The utility model relates to an automatic temperature adjustment valve assembly for a cooling cycle of an internal combustion engine. The automatic temperature adjustment valve assembly stabilizes the coolant temperature within a design scope of the internal combustion engine. The automatic temperature adjustment valve assembly is characterized in that holes on the valve surround a passage of a thermo-actuator for coolant to generate a coolant flow from engine block to a radiator.

Description
Technical field
The utility model relates to the automatic temperature-control assembly for the cooling recirculation system of internal-combustion engine, so that coolant temperature is stabilized in the internal combustion (IC) Engine Design scope.
Background technique
In having the internal-combustion engine of liquid coolant, by fuel combustion produce overheated by the freezing mixture transmission, circulate coolant is by the passage in cluster engine and the cylinder head.Like this, motor can move in suitable temperature range.Now, because the emission index that allows of various regulation reduced year by years, reducing from internal-combustion engine is one of maximum design consideration to total noxious gas emission of environment.In the state that moves under the different temperatures of motor outside the design temperature scope, motor discharges harmful gas with high-level discharge value.Owing to this reason, move in correct temperature range in order to ensure motor, the stable of coolant temperature and engine temperature helps efficient fuel combustion and reduces noxious gas emission.So that engine temperature is stable the design studies that reduces the noxious gas emission rate is had material impact.
The wax pattern thermostat is the most general technological scheme that motor is remained in the motor now in the correct temperature range.Its method of work is based on the expansion of wax composite owing to temperature rise.The wax composite is filled in the wax pocket, and it expands by temperature rise and drive the piston head of wax pocket, and this mechanism is called thermal actuator (or wax actuator).This expansion is opened valve, and design changes according to automatic temperature-control for this.
Therefore in-engine burning causes in-engine overheated and cause the overheated of freezing mixture on the thermostat.Be compressed in the expansion of the wax composite in the defined volume in the thermal actuator.The expansion of wax causes the linear motion of piston.Valve is opened in the linear motion of piston, and this makes the ANALYSIS OF COOLANT FLOW direction towards radiator, thereby reduces intrasystem coolant temperature with cooled engine.
The response period that is called automatic temperature-control from motor by freezing mixture to time of the expansion cost of the heat transmission of wax composite and wax composite.In this period, engine temperature keeps its ascendant trend, because Automatic temp. adjusting valve is not yet opened and coolant flow is cooled off to radiator.During this response period, engine temperature is higher than suitable motor running temperature, and fuel economy is lower, and forces motor to move under the higher temperature operating mode far above its design.
When the response time finished, Automatic temp. adjusting valve made freezing mixture flow towards radiator, and coolant temperature drops to the design temperature scope of appointment, so engine temperature drops to the design temperature scope of appointment.When coolant temperature drops to the design temperature of appointment when following, Automatic temp. adjusting valve owing to the response time during after the contraction of wax composite begin to move backward to closed position.Automatic temp. adjusting valve arrives closed position, and stops freezing mixture towards the circulation of radiator, and freezing mixture begins to heat up.But during this response period, engine temperature is lower than correct motor running temperature, and fuel economy is lower, and forces motor to move being lower than under its designed temperature.
Coolant flow not with situation that the wax container of Automatic temp. adjusting valve contacts under because the delay that heat is transmitted, cost longer time response period of Automatic temp. adjusting valve.The temperature that raises heats wax indirectly and lingeringly, so Automatic temp. adjusting valve postpones to open.Under reverse situation, when valve is opened, be lower than at coolant temperature in the situation of high efficience motor temperature range: the temperature of wax is because indirect heat transfer postpones decline in the same manner.The valve late release, and this causes lower engine temperature.On this class formation, owing to arrive the indirect heat transfer of the wax of Automatic temp. adjusting valve, not that total energy realizes engineer coolant temperature being kept and being stabilized in the efficient temperature range.
The model utility content
The utility model relates to a kind of automatic temperature-control valve assembly of the cool cycles for internal-combustion engine, and this automatic temperature-control valve assembly comprises: be fitted in the thermal actuator in the valve; Be placed on the valve and hinder the Sealing that flow of freezing mixture from the cluster engine to the radiator at the closed position place of valve; Be placed on the framework that covers; The spring that Forced Valve is closed when coolant temperature descends wherein, also comprises: the hole on the valve, so that coolant flow is led to radiator from cluster engine; And the coolant channel between thermal actuator and valve, so that freezing mixture responds interior direct heat transmission of period fast around thermal actuator.
In the utility model, in order between wax and freezing mixture, to carry out the Rapid Thermal transmission, the coolant channel around wax pocket is arranged, and in order to make freezing mixture flow through this passage, aperture (about 2mm) is arranged.Like this, always contact with wax pocket from the coolant flow of cluster engine, and wax can stand the temperature identical with the cluster engine temperature.This guarantees that Automatic temp. adjusting valve opens and closes motion according to real engine group temperature.

Embodiment
The wax composite is filled in the wax pocket, and it is owing to the piston head that temperature drives wax pocket expands, this mechanism is called thermal actuator 1, because the expansion of wax composite and the linear motion that contraction causes thermal actuator 1 piston in the capsule that causes of temperature variation, piston head is placed on the housing 7 at vertical axis place up and down.Thermal actuator 1 is fitted between interior each dowel pin of conduit of valve 3, thereby they can move together.The movement of thermal actuator opens or closes valve 3.At valve 3 Sealing 2 is arranged, thereby when valve is in the closed position (Fig. 5), hinders freezing mixture and flow to radiator between valve 3 and the housing 7 from cluster engine.
By the chute on the framework 4 at framework 4 interior pilot valves 3.Valve 3 carries out axial motion with thermal actuator 1 in framework 4.The piston of thermal actuator 1 is placed on the housing 7, and framework is placed on and covers on 6 (Fig. 5-6-7).
In the utility model, between thermal actuator 1 and valve 3, be useful on the passage 8 of freezing mixture.Radiator on hole 9 forms from the cluster engine to the motor is flowing around thermal actuator 1 continuously.Because freezing mixture flows around thermal actuator 1, so the heat transmission (Fig. 7) that thermal actuator 1 is directly arrived in realization.Wax composite in the coolant temperature heat hot actuator 1 that raises, the expansion of wax composite in thermal actuator moved piston, and it is opened valve 3 and does not have a delayed response period (Fig. 6).Opening of valve 3 forms the freezing mixture passage from the cluster engine to the radiator between valve 3 and the housing 7, is used for making coolant cools at the radiator place.
In the situation that coolant temperature descends, the volume of wax composite in wax pocket reduces, and spring 5 forces valve 3 to be closed.
