Crankcase ventilation system for internal-combustion engine, has diaphragm performing movement between closed and opened positions, and magnet element and hall sensor sensing movement of diaphragm and arranged in housing of system

摘要

The system (1) has a pressure regulating valve (4) provided in a flow path of an air flow coming from a crankcase. The pressure regulating valve comprises a diaphragm (5) performing an adjustment movement between a closed position and an open position. A magnet element (9) and a hall sensor (10) sense the adjustment movement of the diaphragm and are arranged in a housing (2) of the system. The magnet element and the hall sensor are arranged at the housing and the diaphragm. A thrust ring (6) is connected with the diaphragm.
