CONSTITUTION: A crankcase pressure control valve(1) is composed of a valve body(4) having a nipple(2) connected to a crankcase and a nipple(3) connected to a cylinder head cover, a diaphragm(5) installed in the valve body(4) and operated by the intake negative pressure of an engine, a spring(8) for supporting the diaphragm(5), and a protrusion tube(7) forming a gap(T) for passing blow-by gas. A gap control tube(9) is mounted on the end of the protrusion tube(7) to control the gap(T).
