Abstract
A PCV valve coupling structure that couples a PCV valve to an internal combustion engine is employed in the PCV valve used to adjust a gas flow area of a blow-by gas passage. Blow-by gas in the internal combustion engine flows to an intake system of the internal combustion engine. In the PCV valve coupling structure, the PCV valve is coupled to the internal combustion engine in a non-removable manner.
Claims3
A PCV valve coupling structure employed in a PCV valve used to adjust a gas flow area of a blow-by gas passage through which blow-by gas in an internal combustion engine flows to an intake system of the internal combustion engine, the PCV valve coupling structure coupling the PCV valve to the internal combustion engine,
- the PCV valve coupling structure comprising a plate-shaped coupling member that is separate from the PCV valve and used to couple the PCV valve to the internal combustion engine in a non-removable manner, wherein
- the plate-shaped coupling member includes a fixation hole, and
- the plate-shaped coupling member is attached to the internal combustion engine by a plastically deformed deformation part protruding from the internal combustion engine and extending through the fixation hole so that the plate-shaped coupling member couples the PCV valve to the internal combustion engine in the non-removable manner.
