within the high pressure side, the high pressure side in two sections.
  • a pressure relief valve is integrated on the high pressure side in the air conditioning compressor, which lies downstream of the check valve. This means that in the case of a pressure gradient on the check valve counter to the passage direction of the check valve, so with a pressure increase in the remaining high pressure range of the air conditioner, the high pressure on the pressure relief valve can not be reduced.
  • an air conditioning compressor for air conditioning systems in motor vehicles, wherein the air compressor at the high pressure outlet has a check valve and a pressure limiting device, such as a pressure relief valve or rupture disc, wherein the pressure limiting device is arranged downstream of the check valve and parallel to the check valve arranged a Differenzdruckbegrenzungseinrich- device is.
  • An air-conditioning compressor is preferred in which the differential-pressure limiting device acts in both directions of flow, that is to say both in the direction of flow from the air conditioning compressor in the air conditioner as well as in the reverse flow direction. This has the advantage that even when using a check valve, a pressure limit for the entire high-pressure area of the air conditioning is ensured in front of and behind the check valve.
  • differential pressure-limiting device is a valve device that is reversible, reusable.
  • an air-conditioning compressor is preferred in which the differential pressure-limiting device is a rupture disk.
  • Another inventive air compressor is characterized in that the rupture disk is integrated in the check valve. Also, an air-conditioning compressor is preferred in which the pressure difference for the triggering of the rupture disk is greater than the pressure difference for the check valve. This has the advantage that initially an increase in pressure above the maximum pressure at the compressor outlet via the check valve can act on the pressure limiting valve arranged behind it. Only in the event of jamming or failure of the check valve will then trigger the differential pressure limiting and connect the increased pressure at the compressor output to the pressure relief valve in the other part of the high pressure line of the air conditioner.
  • a compressor is preferred in which the differential pressure limiting device on the high pressure side of the air conditioning unit connects the air conditioning compressor and the remaining high pressure part of the air conditioning system, ie both system parts, with the actual pressure limiting valve.
  • FIG. 1 shows schematically the high pressure area of an air conditioning system with an air conditioning compressor with a differential pressure limiting device.
  • FIG. 2 shows the high-pressure region of an air conditioning system with a differential pressure limiting valve.
  • FIG. 3 shows the high-pressure region of an air conditioning system with a rupture disk integrated in a check valve as a differential pressure limitation.
  • FIG. 1 shows the high-pressure region of an air-conditioning system including an air-conditioning compressor 1.
  • the air conditioning compressor 1 sucks refrigerant, compresses it and conveys it via a check valve 3 in an outlet 11, with which the outer high-pressure part of the air conditioner begins. From the outlet line 11, the refrigerant first flows through a gas cooler 5, then via an inner heat exchanger 7 and finally reaches the expansion valve 9, where the refrigerant expands to a lower pressure. Thus, the high pressure area of the air conditioner goes into the low pressure area, which is not considered here.
  • the compressor 1 has a housing 13 in which both the check valve 3 and a pressure limiting device 15 and a differential pressure limiting device 17 are arranged.
  • the check valve 3 is required to improve the starting performance of the stroke volume-adjustable compressor 1 and to ensure the clutchless drive of the compressor 1 for the shut-off air compressor operation.
  • the check valve 3 which may have, for example, an opening pressure of 2 bar, builds up directly at the start of a certain pressure in the compressor 1, which ensures a swinging of the compressor engine and thus for a immediately beginning promotion of the air conditioning compressor 1.
  • Downstream of the check valve 3 is a pressure limiting device 15, for example in the form of a pressure limiting valve or a rupture disc, arranged which opens, for example, when a maximum pressure of about 160 bar is exceeded and prevents further pressure increase.
  • This pressure limiting device 15 thus secures via the check valve 3 both the maximum pressure of the compressor 1 and the remaining high-pressure part of the air conditioning system up to the expansion valve 9.
  • a differential pressure limiting device 17 can be operative which, for example, connects the air conditioning compressor 1 and the remaining high pressure area of the air conditioning system at a differential pressure of 10 bar in both directions.
  • such a differential pressure limiting device is shown schematically as a differential pressure valve.
  • Parallel to the check valve 3, an effective in the same flow direction check valve 19 and an effective in the opposite direction check valve 21 are arranged.
  • the valves 19 and 21, for example, each have an opening pressure of 10 bar, so that at a pressure difference between the air conditioning compressor and the other high pressure area 23 of the air conditioner both parts of the system at a pressure difference of 10 bar with each other and thus connected to the pressure relief valve 15.
  • the opening pressure of the differential pressure limiting device for example, 10 bar, higher than the differential pressure of the check valve 3, as this normally fulfills the safety function with the pressure relief valve 15 arranged behind both for the compressor 1 and for the high pressure area 23 of the air conditioner.
  • the piston 31 of the check valve 29 is pressed within the valve housing 33 by a coil spring 35 in the valve seat 37, wherein the coil spring 35 with a biasing force up to an opening pressure of about 2 bar, the valve 29 is closed.
  • the refrigerant from the compressor 1 via the line 39 to the output line 11 of the air compressor in the high-pressure region 23 of the air conditioning can be passed.
  • the rupture disk 25 will break and thus the line 41 between the air conditioning compressor 1 and the high-pressure region 23 of the air conditioner will be effective.
