Abstract
Provide is a PCV valve which can be quickly defreezed and provides a favorable sealing to the heater against the blow-by gas. The PCV valve (2) comprises a housing (6) defining a flow passage (4) for blow-by gas, a valve member (30) positioned in the flow passage to cooperate with a valve seat (18) formed in the housing, a spring (38) biasing the valve member toward the valve seat, a heat transmission member (40) including a heat dissipating part (42) surrounding the valve member, and a heating unit (52) including a heating element (66) for heating the heat transmission member, the heating element being separated from the flow passage in an air tight manner.
