PROBLEM TO BE SOLVED: To provide a PCV valve for rapidly resolving frozen moisture within the valve and showing a superior sealing characteristic of a heater element against blow-by gas.SOLUTION: A PCV valve (2) comprises: a housing (6) forming a flow passage (4) for blow-by gas; a valve body (30) arranged in a flow passage and cooperating with a valve seat (18) installed in the housing; a spring (38) for biasing the valve body toward the valve seat; a heat transfer body (40) having a heat radiation part (42) for outwardly enclosing the valve body; and heating means (52) air-tightly spaced apart against the flow passage and having a heating body (66). One end side of the heat transfer body is received in a receiving hole (50) formed at the housing. The heating means is arranged to heat the one end side of the heat transfer body through a partition wall (58) defining a part of the receiving hole and air-tightly spaced apart against the flow passage. |
