バルブ。The opening area of the orifice provided in the valve housing is made variable by a valve body that is installed in the blow-by gas return passage and responds to the pressure difference between the inlet side and the outlet side of the valve housing, thereby controlling the amount of suction of blow-by gas to be increased or decreased. In the PCV valve, the valve body is formed of a permanent magnet, a spring is provided to press the valve body to the valve opening seat provided on the inlet side, and the valve body is placed near the valve opening seat during engine operation. PCV of an internal combustion engine, characterized in that it is provided with an electromagnet that is excited so as to repel against a spring force.
