<p><P>PROBLEM TO BE SOLVED: To provide a flow rate control valve capable of preventing swing in a radial direction of a distal end of a valve body. <P>SOLUTION: A PCV valve 40 comprises: a case 42 provided with a gas passage 50; a valve body 60 provided reciprocatably in the gas passage 50; and a coil spring 72 biasing the valve body 60 in a retreating position. A metering hole 53 formed in the gas passage 50 and a metering surface 62 formed at the valve body 60 constitute a metering part 70. A flow rate of blow-by gas is controlled by adjusting a passage cross-sectional area of the metering part 70 by the movement of the valve body 60 in an axial direction. The coil spring 72 is interposed between a distal end 66 of the valve body 60 and a spring seat part 57 disposed downstream of the distal end 66 of the valve body 60 in the gas passage 50. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
