Definitions
- Fail-safe turntable for a coolant circuit to avoid damage to an internal combustion engine due to insufficient cooling capacity in case of failure of the turntable.
- Such fail-safe turntable are preferably used to provide an emergency operation of the coolant circuit of an internal combustion engine when the controlled by the turntable coolant due to a malfunction of the turntable is no longer sufficient for proper cooling of the engine.
- DE 102 43 778 A1 shows an adjusting device with an electromotive rotary drive, by which an adjusting element, in particular a rotary valve of a rotary valve, about a rotational axis between a first end position and a second end position is rotatably driven and acted upon by a spring from the first end position out.
- the electromotive rotary drive is designed as a reversing drive and the spring deflection of the adjusting element is effective only between the first end position and an intermediate position, the intermediate position lying between the first end position and the second end position.
- control element embodied as a rotary slide valve is a control valve in a coolant circuit of an internal combustion engine
- cooling of the internal combustion engine in emergency operation is maintained by the rotation of the actuating element resulting from the spring action of the control element in the event of failure of the electromotive rotary drive.
- a disadvantage of the adjusting device shown, however, is that the emergency operation is initiated immediately after failure of the rotary drive due to the constant presence of spring action of the actuating element.
- the cooling medium depending on the ambient temperature, engine load and driving speed, no longer heat up to the operating temperature, resulting in a loss of efficiency of the internal combustion engine during emergency operation results.
- the object of the present invention is therefore to provide a fail-safe turntable for a coolant circuit, which can initiate an emergency operation for the coolant circuit as required.
- a fail-safe turntable for a coolant circuit in particular for a multiple partial circuits having coolant circuit of an internal combustion engine, has a coolant pump for circulating the coolant within the coolant circuit, and a plurality of housing fürströmö réelleen exhibiting rotary valve housing in which at least one rotary valve with at least one rotary valve flow-through rotatably mounted is, wherein the housing flow openings are fluidly connected to at least one subcircuit and can be brought by a rotational movement of the rotary valve in at least partially overlapping with the rotary valve flow and wherein a thermostatic valve when exceeding a temperature limit of the coolant is guided parallel to the rotary valve flow path of a the partial circuits to the coolant supply pump opens.
- a temperature-dependent switchable thermostatic valve is arranged parallel to the rotary valve, in a failure of the rotary valve control an emergency operation can be ensured by the fact that the thermostatic valve for the coolant an alternative flow path tohariffenschför- the pump opens. Due to the temperature-dependent circuit of the thermostatic valve, this flow path is switched only when the temperature of the coolant has reached a critical for the operation of the internal combustion engine limit temperature. As a result, the engine is not prevented from reaching the operating temperature despite a malfunction of the turntable, which contributes to a reduction in fuel consumption and emissions.
- the turntable is very robust, since no components needed for emergency operation attack directly on the rotary valve, which allows easy movement of the rotary valve and low component wear. Also, the thermostatic valve has a very low wear, since it has to be operated very rarely.
- a radiator feed directs coolant from the engine to a heat exchanger and a radiator return directs the coolant exiting the heat exchanger to the rotary valve.
- the heated by the internal combustion engine coolant is passed through the radiator flow to the heat exchanger, in which it can cool.
- the exiting from the heat exchanger, cooled coolant is passed through the radiator return to the corresponding housing flow opening of the rotary valve.
- From the radiator flow can also branch off a bypass and direct heated coolant to another housing flow opening.
- the temperature of the coolant in the radiator feed is compared with the limit temperature of the coolant for switching the thermostatic valve.
- the temperature of the heated coolant in the radiator feed for comparison with the specific limit temperature. is pulled, can be responded to a critical increase in the coolant temperature of the internal coolant in the engine faster.
- the temperature measurement is independent of the currently achieved cooling rate of the downstream heat exchanger, which can vary considerably during operation.
- the thermostatic valve to a check valve which is mounted in a valve seat and is pressed by a spring sealingly against this, and arranged on the shut-off valve push rod which is actuated by an expansion element, which deals with the coolant of the radiator expands in conjunction with the expansion element when the coolant reaches its limit temperature and lifts the shut-off valve out of the valve seat against the pressure of the spring via the push rod.
- the thermostatic valve has an expansion element, preferably in the form of a wax capsule, which is in contact with the coolant from the radiator feed, compliance with the limit temperature can be monitored without additional electronics.
- the limit temperature is determined by the material properties of the wax used, which expands upon reaching the limit temperature and thus exerts a force on the push rod arranged thereon.
- the shut-off valve mounted at the other end of the push rod which is preferably designed as a poppet valve, is pressed by a spring sealingly against a complementary valve seat. When the expansion element now exerts a force on the push rod, the shut-off valve can lift off the valve seat, which opens a guided parallel to the rotary valve flow path.
- the thermostatic valve on both sides of the shut-off valve arranged and acted upon with coolant chambers, wherein a first chamber with coolant from the radiator return can be acted upon and a second chamber has a fluidic connection to the suction port of the coolant pump.
- the chambers are preferably designed as cages, so that the coolant as easily as possible can flow in and out.
- the first chamber is always filled with coolant from the radiator return, while the second chamber usually contains coolant from the rotary valve.
- a gap is formed between the rotary valve and the rotary valve housing, through which the coolant from the second chamber of the thermostatic valve can flow to the suction port of the coolant pump.
- the coolant can reach regardless of the current position of the rotary valve through the annular gap formed to the suction port of the coolant pump. Additional radial passage openings in the rotary valve can facilitate the passage of the coolant from the second chamber of the thermostatic valve in the rotary valve.
- the coolant delivery pump conveys the coolant sucked from the rotary valve into a heating circuit and / or an internal combustion engine intake.
- a heating heat exchanger and / or a heating feed pump and / or a Schuungsabsperrventil are arranged in the heating circuit.
- the heating conveyor pump is preferably operated electrically and can thus promote the coolant through the cooling circuit in addition to the coolant supply pump if necessary.
- the Schuungsabsperrventil can be closed when not required heating power, which causes a faster heating of the refrigerant in the other sub-circuits in normal operation.
- a further shut-off valve in particular a further rotary valve, is arranged in the internal combustion engine intake.
- a further shut-off valve in particular a further rotary valve, is arranged in the internal combustion engine intake.
- the coolant flow to the engine can be interrupted if necessary and selectively redirected into the heating circuit.
- the further shut-off valve is designed as a rotary valve, a rotational movement in dependence on each other can be carried out by a direct or indirect connection with the other rotary valve.
- the Schuungsabsperrventil when the limit temperature of the coolant is exceeded, the Schuungsabsperrventil is opened, so that the coolant from the coolant supply pump can be promoted via the heater core in the engine. This is particularly necessary if the designed as a rotary valve further shut-off valve in the engine inlet due to a malfunction can no longer pass coolant. In this case, it is necessary to direct a coolant flow from the rotary actuator via the heating circuit back into the internal combustion engine.
