Abstract:
A thermostatic cartridge assembly for a by-pass valve that regulates fluid flow between two different fluid circuits includes a casing defining a first fluid port and a second port; a thermostatic body having a piston movable along a central axis of the thermostatic body in response to heating and expansion of the thermally responsive material; a cap joined to a second end of the casing; a biasing member urging an end of the piston against a roof of the casing; and a sleeve carried by the thermostatic body, the sleeve having a circumferential side wall and a ceiling that seat against surfaces of the casing to block the first fluid port when the thermally responsive material is at a first temperature, the circumferential side wall blocking the second fluid port when the thermally responsive material is at a second temperature greater than the first temperature.

본 발명은 반도체 제조설비의 공정 챔버 등을 진공으로 만들어주는 진공펌프를 효율적으로 냉각시켜주는 기술에 관한 것이다. 본 발명은 진공펌프의 로터 내부에 오일을 순환시키는 방식으로 진공펌프의 내부 온도를 항상 일정 온도로 유지시켜주는 새로운 형태의 진공펌프 냉각방식을 구현함으로써, 진공펌프의 급격한 온도상승을 방지할 수 있고, 운전 초기에는 베어링의 원활한 윤활을 도모할 수 있는 등 공정 수행 및 펌프 구동의 안정성을 확보할 수 있으며, 설비의 경제적인 관리 및 유지를 가능하게 하는 한편, 진공펌프 냉각을 위한 오일을 순환시켜주는 펌프의 경우 외장형 또는 내장형 펌프를 적용하고, 또 냉각수 또는 펠티어 소자를 이용한 열교환 방식을 적용함으로써, 냉각효율 향상은 물론 공장 여건에 맞는 최적의 레이아웃 설계를 가능하게 하고, 또 로터측 온도 및 오일 온도를 체크하여 펌프 내부로 흡입되는 가스의 유량에 따라 오일의 온도를 자동으로 가변 제어하는 방식을 적용함으로써, 진공펌프의 가동효율을 높일 수 있는 냉각장치를 갖춘 진공펌프를 제공한다.
Abstract:
A system for cooling an engine on a vehicle without a coolant based intercooler and intermediate duct, the system including an air-to-oil radiator system configured to cool oil that flows through an engine, an air-to-air radiator system configured to cool air that flows through the engine and further configured to operate in conjunction with the air-to-oil radiator system to provide cool air for use with the air-to-oil radiator system, and a slow flow coolant radiator configured to cool a coolant provided to cool the engine and further provided to operate in conjunction with the air-to-oil radiator system. A method for cooling oil in an engine without a coolant based intercooler and intermediate duct is also disclosed.
Abstract:
A cooling system for internal combustion engines provides directed flows of heated or cooled coolant to various engine components and/or accessories as needed. By providing directed flows, the overall coolant flow volume is reduced from that of conventional cooling systems, allowing for a smaller capacity water pump to be employed which results in a net energy savings for the engine. Further, by reducing the overall coolant flow volume, the hoses and/or galleries required for the directed flows are reduced from those of conventional cooling systems, providing a cost savings and a weight savings. Finally, by preferably employing an impellor type water pump, the expense of an electric water pump and its associated control circuitry can be avoided. The direct flows are established by a multifunction valve which , in a preferred implementation, comprises a two-plate valve wherein each plate is operated by a wax motor.
Abstract:
Die Erfindung betrifft ein System zum Temperieren eines Motoröls einer Brennkraftmaschine eines Kraftfahrzeugs, das einen Motorölkreis (25) zum Temperieren eines Motoröls, der die Brennkraftmaschine (10) und einen Kühlmittel-Motoröl-Wärmetauscher (28) umfasst; und einen Kühlmittelkreis (11) zum Temperieren der Brennkraftmaschine (10), der in einem Hauptzweig (11 1 ) die Brennkraftmaschine (10), einen Kühlmittelkühler (12) und eine erste Kühlmittelpumpe (16) und in einem Nebenzweig stromab des Kühlmittelkühlers (12) den Kühlmittel-Motoröl-Wärmetauscher (28) und eine zweite Kühlmittelpumpe (36) umfasst, enthält. Die Wärme des Motoröls kann so über den Kühlmittel-Motoröl-Wärmetauscher (28) an das Kühlmittel und weiter über den Kühlmittelkühler (12) an die Umgebung abgegeben werden. Selbst bei einer begrenzten Kühlkapazität des Luft-Motorölkühlers (26) kann so durch das Niedertemperatur-Kühlmittel und durch die gepumpte Kühlmittelmenge eine geeignete Motoröltemperierung gewährleistet werden.
