涡轮增压器电控式冷却供油装置
摘要：
本实用新型公开了一种涡轮增压器电控式冷却供油装置，包括连接于发动机润滑油供应系统与涡轮增压器进油口间的进油管回路，还包括进油口和出油口并接于进油管回路上的储压罐；所述储压罐的进油口经第一单向阀连接于进油管回路上；所述进油管回路上相应于储压罐进油口的接点与出油口的接点之间处设有第二单向阀；储压罐的出油口处设有由ECU控制的电磁开关。本实用新型公开的涡轮增压器电控式冷却供油装置，可在发动机停机时，对涡轮增压器的轴承和转子冷却润滑，具有结构简单、便于安装布位、成本低廉、开发周期短的特点。本实用新型适合安装于各种车用涡轮增压发动机上。
摘要（英）：

The utility model discloses an electric-control cooling and oil supply device for a turbocharger, which comprises an oil inlet pipe loop connected between a lubricating oil supply system of an engine and an oil inlet of the turbocharger, and a pressure storage tank, wherein an oil inlet and an oil outlet of the pressure storage tank are in parallel connection with the oil inlet pipe loop; the oil inlet of the pressure storage tank is connected with the oil inlet pipe loop by a first one-way valve; a second one-way valve is arranged between connection points corresponding to the oil inlet and the oil outlet of the pressure storage tank on the oil inlet pipe loop; and an electromagnetic switch controlled by an ECU (electronic control unit) is arranged at the oil outlet of the pressure storage tank. The electric-control cooling and oil supply device for the turbocharger can cool and lubricate a bearing and a rotor of the turbocharger when the engine stops, and has the characteristics of simple structure, convenience in mounting and location, low cost and short development period. The electric-control cooling and oil supply device can be mounted on various vehicular turbocharged engines.
