<P>PROBLEM TO BE SOLVED: To provide a lubricating device capable of properly performing lubrication of using microbubbles. <P>SOLUTION: This lubricating device 1 is characterized by having a discharge port 30 arranged in a control valve 29 for controlling a liquid medium supplied to a power transmission device for transmitting power to a driving wheel from a traveling driving source 3 of a vehicle and generating the microbubbles in the liquid medium by pressure reduction when discharging the liquid medium from the inside of the control valve 29, a microbubble mixed medium supply passage 31 for connecting the discharge port 30 and frictional engaging elements 18 and 19 of the power transmission device, and a required pressure generating device 32 for generating pressure of the required size for generating the microbubbles in the liquid medium by the pressure reduction when discharging the liquid medium from the inside of the control valve 29 via the discharge port 30, as pressure of the liquid medium introduced in the control valve 29. Thus, the lubricating device 1 performs the effect capable of properly performing the lubrication of using the microbubbles. <P>COPYRIGHT: (C)2013,JPO&INPIT |
