Abstract: An oil separator includes: an oil separator main body that is formed with a gas flow path between a gas introduction port that introduces blow-by gas and a gas discharge port that discharges the blow-by gas; a flap that opens and closes the gas flow path, and that includes a substantially circular shaped valve section including a straight line portion of a substantially straight line shape at a portion of an outer periphery of the valve section; and a first impact wall for capturing oil, that is provided along the outer periphery of the valve section at a downstream side of the valve section in the gas flow path, that includes a straight line portion of a substantially straight line shape along the straight line portion of the valve section, and that is impacted by the blow-by gas flowing out from a peripheral edge of the valve section.

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.

Abstract: A hose connector comprises a connector main body (12, 112, 190), a lock member (14, 82, 88, 94, 114), a cam mechanism (70, 170: 68, 168, 194) that converts the rotational movement of the lock member into an axial movement thereof, and clamping features (24; 42, 142) formed in the inner and outer circumferential surfaces of the lock member and the connector main body which clamps a hose end by moving axially toward each other. The hose end can be connected to a pipe or a pipe-like member with ease in a reliable manner and without requiring a tool.
