PROGRAMMABLE TEMPERATURE CONTROLLER Russian patent published in 2005 - IPC

FIELD: mechanical engineering; internal combustion engines.

SUBSTANCE: invention can be used in vehicle internal combustion engines. Proposed temperature controller containing housing with branch pipes to supply cooling liquid from engine, and direct cooling liquid for bypassing and to radiator, temperature transmitter, sealing element, two valves installed inside housing on rod, temperature transmitter, control unit, reciprocating actuating mechanism, and spring is furnished additionally with load sensor, setter and comparator whose input is connected to temperature transmitter and load sensor, and output is connected to control unit made programmable for changing temperature at variable loads. Moreover, temperature controller contains ultrasonic device whose input is connected with control unit and output, through transmitters and receivers installed on branch pipes directing liquid for bypassing and to radiator, as well as amplifier, are connected to phase-meter. Invention makes it possible to maintain higher temperature of cooling liquid at partial loads, warming up, especially at low ambient temperatures, and purposeful maintenance of low temperature at rated loads of engine and timely elimination of faults in valve system.

EFFECT: enhanced operation.
