摘要： PROBLEM TO BE SOLVED: To provide a blow-by gas recovery structure of an internal combustion engine and a chain cover unit used in the blow-by gas recovery structure capable of preventing sludge by suppressing dew condensation of water in a middle of a blow-by gas recovery path. SOLUTION: The blow-by gas recovery structure includes the chain cover unit 10 formed of a chain cover body 11, and an oil pump cover 12. The chain cover unit 10 is mounted on a cylinder block, and a space formed between the chain cover unit 10 and the cylinder block is utilized as the blow-by gas recovery path A. Ribs 12g, 12g for reducing a flow rate of blow-by gas by narrowing the blow-by gas recovery path A are integrally formed around an oil discharge port 12e of the oil pump cover 12. Thereby, a part which provides an oil separation function is heated by engine oil, and the dew condensation of the water contained in the blow-by gas can be prevented. COPYRIGHT: (C)2008,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To control malfunction of a slider caused by freezing of condensation in a pressure chamber in a power transmitting mechanism which changes the magnitude of a driving force applied to a part to be driven by displacing the slider by guiding a negative pressure into the pressure chamber.
SOLUTION: The power transmitting mechanism of the water pump 10 is provided with a VSV45 and a check valve 63. The position of the valve of the VSV45 connected to a negative pressure chamber 31b can be switched between a state where an air-intake passage 60 and the negative pressure chamber 31b are connected to each other and a state where the negative pressure chamber 31b and the atmospheric-air guiding part 44 are connected to each other. The check valve 63, which is provided in a negative pressure passage 62 connecting the VSV45 to the air-intake passage 60, is opened only when the negative pressure is guided to the negative pressure chamber 31b through the VSV45. The VSV45 is positioned in a valve position which enables the negative pressure chamber 31b and the air-intake passage 60 to be connected to each other at the time of non-energization, and is brought into a non-energization state at least after the engine stop.
