Coolant surge tank for cooling system of combustion engine for vehicle, has pressure sensor measuring pressure of coolant and comprising signal transmitter for outputting control signal to electric engine controller

摘要

The tank has a pressure sensor (5) measuring pressure of coolant stored in the tank. The pressure sensor is provided in a sealing cover (1). The pressure sensor comprises a signal transmitter for outputting a control signal to an electric engine controller, where the control signal indicates the pressure of the coolant. An electric water pump provided in a cooling system is controlled using the control signal. The pressure sensor is formed as a unit with the sealing cover and directly arranged at a tank wall.
