Flow control valve for vehicle heat carrier circulation esp. for heating circuit - uses electric motor which without additional sealing measures lies completely in heat carrying circulation flow led inside valve housing.

摘要

The electric motor (4) operates the closing part (5) of the valve working in conjunction with the valve seat (6). Special sealing measures are provided at the valve housing for the sealing of the electrical connecting cable (8), for the motor. The connection cable (8) is led through at least one chamber (9a,9b), which is sealed against the heat carrying flow and the valve surroundings. ADVANTAGE - Flow control valve is simplified compared to known unit using stepper motor which is esp. small and compact.
