LUBRICATING DEVICE
Document Type and Number:
Japanese Patent JPS58137694
Kind Code:
A
Abstract:
PURPOSE:To reduce water-hammer effect and decrease noise by a method wherein a notch is provided at the opening section of an oil path. CONSTITUTION:Openings 18A, 18B are communicated with oil holes 13, 12 through notches 24, 25 before the opening 18C of an oil path 18 is communicated with an oil inlet hole 10. At this moment, the pressure in the oil path 18 is not so high since the oil inlet hole 10 is not communicated therewith. Accordingly, an impact occuring when the oil in the oil path 18 is flowed out toward the oil holes 12, 13 is not so high. Thereafter, when the opening 18C is communicated with the oil inlet hole 10, the oil is supplied into the oil path 18, however, the oil in the oil path 18 is flowed out into the oil holes 12, 13 already upon this moment, therefore, the water-hammer effect is reduced and the noise may also be decreased.
