Abstract
A valve unit for an internal combustion engine includes a duct, a valve and a shaft. The duct includes an inner tube defining a gas passage and an outer tube disposed radially outside of the inner tube. The duct has an annular liquid storage groove between the outer tube and the inner tube. The valve is supported by the shaft in the inner tube to control the gas passage The shaft is held by a bearing portion of the duct. The inner tube has an overflow portion and an overflow-restricting portion at an upper end. The overflow portion regulates a level of liquid stored in the storage groove and allows excess liquid to overflow from the storage groove. The overflow-restricting portion is provided in a predetermined area above the bearing portion and located higher than the overflow portion to restrict the liquid from overflowing from the predetermined area.
