Abstract

PURPOSE: To increase the cooling effect and uniformalize the frictional wear by providing part of the frictional contact surface of the water sealing device of the hydraulic machine with a passage and passing a cooling medium through the passage.
CONSTITUTION: A water supply groove 11 is formed on the frictional surface side of a packing 7 capable of frictional movement over a sleeve 8, and a passage is formed. Thus, a cooling medium flows through a water supply hole 10 formed in a packing box 4 and a water supply hole 12 formed in a packing 7 into the water supply groove 11, thus providing an effective cooling effect with respect to the heat of friction between the sleeve 8 and packing 7. In addition, since the water supply groove 11 provided on the packing 7 is adapted to engage with the entire frictional surface, the wear can be uniformalized.
