Abstract
An arrangement is provided for controlling the coolant temperature in a coolant circulating system of an internal-combustion engine, such as in a motor vehicle, containing a thermostatic valve that controls the coolant flow from the internal-combustion engine through a direct return flow means and/or through a heat exchanger back to the internal-combustion engine, and containing a thermostatic working element having a housing carrying a valve disk of a valve controlling coolant flow to the heat exchanger, and having a working piston extendable under heat and being supported at a counterbearing. The working piston and the counterbearing form an adjusting mechanism, and a control element is connected to the working piston or the counterbearing which forces the working piston into an adjusted position.
Claims14
An arrangement for controlling the temperature in a coolant circulating system of an internal-combustion engine of a motor vehicle, which includes a thermostatic valve means for controlling the coolant flow from said internal-combustion engine through a direct return flow line and through a heat exchanger back to said internal-combustion engine, a thermostatic working element having a housing supporting a valve disk for controlling coolant flow leading to said heat exchanger, and a working piston extending under heat relative to said thermostatic working element and being, supported at a counterbearing, said working piston and said counterbearing forming an adjusting mechanism, and control means, connected to said working piston or said counterbearing, for forcing said working piston into an adjusted position selectively to delay or accelerate actuation of the thermostatic working element.
An arrangement for controlling the temperature in a coolant circulating system of an internal-combustion engine of a motor vehicle, comprising:
- inlet means for providing coolant flow from said internal combustion engine, direct return flow means for providing coolant flow to said internal-combustion engine, heat exchanger means for receiving said coolant, thermostatic valve means for controlling coolant flow through said heat exchanger means from said inlet means, a thermostatic working element having a housing carrying a valve disk of said thermostatic valve means and having a working piston, extendable relative to said working element in response to temperature and supported at a counterbearing, said working piston and said counterbearing forming an adjusting mechanism, and control means for forcing said working piston into an adjusted position selectively to delay or accelerate extension of the thermostatic working element, the control means being connected to said adjusting mechanism.
An apparatus for thermostatically controlling the temperature of coolant fluid circulating in a motor comprising:
- inlet means for receiving coolant flow from said motor;
- direct return means for providing coolant flow to said motor;
- connecting sleeve means for providing coolant flow to heat exchanger means;
- thermostatic valve means for selectively communicating said inlet means with said direct return means and with said connecting sleeve means, including valve disk means for controlling coolant flow through said direct return means and connecting sleeve means, and thermostatic working element means for actuating said valve disk means;
- counterbearing means for supporting the thermostatic working element means, and
- adjustment means for altering the actuation of said thermostatic working element means in response to external parameters, including control means for moving said thermostatic working element means relative to the counterbearing means.
An arrangement for controlling the temperature in a coolant circulating system of an internal-combustion engine of a motor vehicle, which includes a thermostatic valve means for controlling the coolant flow from said internal-combustion engine through a direct return flow line and through a heat exchanger back to said internal-combustion engine, a thermostatic working element having a housing supporting a valve disk for controlling coolant flow leading to said heat exchanger, and a working piston extending under heat relative to said working element and being supported at a counterbearing, said working piston and said counterbearing forming an adjusting mechanism, and a control means for forcing said working piston into an adjusted position, connected to said working piston or said counterbearing, wherein said working piston is provided with an axial toothing into which a pinion engages that is formed as said counterbearing, said piston being connected to said control means.
