THERMOSTAT BODY

The invention relates to transport engineering, in particular to design of housing parts for thermostats of liquid cooling system of internal combustion engines (ICE). A thermostat body comprises two covers 1,2 connected therebetween and formed by cylindrical surfaces 3,4. The first cover 1 has a flange 5 for connection with a flange (not shown) of a collector of the ICE water cooling system and also has a branch pipe 6 for communication with an expansion tank (not shown). The second cover 2 has a branch pipe 7 for communication with a radiator (not shown). The first cover 1 flange 5 is arranged at an acute angle to its cylindrical surface 3 smoothly transforming into the first cover 1 branch pipe 6 via a conical surface 8. Wherein the second cover 2 is also formed by a spherical surface 9 smoothly transforming into the second cover 2 branch pipe 7 via its cylindrical surface 4. The invention has embodiments with the following features: A polymer material can be used for covers. Two short through holes 10 and two long through holes 11 are made in the first cover 1 flange 5 arranged in bosses 12 of the cylindrical surfaces 12. Four short through holes 10 are made in the first cover 1 flange 5 with slots for insert nuts. Both covers 1,2 have docking flanges forming arch-like end surfaces which, when covers 1,2 not tied contact by two short parts, and when tied by means of two bolt connections 17 - are in full touch. For that purpose the cover material is selected having elastic-deformable properties. Both covers can be screwed together or bayonet joined. Such covers can be locked either by comb-shaped gearing or by a pin or a finger. A bracket can be made on the side surface of the second cover 2 with a recess for entering a locking element through one of four short holes 10 of the first cover 1 flange 5. Изобретение относится к транспортному машиностроению и касается конструкции корпусных деталей для термостатов системы жидкостного охлаждения двигателей внутреннего сгорания (ДВС). Корпус термостата (фиг. 1) содержит скрепленные между собой две крышки 1, 2, которые образованы цилиндрическими поверхностями 3, 4. Первая крышка 1 снабжена фланцем 5 для соединения с фланцем (не показано) коллектора системы водяного охлаждения ДВС, а также патрубком 6 для сообщения с расширительным бачком (не показано). Вторая крышка 2 снабжена патрубком 7 для сообщения с радиатором (не показано). Фланец 5 первой крышки 1 расположен под острым углом к ее цилиндрической поверхност
