Definitions
- the invention relates to a diaphragm valve, which in particular as a vent valve for the crankcase of an internal combustion engine is suitable, with a spring supported membrane, according to the preamble of claim 1.
- diaphragm valves type described are z. B. known from DE 44 13 322 C2. These valves consist of a housing, in which a membrane is usually installed in the housing division is. This works together with a suction line, whereby a closure of the valve is generated by a sufficiently large negative pressure in the suction line. The Membrane pressed onto the front end of the suction line, creating a closure comes about.
- a coil spring is used to set the switching vacuum, which supports the membrane and keeps it at a defined distance from the suction line.
- a heating device is installed in the diaphragm valve, which with the spring is in direct contact.
- the heater will not only the gas flowing through it heats up, but also the spring itself Store heat, which on the one hand the surface to give off the heat to the flowing gas is enlarged and on the other hand this component, which determines the function for the valve, cannot freeze. So that is also in transit Fluids at risk of icing ensure that the valve functions at all times. By In this way the heat introduced is optimal as protection against icing used.
- a special embodiment of the invention provides that the heating device on the one hand consists of a wall lining and on the other hand consists of a heating element.
- the Wall lining must be made of a good heat-conductive material. Suitable for this metals, especially copper.
- the heat is generated in the heating element, and transferred to the wall lining due to the direct contact.
- the heating element can be a PTC thermistor element, for example, which is used at low temperatures recorded a sudden increase in electrical conductivity. At deep As a result, the heater heats up automatically. At high temperatures, the circuit for operating the heating element is due its high electrical resistance is actually interrupted.
- a resistance heating element can be used. This must be supplied with electricity for heating depending on the temperature.
- the spring can also be in direct Contact the heating element. This is a particularly rapid heat transfer possible on the spring, which reduces the response times.
- the wall lining tubular and in the suction line accommodate.
- the flowing fluid passes through the suction line and becomes simultaneously warmed up.
- the spring to be heated is located near the suction line, whereby a direct heat transfer in the sense of the invention in a simple manner can be realized.
- a particularly inexpensive diaphragm valve results when the components of the heating device are cast into the housing.
- the housing material itself must be an electrical insulator his.
- the housing can e.g. B. be made of plastic, the manufacturing process can be realized particularly easily by pouring.
- FIG. 1 shows a crankcase ventilation valve 10 which is connected to an intake tract 11 of an internal combustion engine 12 is arranged.
- a return line 14 leads from the crankcase of the internal combustion engine to Crankcase ventilation valve 10.
- the intake tract 11 also contains an air filter 15 and an intake port 16, the intake combustion air through a Arrow is indicated.
- crankcase ventilation valve 10 The structure of the crankcase ventilation valve 10 is shown in Figure 2.
- the valve is formed by a housing 17 which has a cover 18.
- a membrane 19 In the housing division, which is formed by the cover 18, a membrane 19 is clamped.
- the Membrane is supported by a spring 20, which on the other hand is supported in the bottom of the housing.
- crankcase gas flows according to the one indicated Arrows through an inlet 21 into the interior of the housing 17 and on a sealing surface 22 of the membrane 19 past through a suction line 23 out of the housing.
- the introduction and the suction line have hose connectors 24, with the help of which they connected to the duct system for the passage of the crankcase gases can.
- the suction line 23 has a wall lining 25 which is formed by a copper tube becomes. This wall lining also forms a valve seat 26 for the sealing surface 22 the membrane. If the negative pressure in the suction line becomes too large, the sealing surface 22 pressed against the force exerted by the spring 20 on the valve seat 26, whereby the valve closes. To this function even at low temperatures to ensure perfect, the spring 20 is based on a paragraph 27 of Wall lining 25 from. As soon as the wall lining is heated by a heating element 28 is thereby also counteracts icing of the spring 20. This enlarges heat transfer to the flowing fluid, so does the valve seat is even more protected against icing.
- the wall lining 25 and the heating element 28, which is formed by a PTC thermistor is, together with plug contacts 29 in the housing 17 of the diaphragm valve cast. This results in an inexpensive component to be manufactured.
- the plug contacts run out of an outlet 30 which is used to hold a plug for the Power supply is suitable.
- FIG. Paragraph 27 is formed in this embodiment by the heating element 28, which Wall lining 25 surrounds in a ring. This is a particularly fast response time the spring ensures that the heating element is switched on.
