System For Monitoring The Position Of A Valve Body In A Value Unit And A Value Unit For A Coolant Circuit Of An At Least Partially Electrically Driven

Abstract

A system for monitoring the position of a valve body in a valve unit for a coolant circuit of an at least partially electrically powered vehicle includes: a valve housing for accommodating a valve body, wherein the valve body is accommodated in the valve housing between a first position, in which the valve body is arranged in contact with a valve seat and closes the valve unit, and a second position, in which the valve body is spaced from the valve seat and the valve unit is at least partially open, a piston rod for transmitting a drive movement to the valve body, wherein the piston rod includes a recess for accommodating a permanent magnet, and a sensor unit fixedly arranged in relation to the valve seat and designed to detect a position of a permanent magnet accommodated in the recess.
