Abstract
The utility model relates to an automatic temperature adjustment valve assembly for the cooling cycle of an internal combustion engine. The valve assembly stabilizes coolant temperature within the design scope of the internal combustion engine. The valve assembly comprises a thermal actuator assembled in the valve, and a sealing member arranged in a groove of the valve. When the valve is in a closed position, the sealing member stops the coolant flow from an engine set to a radiator. The valve further comprises a cover framework and a spring. When the coolant temperature decreases, the spring forces the valve to close.
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 conduit 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.
The internal-combustion engine thermostat is by opening and closing its valve on the coolant flow passage from the cluster engine to the radiator, and the temperature that will regulate according to them opens or closes carries out this function.They are adjusted to the high efficience motor temperature range.Be higher than in temperature in the situation of high efficience motor temperature, Automatic temp. adjusting valve is opened to flowing so that freezing mixture is cooled off of radiator.Under the lower temperature state, Automatic temp. adjusting valve is in the closed position.
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 wax composite that can expand 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.By using suitable wax composite that they are adjusted to the high efficience motor temperature range, the expansion temperature of wax composite and engine high-efficiency temperature are complementary.This expansion makes valve open by a mechanism freezing mixture to be turned cold, and design changes according to automatic temperature-control in this mechanism.Wax pattern automatic temperature-control structure can change.
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, comprise: be fitted in the thermal actuator in the valve, be placed on the Sealing on the groove on the valve, the seal hinders freezing mixture flowing from the cluster engine to the radiator at the closed position place of valve, framework with framework claw, this framework claw stably is fixed on thermostat in the housing, spring, Forced Valve was closed when this spring descended at coolant temperature, wherein, inside claw in the valve is so that the thermal actuator that is press-fitted and valve are mobile with framework, and by-pass baffles and semi-circular channel form induced flow.
The utility model is a kind of alternative automatic temperature-control assembly, it comprises Sealing, spring, framework on typical wax actuator, valve, the valve, Sealing is closed to the ANALYSIS OF COOLANT FLOW of radiator under valve is placed in situation on the housing, Forced Valve was closed when spring descended at coolant temperature, and valve guides in framework.

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 linear motion that the expansion of the interior wax composite of the capsule that temperature variation causes and contraction produce thermal actuator 1 piston, piston head is placed on the housing 14.Thermal actuator 1 is fitted between the inside claw 13 of valve 3, thereby they can move (Fig. 3-Fig. 4) together.Thermal actuator 1 press fit over to be reinforced valve arm 5 and prevents that valve arm 5 from stretching between the inner claw 13, thereby avoids valve 3 to throw off from framework 9, and valve 3 is assembled in the chute 12 of framework 9 by valve claw 6.The movement of thermal actuator 1 opens or closes valve 3.At valve 3 Sealing 2 that is placed in the groove 4 is arranged, thereby when valve 3 is in the closed position, hinders freezing mixture and flow to radiator between valve 3 and the housing 14 from cluster engine.
Valve claw 6 guides in framework 9 by the chute 12 on the internal surface of cylinder-shaped frame 9.Valve 3 carries out its linear motion with thermal actuator 1 by valve arm 5 in framework 9.The piston of thermal actuator 1 is placed on the housing 14, and the flange side of framework 9 is placed on (Fig. 5) on the housing 14 by the framework claw 10 in the conduit that is placed on housing 14.These framework claws 10 stably are fixed on thermostat in the housing 14 and the power of spring 7 are not reacted (reflect) to lid 15.The outside skirt section of framework 9 be placed on the housing 14 and guarantee housing 14 and framework 9 between sealing.
The coolant temperature that raises is reacted to the wax composite in the thermal actuator 1, and the expansion of wax composite in thermal actuator moved piston, and valve 3 is opened in this movement.By valve 3 is opened from large cross section, high ANALYSIS OF COOLANT FLOW arrives radiator from cluster engine, thereby reduces coolant temperature at radiator.In this position that is called the valve open position, valve arm 5 is downward by framework 9, and the valve arm centers on by the by-pass baffles 8 of framework 9, thereby it hinders flowing of on cooling system bypass path.Only have by a small amount of of baffle plate 8 first circular channels 11 and flow, this guarantees that the true temperature of freezing mixture is identical on the temperature of the freezing mixture of thermal actuator 1 and the cooling system.This feature helps thermal actuator 1 correctly mobile according to the system temperature of reality.
In the situation that coolant temperature descends, the volume of wax composite in wax pocket reduces, and spring 7 forces valve 3 to be closed.Spring 7 is arranged between the flange of valve 3 and framework 9.
