摘要： PROBLEM TO BE SOLVED: To prevent wear of a seat part and a sliding part of a fuel injection valve at the time of supplying gaseous fuel without lubricating property. SOLUTION: A gaseous fuel supply system for an internal combustion engine is provided with a fuel injection vallve 2 for injecting and supplying gaseous fuel to the internal combustion engine 1 through a fuel piping 6, and a feed oil pipe 9 connecting the fuel piping 6 on the upper stream of the fuel injection valve 2 to an oil pump 10 for force-feeding oil for lubricating the internal combustion engine 1. Oil is mixed with the fuel piping 6 through the feed oil pipe 9. Oil is thus mixed with the nonlubricating fuel in the fuel piping 6 from the oil feed pipe 9 to impart lubricity to a seat part and a sliding part of the fuel injection valve 2, thereby preventing wear and improving durability. At the same time, wear of seat parts and sliding parts of an intake valve 16 and exhaust valve 17 on the downstream of the fuel injection valve 2 can be suppressed.

摘要： PROBLEM TO BE SOLVED: To provide a small size valve timing adjusting device preventing a rotating member at follower side from oscillating on controlling the phase and quickly reaching the target phase angle position even in the low pressure. SOLUTION: A lead angle piston 50 undergoes the oil pressure from a retardant angle oil pressure chamber 20 in a direction projecting from a lead angle bottom 55 to an inner perimeter 11a side of a circumference wall 11. A spring 52 energizes the lead angle piston 50 for opposite side of the projected side. The interval between the lead angle bottom 55 of a plate member 53 and an inner perimeter 11a of 11 is narrowed in such a direction that a vane rotor 15 leads for a shoe housing 10. If the lead angle piston 50 is projected from the lead angle bottom 55 toward the inner perimeter, a rotor 56 is not sandwiched between the inner perimeter 11a and the lead angle bottom 55. The rotor 56 is drawn in the opposite side of the inner perimeter 11a from the lead angle bottom 55, the rotor 56 is sandwiched between the inner perimeter 11a and the lead bottom 55 when the vane rotor 15 would rotate to the retardant angel side.
