...Technical Information Fittings General points Fittings are available in different versions. It must be noted that connection muffs for flexible refrigerant pipelines have certain structural features at one end. • A cylindrical straight connection pipe, the outer diameter of which m...

...Pressure Switches - General Pressure switches serve to protect the air conditioning from damage resulting from excessively high or low pressures. Different types are: low pressure switches, high pressure switches and trinary switches. Trinary switch es contain the high and low pressu...

...Working with Refrigerants - Safety goggles and gloves must always be worn! At normal atmospheric pressure and normal ambient temperature liquid refrigerant can vaporise very suddenly, that if it comes in contact with the eyes or skin, frostbite can occur (risk of loss of sight). - If...

...Technical Information Tube connector (Vulkan-Lokring) Again and again, tubes and connections become damaged due to vibration or on account of non-professional routing. Usually these tubes are replaced by new ones. It is not absolutely necessary to fall back on original tubes which ar...

...Universal pressure switch set General This pressure switch set is specially constructed for universal fitting to all systems (pressure switch connections with an outside thread 3/8”- 24UNF or ¼”) . The switch points are 2,1 / 17,5 / 24 bar. Contents of the pressure swi...

...Technical Information Air Flow Sensor (MAF) General The air flow sensor records the incoming air flow. It is constructed of a duct style housing with a flow rectifier, sensor protection and a sensor module. The air flow sensor is fitted into the inlet pipe between the air filte...

...Technical Information Coolant temperature sensor General The coolant temperature sensor provides information for air/fuel mixture preparation by recording the operating temperature of the engine. The ECU adapts the injection time and the ignition angle to the operating conditi...

...Technical Information Crankshaft Sensor General Crankshaft sensors record the engine speed and crankshaft position. The fitting position is near the flywheel ring gear. More they are found on the engine block with the sensor ring bolted onto the crankshaft There are two differen...

...Technical Information Idle speed control valve General The idle speed control valve is bypass valve. Example, as shown, is for Opel. It is made of a cast housing with a magnetic valve servo unit. A jet stem is fitted to the servo unit. Through the movement of the servo unit th...

...Technical Information Injectors General Injectors have the task, during all driving conditions, to inject the correct amount of fuel calculated by the ECU. For good fuel atomisation and small condensation loss an engine specific distance to the inlet valve and injection angle a...
