摘要： In the case of a cooling system for an internal-combustion engine of a motor vehicle comprising a radiator and a thermostatic valve by means of which the temperature of the coolant can be controlled in a warm-up operation, a mixed operation and a radiator operation. The thermostatic valve containing an expansion element can be electrically heated for reducing the coolant temperature, the expansion element being designed such that the coolant temperature is controlled without any heating of the expansion element in the warm-up operation and/or the mixed operation to an upper operating limit temperature. In addition, a temperature switch is provided which, as a function of the coolant temperature detected at the or near the radiator outlet, releases the heating of the expansion element as required in order to shift the method of operation of the cooling system toward the radiator operation.

摘要： A thermostatic valve arranged in the coolant circuit of an internal-combustion engine, has a main valve which is acted upon by cold coolant flow on the one side, and by hot coolant flow on the other side. The valve is actuated as a function of the coolant temperature by way of an expansion material element equipped with an electric heating device. To minimize the coldside influence onto the expansion material element, a capsule which stores the expansion material, has an end which limits the expansion material lower at the level of the closed main valve or on the mixing chamber side. At this end, a ring-shaped or sleeve-shaped heating element is arranged coaxially adjacent the control pin, or, individual heating elements are distributed along the circumference of the control pin in an adjacent manner.

摘要： An improved unified cooling system for an internal combustion engine that generally includes a cylinder head and a cylinder block, in which the cylinder head and cylinder block are maintained at different operating temperatures despite using only a single coolant pump. The coolant pump pumps fresh coolant through the cylinder head and cylinder block. Coolant valves, which may be thermostatic valves or electrically actuable proportional valves, lie downstream of the cylinder head and cylinder block and individually control the amount of coolant flowing through the cylinder head and cylinder block so as to maintain a lower operating temperature for the cylinder head than for the cylinder block. Coolant is directed, in various configurations, through any or all of an oil cooler, a heat exchanger for a heater for a vehicle interior, and a coolant radiator, before being directed back to the coolant pump.

摘要： A force-balanced lifting valve for the control of a fluid, comprises a housing having paths for the fluid, an axially movable component in the form of a valve body provided on a shaft mounted so as to be axially movable in the housing, for the opening and closing a valve opening, and a sealing structure for sealing the axially movable component with respect to the housing. The valve body has associated therewith a force-balancing compensation area, which can be acted upon by pressure fluid by way of a subsidiary channel. The sealing structure comprises an elastic, axially effective sealing ring which sealingly engages the valve housing and the axially movable valve component, such that a radial portion of the ring rests axially and sealingly against at least one abutment shoulder on the axially movable valve component.

摘要： A method of cooling coolant in a coolant circuit of an internal combustion engine of a motor vehicle includes: evaluating parameters of the internal combustion engine and the motor vehicle with a thermostatic valve control device; based on the evaluation of the parameters, controlling with the thermostatic valve control device adjustment of a thermostatic valve for controlling coolant flow from a radiator and coolant flow from a bypass line around the radiator into a combined coolant flow to the internal combustion engine; communicating a signal based on the evaluation of the parameters from the thermostatic valve control device to a fan control device which controls operation of a fan that cools coolant in the radiator to a target temperature; and setting the target temperature of the fan control device through the communication. Subsequently, the fan control device controls the cooling by the fan as a function of the target temperature set by the signal received from the thermostatic valve control device.
